WPF Bar Chart how to add space between bars?

I am using Telerik (RadPieChart) with WPF. What I want to do is add a small space between the bars. I am not asking about the space between the series, as that is already available, but about a smaller space between the bars just as shown in the image examples below.
Here is what I have now:
And this is how I would like my Bar Chart to look like with a small space between them:
This is my source code:
private BarSeries CreateBarSeries(KeyValuePair<ChartSerie, List<ChartDataPoint>> chartSeries, ChartLegendSettings legendSettings, int colorPaletteIndex)
{
var isStackMode = chartSeries.Key.CombineMode == SeriesCombineMode.Stack;
var barSerie = new BarSeries()
{
VerticalAxis = CreateMultipleVerticalAxis(chartSeries, colorPaletteIndex, out var multipleVerticalAxis) ? multipleVerticalAxis : null,
LegendSettings = legendSettings,
StackGroupKey = chartSeries.Key.Group,
Opacity = 0.8,
ZIndex = 120,
CombineMode = string.IsNullOrEmpty(chartSeries.Key.Group)
? ChartSeriesCombineMode.Cluster
: (isStackMode ? ChartSeriesCombineMode.Stack : ChartSeriesCombineMode.Stack100),
// start animations
//PointAnimation = new ChartMoveAnimation()
//{
// MoveAnimationType = MoveAnimationType.Bottom,
// Duration = new TimeSpan(0, 0, 0, 0, 600),
// Delay = new TimeSpan(0, 0, 0, 0, 155),
// //Easing = new ElasticEase()
// //{
// // EasingMode = EasingMode.EaseOut,
// //},
//},
LabelDefinitions =
{
// set the clarion format for the labels
new ChartSeriesLabelDefinition()
{
Template = new DataTemplate()
{
VisualTree = GetSeriesFormat(chartSeries),
}
}
}
};
// this is the color of bar series
if (chartSeries.Key.ColorHex != null)
{
Style style = new Style(typeof(Border));
style.Setters.Add(new Setter(Border.BackgroundProperty, (SolidColorBrush)(new BrushConverter().ConvertFrom(chartSeries.Key.ColorHex))));
barSerie.DefaultVisualStyle = style;
}
foreach (ChartDataPoint serie in chartSeries.Value)
{
barSerie.DataPoints.Add(new CategoricalDataPoint()
{
Category = serie.XPoint.Label,
Value = (double?)serie.Value,
});
}
return barSerie;
}
The answer:
For some reason adding the BorderThickness to the Style as suggested in one of the answers did not do the trick, although BorderThicknes should be the solution. So I added a PointTemplate with a VisualTree and there I defined the BorderThickness. Now it is working perfectly.
private BarSeries CreateBarSeries(KeyValuePair<ChartSerie, List<ChartDataPoint>> chartSeries, ChartLegendSettings legendSettings, int colorPaletteIndex)
{
var seriesPredefinedColor = this.ChartBase.Palette.GlobalEntries[colorPaletteIndex].Fill;
FrameworkElementFactory borderFramework = new FrameworkElementFactory(typeof(Border));
borderFramework.SetValue(Border.BackgroundProperty, ColorService.BrushFromHex(chartSeries.Key.ColorHex) ?? seriesPredefinedColor);
borderFramework.SetValue(Border.OpacityProperty, 0.8D);
borderFramework.SetValue(Border.BorderThicknessProperty, new Thickness(2));
borderFramework.AddHandler(Border.MouseEnterEvent, new MouseEventHandler((sender, args) =>
{
var seriesBorder = (Border)sender;
//seriesBorder.BorderBrush = new SolidColorBrush(Colors.Black);
//seriesBorder.BorderThickness = new Thickness(1);
seriesBorder.Opacity = 1;
}));
borderFramework.AddHandler(Border.MouseLeaveEvent, new MouseEventHandler((sender, args) =>
{
var seriesBorder = (Border)sender;
//seriesBorder.BorderBrush = new SolidColorBrush(Colors.Black);
//seriesBorder.BorderThickness= new Thickness(1);
seriesBorder.Opacity = 0.8;
}));
var isStackMode = chartSeries.Key.CombineMode == SeriesCombineMode.Stack;
var barSerie = new BarSeries()
{
VerticalAxis = CreateMultipleVerticalAxis(chartSeries, colorPaletteIndex, out var multipleVerticalAxis) ? multipleVerticalAxis : null,
LegendSettings = legendSettings,
StackGroupKey = chartSeries.Key.Group,
ZIndex = 120,
IsHitTestVisible = true,
CombineMode = string.IsNullOrEmpty(chartSeries.Key.Group)
? ChartSeriesCombineMode.Cluster
: (isStackMode ? ChartSeriesCombineMode.Stack : ChartSeriesCombineMode.Stack100),
// start animations
//PointAnimation = new ChartMoveAnimation()
//{
// MoveAnimationType = MoveAnimationType.Bottom,
// Duration = new TimeSpan(0, 0, 0, 0, 600),
// Delay = new TimeSpan(0, 0, 0, 0, 155),
// //Easing = new ElasticEase()
// //{
// // EasingMode = EasingMode.EaseOut,
// //},
//},
LabelDefinitions =
{
// set the clarion format for the labels
new ChartSeriesLabelDefinition()
{
Template = new DataTemplate()
{
VisualTree = GetSeriesFormat(chartSeries),
}
}
},
PointTemplate = new DataTemplate()
{
VisualTree = borderFramework,
}
};
// this is the color of bar series
//if (chartSeries.Key.ColorHex != null)
//{
// Style style = new Style(typeof(Border));
// style.Setters.Add(new Setter(Border.BackgroundProperty, (SolidColorBrush)(new BrushConverter().ConvertFrom(chartSeries.Key.ColorHex))));
// barSerie.DefaultVisualStyle = style;
//}
foreach (ChartDataPoint serie in chartSeries.Value)
{
barSerie.DataPoints.Add(new CategoricalDataPoint()
{
Category = serie.XPoint.Label,
Value = (double?)serie.Value,
});
}
return barSerie;
}

Set the BorderThickness property of the DefaultVisualStyle of the BarSeries:
// this is the color of bar series
if (chartSeries.Key.ColorHex != null)
{
Style style = new Style(typeof(Border));
style.Setters.Add(new Setter(Border.BackgroundProperty, (SolidColorBrush)(new BrushConverter().ConvertFrom(chartSeries.Key.ColorHex))));
style.Setters.Add(new Setter(Border.BorderThicknessProperty, new Thickness(2.0)));
barSerie.DefaultVisualStyle = style;
}

have you look into this ? seem default is 0 mean bar take all the space

Xamarin bind a dynamic list of images to a grid

first of all sorry for the mess, I'm kicking my head in this for a while already, I'm kind new in xamarin and starting with difficult problems. I'm trying to add dynamically a list of random images in a grid.
currently i have the grid printing like
Name1 Detail1
filename1 filename2 filename3
Name2 Detail2
Filename1 filename2
var cell = new DataTemplate(() => {
var grid = new Grid() { Padding = 8, RowSpacing = 5, ColumnSpacing = 5 };
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Auto) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Auto) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(50, GridUnitType.Star) });
Subtitle.SetBinding(Label.TextProperty, "Images");
grid.Children.Add(labelName, 0, 0);
grid.Children.Add(labelDetail, 1, 0);
grid.Children.Add(Subtitle, 1, 1);
the cell in the end is attached to a listview
listdata.ItemTemplate = cell;
in the Object I have defined images as a string, I already tried to create another bind to a list, and create a listview of a custom call and add it to the grid, but throws an error and I can't see any description, it's something like sigsegv-without-stack trace
Also tried to instead of a grid, create a stack layout. again nothing.
CustomCell
public class CustomNocCell : ViewCell
{
public CustomCell()
{
//instantiate each of our views
var image = new Image();
var nameLabel = new Label();
var typeLabel = new Label();
var verticaLayout = new StackLayout();
var horizontalLayout = new StackLayout() { BackgroundColor = Color.Transparent };
//set bindings
nameLabel.SetBinding(Label.TextProperty, new Binding("Name"));
image.SetBinding(Image.SourceProperty, new Binding("Image"));
//Set properties for desired design
horizontalLayout.Orientation = StackOrientation.Horizontal;
horizontalLayout.HorizontalOptions = LayoutOptions.Center;
image.HorizontalOptions = LayoutOptions.End;
nameLabel.FontSize = 24;
//add views to the view hierarchy
verticaLayout.Children.Add(nameLabel);
horizontalLayout.Children.Add(verticaLayout);
horizontalLayout.Children.Add(image);
// add to parent view
View = horizontalLayout;
}
}
what I tried already that gave the error
//ListView listView = new ListView();
//listView.RowHeight = 60;
//listView.ItemTemplate = new DataTemplate(typeof(CustomNocCell));
////listView.ItemsSource = "ImagesNoc";
//listView.SetBinding(ListView.ItemsSourceProperty, "ImagesList");
ImagesList class
[Ignore]
public ListView ImagesList
{
get
{
ListView listView = new ListView();
listView.RowHeight = 60;
listView.ItemTemplate = new DataTemplate(typeof(CustomNocCell));
List<string> list = new List<string>();
if (!string.IsNullOrEmpty(Detail))
{
foreach (string str in Detail.Split(';'))
{
list.Add(str);
}
}
listView.ItemsSource = list.Select(s => new { Name = s, Image = s.ToLower() + ".png" }).ToList();
return listView;
}
}
I had the class also returning a simple List of type Name and Image that the CustomCell is waiting and nothing.
EDIT
public class TestObject
{
public string title { get; set; }
public string countries { get; set; }
}
void load()
{
List<TestObject> list = new List<TestObject>();
list.Add(new TestObject { title = "test1", countries = "esp,ita,prt" });
list.Add(new TestObject { title = "test2", countries = "esp,ita" });
list.Add(new TestObject { title = "test3", countries = "rus" });
var labelTitle = new Label()
{
FontSize = Device.GetNamedSize(NamedSize.Small, typeof(Label)),
VerticalOptions = LayoutOptions.StartAndExpand,
};
listdata = new ListView();
listdata.ItemsSource = list;
var cell = new DataTemplate(() => {
var grid = new Grid() { Padding = 8, RowSpacing = 5, ColumnSpacing = 5 };
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Auto) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Auto) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Auto) });
labelTitle.SetBinding(Label.TextProperty, "title");
countriesLabel.SetBinding(Label.TextProperty, "countries"); //here i want to make a customcell to show the images, like be able to "bind" and calc the countries split the string by "," and add (name + ".png") then show the image.
// i was able to do it in a listview when i have the source in my side.. in this one i have to bind and then calc..
grid.Children.Add(labelTitle, 0, 0);
grid.Children.Add(countriesLabel, 1, 0);
});
listdata.ItemTemplate = cell;
}

Pls help me. Thanks in advance

The documentation for PatternFill (section 18.8.32 of the ECMA-376 standard) says (emphasis mine):
For solid cell fills (no
pattern), fgColor is used. For cell fills with patterns specified, then the cell fill color is specified by the bgColor
element.
You have specified PatternType = PatternValues.Solid but you are providing a BackgroundColor rather than a ForegroundColor. Changing from the BackgroundColor to the ForegroundColor will solve your issue i.e. this line:
new BackgroundColor() { Rgb = new HexBinaryValue(){ Value = "808080" } }
should become:
new ForegroundColor() { Rgb = new HexBinaryValue() { Value = "808080" } }

Xamarin forms RelativeLayout not appearing

I am following some pretty standard Xamarin forms tutorials and I am really struggling to get the RelativeLayout to work. Ultimately I want to have an ActivityIndicator overlaid on top of the mainContent:
BindingContext = new LoginViewModel(this);
Padding = new Thickness(20);
Title = "Login";
var image = new Image
{
Source = ImageSource.FromFile("logo.png"),
HeightRequest = 50
};
var label = new Label
{
Text = "...",
FontSize = 20,
HorizontalTextAlignment = TextAlignment.Center
};
var errorLabel = new Label
{
Text = "",
TextColor = Color.Red,
FontSize = 20,
HorizontalTextAlignment = TextAlignment.Center
};
var loginButton = new Button
{
Text = "Log In",
BackgroundColor = Color.Black,
TextColor = Color.White,
FontSize = 20,
HeightRequest = 50
};
var loginEntry = new Entry
{
Placeholder = "Username"
};
var passwordEntry = new Entry
{
Placeholder = "Password"
};
var copywrite = new Label
{
Text = "© 2016",
FontSize = 15,
HorizontalTextAlignment = TextAlignment.Center
};
var loadingIndicator = new ActivityIndicator
{
BackgroundColor = Color.Blue,
IsVisible = true
};
...
var topLayer = new StackLayout
{
Spacing = 10,
Children = { image, label, loginEntry, passwordEntry, loginButton, errorLabel },
VerticalOptions = LayoutOptions.Start
};
var bottomLayer = new StackLayout
{
Spacing = 10,
Children = { copywrite },
VerticalOptions = LayoutOptions.End
};
var mainContent = new StackLayout
{
Children =
{
topLayer,
new StackLayout
{
VerticalOptions = LayoutOptions.CenterAndExpand,
},
bottomLayer
},
VerticalOptions = LayoutOptions.FillAndExpand,
BackgroundColor = Color.Green
};
var r = new RelativeLayout()
{
BackgroundColor = Color.Pink
};
r.Children.Add(mainContent,
Constraint.RelativeToParent((parent) =>
{
return parent.Width;
}),
Constraint.RelativeToParent((parent) =>
{
return parent.Height;
})
);
Content = r;
When I set Content = mainContent I see everything fine, but with the above code I get a white screen. I have been looking here.
When I try this:
var overlay = new AbsoluteLayout()
{
BackgroundColor = Color.Pink
};
AbsoluteLayout.SetLayoutFlags(mainContent, AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(mainContent, new Rectangle(0f, 0f, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));
AbsoluteLayout.SetLayoutFlags(loadingIndicator, AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(loadingIndicator, new Rectangle(0.5, 0.5, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));
overlay.Children.Add(mainContent);
overlay.Children.Add(loadingIndicator);
Content = overlay;
I can see the Green and Pink views, but they may as well be stacked (as opposed to being overlaid) - but also I cannot see the Activity Indicator inside the Pink Absolute layout.

For the RelativeLayout, the Add method you are calling is setting a constraint on X and Y, not on width and height. The order of the parameters for that variant of Add is:
Child View
X constraint
Y constraint
Width constraint
Height constraint
With all constraints being optional.
To explicitly place it over the entire screen, do something like this:
r.Children.Add(mainContent,
Constraint.Constant(0),
Constraint.Constant(0),
Constraint.RelativeToParent((parent) =>
{
return parent.Width;
}),
Constraint.RelativeToParent((parent) =>
{
return parent.Height;
})
);
For the AbsoluteLayout, try a slightly different set of constraints:
AbsoluteLayout.SetLayoutFlags(mainContent, AbsoluteLayoutFlags.All);
AbsoluteLayout.SetLayoutBounds(mainContent, new Rectangle(0f, 0f, 1f, 1f));
This explicitly specifies that mainContent is to occupy the entire AbsoluteLayout rather than relying on the actual layout size of mainContent.

How to chart using Web.UI.DataVisualization.Charting?

using System.Web.UI.DataVisualization.Charting.Chart
I have data in 2 formats:
A.
B.
The data in format A is what I am using to build a chart. But my chart ends up looking like:
I cannot figure out how come no lines are drawn. Here is the code I am using:
var dataTable = GetDataTable();
var xAxisTitle = dataTable.Columns[1].ExtendedProperties["Type"].ToString();
var yAxisTitle = dataTable.Columns[0].ExtendedProperties["Type"].ToString();
chart = new Chart() {
AntiAliasing = AntiAliasingStyles.All,
TextAntiAliasingQuality = TextAntiAliasingQuality.High,
Width = 1200,
Height = 800,
Enabled = true,
ForeColor = Color.SaddleBrown
};
var chartArea = new ChartArea() {
BackColor = Color.White,
AxisY = new Axis() {
Enabled = AxisEnabled.True,
Title = yAxisTitle,
LineColor = Color.DarkBlue,
MajorTickMark = new TickMark() {
Enabled = true,
LineColor = Color.DarkGreen,
Interval = .1d
},
MinorTickMark = new TickMark() {
Enabled = true,
LineColor = Color.Green,
Interval = .1d
},
LabelStyle = new LabelStyle() {
Enabled = true,
ForeColor = Color.Red,
IsEndLabelVisible = true,
Font = new Font("Calibri", 4, FontStyle.Regular)
},
MajorGrid = new Grid() {
Enabled = true,
LineColor = Color.LightGray,
LineWidth = 1
},
},
AxisX = new Axis() {
Enabled = AxisEnabled.True,
Title = xAxisTitle,
LineColor = Color.DarkBlue,
MajorTickMark = new TickMark() {
Enabled = true,
LineColor = Color.Red,
Interval = .1d
},
MinorTickMark = new TickMark() {
Enabled = true,
LineColor = Color.DarkGreen,
Interval = .1d
},
LabelStyle = new LabelStyle() {
Enabled = true,
ForeColor = Color.Blue,
IsEndLabelVisible = true,
Font = new Font("Calibri", 4, FontStyle.Regular)
},
MajorGrid = new Grid() {
Enabled = true,
LineColor = Color.DarkGray,
LineWidth = 1
},
},
};
chartArea.AxisX.Enabled = AxisEnabled.True;
chartArea.AxisY.Enabled = AxisEnabled.True;
chart.ChartAreas.Add(chartArea);
var lineHeaders = dataTable.Rows
.OfType<DataRow>()
.Select(r => r[0].ToString())
.ToArray();
var i = 0;
for (int column = 0; column < lineHeaders.Length; column++) {
var header = lineHeaders[column];
var series = chart.Series[header] = new Series() {
Enabled = true,
Name = header,
Font = new Font("Lucida Sans Unicode", 6f),
Color = legendColors[header],
ChartType = SeriesChartType.Line,
XValueType = ChartValueType.DateTime,
YValueType = ChartValueType.Double,
};
var colData = dataTable.Rows[column]
.ItemArray
.Skip(1)
.Select(d => (double)d)
.ToArray();
DataPoint p = new DataPoint() {
AxisLabel = header,
XValue = i++,
YValues = colData,
};
series.Points.Add(p);
}
I've also set the data table as the data source on the Chart but there are no data points plotted.
Am I even using the correct data table ...should I be using format B instead?

I proceeded with the table format option B:
Other codes changes were minimal but re-posting the entire snippet below. The primary fix are these two lines at the end of the method:

chart.DataBind();
