GroupBy bool and Select values for new list

I am trying to get into more complex Linq queries and right away catch a point I am feeling stuck. I have a following list in DB:
ID ELAPSED TIME APPISRUNNING
1 12 TRUE
2 54 TRUE
3 32 FALSE
Where ELAPSED TIME is TimeSpan and APPISRUNNING is a bool.
I would like to build a chart based on these values (https://github.com/beto-rodriguez/LiveCharts2). Chart build fine with this:
Title = "Analytics";
this.ActivityChartSeries = new ISeries[]
{
new PieSeries<double> { Values = new double[] { 2 }},
new PieSeries<double> { Values = new double[] { 2 }},
new PieSeries<double> { Values = new double[] { 2 }},
new PieSeries<double> { Values = new double[] { 2 }},
new PieSeries<double> { Values = new double[] { 2 }},
};
Now I somehow need to first GroupBy bool and then select a new List? I have tried following:
IEnumerable<DataRecord> dataRecords = await this.DataStore.GetItemsAsync();
this.ActivityChartSeries = dataRecords
.GroupBy(g => g.AppIsRunning)
.Select(m => new
{ // BELOW IS TOTALLY UNCLEAR FOR ME
Values = m.Select(r => r.EngineElapsed.Ticks),
Name = m.Select(r => r.Name),
})
.Select(x =>
new PieSeries<double>
{
Values = new List<double> { x.Values.FirstOrDefault() },
Name = x.Name.FirstOrDefault(),
});
Type of assigned variable:
public IEnumerable<ISeries> ActivityChartSeries
This part is totally unclear for me:
Values = m.Select(r => r.EngineElapsed.Ticks),
Name = m.Select(r => r.Name),
How after GroupBy I can create two types of data? Basically I need
"Application Running" and "Values"
"Application is not Running" and "Values"
EDIT:
Code provided by Somar Zein compiles fine:
var results = activityChartSeries
.GroupBy(a=> a.AppIsRunning)
.Select(item=> new PieSeries<double>{
Name = item.Key ? "Application is Running" : "Application is not Running",
Values = item.Select(x=> Convert.ToDouble(x.ElapsedTime.Ticks)).ToList()
});
However as a result I am getting something like this, why it is reloading in a loop?
Here is result:
enter image description here
EDIT2:
So I have created an example for testing purposes:
Class:
public class DataModel
{
public int Id { get; set; }
public TimeSpan ElapsedTime { get; set; }
public bool AppIsRunning { get; set; }
}
Code:
List<DataModel> records = new List<DataModel>();
records.Add(new DataModel { Id = 1, ElapsedTime = new TimeSpan(1, 20, 30), AppIsRunning = true });
records.Add(new DataModel { Id = 2, ElapsedTime = new TimeSpan(1, 20, 30), AppIsRunning = true });
records.Add(new DataModel { Id = 3, ElapsedTime = new TimeSpan(1, 20, 30), AppIsRunning = true });
records.Add(new DataModel { Id = 4, ElapsedTime = new TimeSpan(1, 20, 30), AppIsRunning = true });
records.Add(new DataModel { Id = 5, ElapsedTime = new TimeSpan(1, 20, 30), AppIsRunning = true });
this.ActivityChartSeries = records
.GroupBy(g => g.AppIsRunning)
.Select(item => new PieSeries<double>
{
Name = item.Key ? "Running" : "Not Running",
Values = new double[] { 2, 4 },
});
I get the same reloading effect, even thou originally provided Example from LiveCharts work fine.

you could try doing something like following:
var results = activityChartSeries
.GroupBy(a=> a.AppIsRunning)
.Select(item=> new PieSeries<double>{
Name = item.Key ? "Application is Running" : "Application is not Running",
Values = item.Select(x=> Convert.ToDouble(x.ElapsedTime.Ticks)).ToList()
});
hope that could be helpful!

WPF Pie Chart how to add space between slices?

I am using Telerik (RadPieChart) with WPF. How can I add space between the slices ?
This is what I currently have:
And this is how I want my Pie chart to look like with the spaces between the slices:
Here is my source code:
private DoughnutSeries CreateDognutSerie(KeyValuePair<ChartSerie, List<ChartDataPoint>> chartSerie, int index, int count)
{
double spaceBetweenSperies = 0.0;
if (count > 1 && index != count - 1)
{
spaceBetweenSperies = 0.007;
}
var doughnutSerie = new DoughnutSeries()
{
ShowLabels = true,
//LabelConnectorsSettings = new ChartSeriesLabelConnectorsSettings()
//{
//},
InnerRadiusFactor = index / (double)count,
RadiusFactor = ((index + 1) / (double)count) - spaceBetweenSperies,
//LegendSettings = new DataPointLegendSettings()
//{
//},
//SeriesAnimation = new PieChartAngleRangeAnimation()
//{
// InitialStartAngle = -90,
// InitialSweepAngle = 180,
// Duration = new TimeSpan(0, 0, 0, 0, 800),
//}
};
foreach (ChartDataPoint serie in chartSerie.Value)
{
doughnutSerie.DataPoints.Add(new PieDataPoint()
{
Label = serie.XPoint.Label,
Value = Math.Abs((double?)serie.Value ?? 0),
});
}
return doughnutSerie;
}

Use the OffsetFromCenter property in PieDataPoint. Something like OffsetFromCenter = 0.015 should be similar to the above image.
public MainWindow()
{
InitializeComponent();
var data = new Dictionary<string, double>
{
{ "January", 5 },
{ "February", 3 },
{ "March", 5 },
{ "April", 7 },
{ "May", 2 },
{ "June", 11 },
{ "July", 11 },
{ "August", 11 },
{ "September", 11 },
{ "October", 11 },
{ "November", 11 },
{ "December", 12 },
};
var series = CreateDougnutSeries(data);
var pie = new RadPieChart { Palette = ChartPalettes.Fluent };
pie.Series.Add(series);
mainGrid.Children.Add(pie);
}
private DoughnutSeries CreateDougnutSeries(Dictionary<string, double> data)
{
var doughnutSeries = new DoughnutSeries
{
ShowLabels = true,
InnerRadiusFactor = 0,
RadiusFactor = 1
};
foreach (var point in data)
{
doughnutSeries.DataPoints.Add(new PieDataPoint()
{
Label = point.Key,
Value = point.Value,
OffsetFromCenter = 0.015
});
}
return doughnutSeries;
}
Increasing OffsetFromCenter to say 0.1 will render thicker lines:

Here is an example the produces a Chart graphic just like the one in the linked image.
Note: After I have created a few testdata I calculate a dummy series with a transparent color that will make the whole data stack up so that the median of the "neutral" series sits nicely on one horizontal line.
int numPoints = 30; // create some test data
List<int> neutralData = new List<int>();
List<int> negativeData = new List<int>();
List<int> positiveData = new List<int>();
List<int> dummyData = new List<int>();
for (int i = 0; i < numPoints; i++)
{
// the real data series, using a Random R:
positiveData.Add(R.Next(i + 22));
neutralData .Add(R.Next(i + 33));
negativeData.Add(R.Next(i + 44));
// calculate the transparent bottom series:
dummyData.Add( - neutralData[i] / 2 - negativeData[i]);
}
// set up the Chart:
chart1.ChartAreas.Add("StackedArea"); // if necessary
Series s0 = chart1.Series.Add(" ");
Series s1 = chart1.Series.Add("negative");
Series s2 = chart1.Series.Add("neutral");
Series s3 = chart1.Series.Add("positive");
foreach (Series s in chart1.Series) s.ChartType = SeriesChartType.StackedArea;
s0.Color = Color.Transparent;
s1.Color = Color.FromArgb(200, Color.Red);
s2.Color = Color.FromArgb(200, Color.LightSlateGray);
s3.Color = Color.FromArgb(200, Color.Green)
// now add the data points:
for (int i = 0; i < numPoints; i++)
{
s0.Points.AddXY(i, dummyData[i]);
s1.Points.AddXY(i, negativeData[i] );
s2.Points.AddXY(i, neutralData [i]);
s3.Points.AddXY(i, positiveData[i]);
}
If you want to show a tooltip similar to the one from your example you can add this to the AddXY loop:
int a2 = dummyData[i] + negativeData[i];
int a3 = a2 + neutralData[i];
int a4 = a3 + positiveData[i];
string tt = string.Format( "Data Point {0}\r\nPositive: {1} - {2}\r\n"
+ "Neutral: {2} - {3}\r\nNegative: {3} - {4}", i, a4, a3, a2, dummyData[i]);
s1.Points[i].ToolTip = tt;
s2.Points[i].ToolTip = tt;
s3.Points[i].ToolTip = tt;
Here is an example image:

You can not create a chart exactly like the one shown in link but you can use different series on your chart. I am posting the code that creates a chart and populates it with 2 series, you can add as many series as you want.
DataSet dataSet;
ConnectionClass.GetInstance().connection_string = Properties.Settings.Default.MindMuscleConnectionString;
ConnectionClass.GetInstance().Sql = "Select Count(MemberInfo.memberName) as 'Members', CompetitionName as 'Competition' FROM MemberInfo, MemberBodyInfo, Competition WHERE MemberInfo.memberID = MemberBodyInfo.memberID AND MemberBodyInfo.weight >= Competition.CompetitionCategory and MemberBodyInfo.weight <= Competition.CompetitionCategory + 5 group by CompetitionName;";
dataSet = ConnectionClass.GetInstance().GetConnection;
chart1.Series["Series1"].Name = "Members";
chart1.Series["Members"].YValueMembers = "Members";
chart1.Series["Members"].XValueMember = "Competition";
chart1.Series.Add("Members2");
chart1.Series["Members2"].ChartType = SeriesChartType.StackedArea;
chart1.Series["Members2"].IsValueShownAsLabel = true;
chart1.Series["Members2"].YValueMembers = "Members";
chart1.Series["Members2"].XValueMember = "Competition";
this.chart1.Titles.Add("Competition Participants"); // Set the chart title
chart1.Series["Members"].ChartType = SeriesChartType.StackedArea;
chart1.Series["Members"].IsValueShownAsLabel = true; // To show chart value
chart1.DataSource = dataSet;
chart1.DataBind();
I have not actually created a new series from some different data... Both series are same here but I have just showed you an example.

MVC 4 C# How to create a method that returns a list<object>

I am using EF and seeding our DB with some product data. The data with which I'm seeding has a part which will be repeated about 100 times. Rather than copy and paste my code I would rather populate my list with a method but as I am a newbie, I cannot seem to make this work properly:
Here is the code in context:
context.Products.AddOrUpdate(
pr => pr.Name,
new Product
{
Name = "3.5x5",
ProductCategoryId = 1,
ProductSubCategoryId1 = 1,
ProductSubCategoryId2 = 3,
VendorId = 1,
HeightUnitId = 2,
Height = (decimal)3.5,
Width = 5,
ProductOptions =
new List<ProductOption>
{
new ProductOption { Name = "Paper", InputTypeSingleOptionId = 1, InputTypeMultipleOptionId = 2, SortOrder = 1,
ProductOptionsDetails =
new List<ProductOptionsDetail>
{
new ProductOptionsDetail { Name = "Glossy", Value = "Glossy", IsDefault = true, SortOrder = 1 },
new ProductOptionsDetail { Name = "Matte", Value = "Matte", IsDefault = false, SortOrder = 2 },
new ProductOptionsDetail { Name = "Metallic", Value = "Metallic", IsDefault = false, SortOrder = 3 },
new ProductOptionsDetail { Name = "Lustre", Value = "Lustre", IsDefault = false, SortOrder = 4 }
}
},
new ProductOption { Name = "Color", InputTypeSingleOptionId = 1, InputTypeMultipleOptionId = 2, SortOrder = 2,
ProductOptionsDetails =
new List<ProductOptionsDetail>
{
new ProductOptionsDetail { Name = "Color", Value = "Color", IsDefault = true, SortOrder = 1 },
new ProductOptionsDetail { Name = "Black and white", Value = "Black and White", IsDefault = false, SortOrder = 2 },
new ProductOptionsDetail { Name = "Sepia", Value = "Sepia", IsDefault = false, SortOrder = 3 }
}
},
new ProductOption { Name = "Texture", InputTypeSingleOptionId = 1, InputTypeMultipleOptionId = 2, SortOrder = 3,
ProductOptionsDetails =
new List<ProductOptionsDetail>
{
new ProductOptionsDetail { Name = "None", Value = "None", IsDefault = true, SortOrder = 1 },
new ProductOptionsDetail { Name = "Linen texture", Value = "Linen", IsDefault = false, SortOrder = 2 },
new ProductOptionsDetail { Name = "Canvas texture", Value = "Canvas", IsDefault = false, SortOrder = 3 },
new ProductOptionsDetail { Name = "Watercolor texture", Value = "Canvas", IsDefault = false, SortOrder = 4 },
new ProductOptionsDetail { Name = "Pebble texture", Value = "Pebble", IsDefault = false, SortOrder = 5 }
}
},
new ProductOption { Name = "Coating", InputTypeSingleOptionId = 1, InputTypeMultipleOptionId = 2, SortOrder = 4,
ProductOptionsDetails =
new List<ProductOptionsDetail>
{
new ProductOptionsDetail { Name = "None", Value = "None", IsDefault = true, SortOrder = 1 },
new ProductOptionsDetail { Name = "Linen texture", Value = "Linen", IsDefault = false, SortOrder = 2 },
new ProductOptionsDetail { Name = "Canvas texture", Value = "Canvas", IsDefault = false, SortOrder = 3 },
new ProductOptionsDetail { Name = "Watercolor texture", Value = "Canvas", IsDefault = false, SortOrder = 4 },
new ProductOptionsDetail { Name = "Pebble texture", Value = "Pebble", IsDefault = false, SortOrder = 5 }
}
}
}
},
The part I would like to return from a method would be something like:
ProductOptions = getOptions() All that nested code can be repeated verbatim. I have tried working from some other examples but I keep on getting errors in Visual Studio. If I could get a very basic approach to this, that would be greatly appreciated.

public List<ProductOptionsDetail> GetOptions() {
return new List<ProductOptionsDetail>()
{
new ProductOptionsDetail() { Name = "None", Value = "None", IsDefault = true, SortOrder = 1 },
new ProductOptionsDetail() { Name = "Linen texture", Value = "Linen", IsDefault = false, SortOrder = 2 },
new ProductOptionsDetail() { Name = "Canvas texture", Value = "Canvas", IsDefault = false, SortOrder = 3 },
new ProductOptionsDetail() { Name = "Watercolor texture", Value = "Canvas", IsDefault = false, SortOrder = 4 },
new ProductOptionsDetail() { Name = "Pebble texture", Value = "Pebble", IsDefault = false, SortOrder = 5 }
};
}

xAxis : [{categories : []}], // when defining X-Axis
chart.xAxis[0].setCategories(JSON_object); // when parsing data ,from another method ,
if you want to use categories X-Axis or Y-Axis ? .bcoz the code and the chart image confusing me , any way if you want to set the categories by manually , then initially make categories as null , and assigned a array to it by using JQuery , if you loading dynamic data , then there should be a parsed json object or something semilar
