I have an application with Chart control that dynamic updated with data via timer:
Series series;
MyObject obj...
series = new Series();
chart1.Series.Add(series);
//chart1.Legends.Add(new Legend("DifferentLegend"));
//chart1.Legends["DifferentLegend"].DockedToChartArea = "Default";
//chart1.Series["Series1"].Legend = "DifferentLegend";
//chart1.Series["Series1"].IsVisibleInLegend = true;
series.Color = Color.Blue;
series.ChartType = SeriesChartType.Line;
series.BorderWidth = 3;
chart1.Series.Add(series);
//chart1.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.White;
//chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.White;
chart1.ChartAreas[0].AxisX.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisY.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisX.Maximum = 4;
chart1.ChartAreas[0].AxisX.Interval = 1;
chart1.ChartAreas[0].AxisX.IsStartedFromZero = true;
chart1.ChartAreas[0].AxisX.IntervalOffsetType = DateTimeIntervalType.Number;
Timer tick:
private void chartTimer_Tick(object sender, EventArgs e)
{
series.Points.Add(obj.BitsPerSecond * 0.000001);
}
I want to change it style and remove the squares from the control:
How can I do that?
Try This:
chart1.ChartAreas[0].AxisX.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisX.MinorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisY.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisY.MinorGrid.LineWidth = 0;
To disable X-Axis Labels from the Chart :
chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = false;
This then?
mainChart.ChartAreas[0].AxisX.MajorGrid.Enabled = false;
mainChart.ChartAreas[0].AxisY.MajorGrid.Enabled = false;
mainChart.ChartAreas[0].AxisX.MinorGrid.Enabled = false;
mainChart.ChartAreas[0].AxisY.MinorGrid.Enabled = false;

I am trying to set up a column graph with the time. Why is my graph not showing up on the main window?
I initialized the graph object like this :
private Chart graph = new Chart();
my chart functions are:
private void DrawTimeChart(string testName,double time)
{
Series sinSeries = new Series();
sinSeries.ChartType = SeriesChartType.Column;
sinSeries.Color = System.Drawing.Color.Blue;
sinSeries.BorderWidth = 2;
sinSeries.Points.AddXY(testName,time);
}
private void cnvChart_Loaded(object sender, RoutedEventArgs e)
{
System.Windows.Forms.Integration.WindowsFormsHost host = new System.Windows.Forms.Integration.WindowsFormsHost();
graph.Width = 250;
graph.Height = 250;
host.Child = graph;
// Add the chart to the canvas so it can be displayed.
this.cnvChart.Children.Add(host);
}
private void SetUpChart(Chart funcChart, int marginX, int marginY)
{
graph.Series.Clear();
graph.ChartAreas.Clear();
graph.ChartAreas.Add("Default" + new Random());
// Add a series with some data points.
funcChart.Width = 349;
funcChart.Height = 177;
funcChart.Location = new System.Drawing.Point(marginX, marginY);
funcChart.ChartAreas[0].AxisX.Title = "X";
funcChart.ChartAreas[0].AxisX.Interval = 1.0;
funcChart.ChartAreas[0].AxisX.Crossing = 0;
funcChart.ChartAreas[0].AxisX.LabelStyle.Format = "{0.0}";
funcChart.ChartAreas[0].AxisX.MajorGrid.LineWidth = 0;
funcChart.ChartAreas[0].AxisY.Title = "Y";
funcChart.ChartAreas[0].AxisY.Interval = 1.0;
funcChart.ChartAreas[0].AxisY.Crossing = 0;
funcChart.ChartAreas[0].AxisY.LabelStyle.Format = "{0.0}";
funcChart.ChartAreas[0].AxisY.MajorGrid.LineWidth = 0;
funcChart.ChartAreas[0].AxisX.Maximum = 6;
funcChart.ChartAreas[0].AxisX.Minimum = -6;
funcChart.ChartAreas[0].AxisY.Maximum = 7;
funcChart.ChartAreas[0].AxisY.Minimum = -7;
}
I'm calling the functions like this:
SetUpChart(graph,5,5);
DrawTimeChart("test1",time1);
in regards to XAML, that's how my canvas is written:
<Canvas x:Name="cnvChart" HorizontalAlignment="Right" Height="177"
Margin="0,242,392.333,0" VerticalAlignment="Top" Width="349"
Loaded="cnvChart_Loaded" RenderTransformOrigin="0.5,0.5"/>
I have a panel in Visual Studio/windows form app.But I coulnd't add pictureBox on it with code.It is working if I work without panel however I need it.MyCodes:
PictureBox[] pipe = new PictureBox[3];
private void Form1_Load(object sender, EventArgs e)
{
CreatePipes(1);}
private void CreatetopPipes(int Number)
{
for (int i = 0; i <= Number; i++)
{
PictureBox temp = new PictureBox();
this.Controls.Add(temp);
temp.Width = 50;
temp.Height = 350;
temp.BorderStyle = BorderStyle.FixedSingle;
temp.BackColor = Color.Red;
temp.Top = 30;
temp.Left = 300;
topPipe[i] = temp;
topPipe[i].Visible = true;
}
}
You can use panelName.Controls.Add(temp), and i advise you to change a top of PictureBox in for loop to view all PictureBox, like this :
private void CreatetopPipes(int Number)
{
for (int i = 0; i <= Number; i++)
{
PictureBox temp = new PictureBox();
panelName.Controls.Add(temp);
temp.Width = 50;
temp.Height = 350;
temp.BorderStyle = BorderStyle.FixedSingle;
temp.BackColor = Color.Red;
temp.Top = temp.Height * panelName.Controls.Count;
temp.Left = 300;
topPipe[i] = temp;
topPipe[i].Visible = true;
}
}
I have a C# program that reads in data from an Arduino Mega four times a second and displays the data in two charts, each chart has two sets of data. After a couple of hours of running the data starts to lag. I can watch the program grow in size over time. I believe the problem is the charts are showing snapshot of 1 minute on each chart but the program just keeps collecting data and creating the memory leak issue. Is there a way to limit the data collection to a minute or two and dump the old data?
This is my first C# program I have ever written and I'm an old fart (62) and suffer from CRS "Can't Remember Sh_t".
Any help would be greatly appreciated.

I have 2 bar series in a tee chart. One is a percent value between 0 and 100 and uses the left axis. The other is a temperature, uses the right axis, and the range of possible values is between -40F and 160F.
I would like both bars to start at the bottom axis. I thought that the UseOrigin and Origin properties of the series would do this but apparently it doesn't work.
Below is my code:
chartTank = new TChart();
chartTank.Axes.Left.Grid.Visible = false;
chartTank.Axes.Right.Grid.Visible = false;
chartTank.Axes.Right.Maximum = 160.0;
chartTank.Axes.Right.Minimum = -40;
chartTank.Axes.Right.Increment = 40;
chartTank.Axes.Right.Automatic = false;
chartTank.Axes.Right.AutomaticMinimum = false;
chartTank.Axes.Right.AutomaticMaximum = false;
chartTank.Aspect.View3D = false;
chartTank.Panel.Bevel.Inner = Steema.TeeChart.Drawing.BevelStyles.None;
chartTank.Panel.Bevel.Outer = Steema.TeeChart.Drawing.BevelStyles.None;
chartTank.Axes.Left.Grid.Visible = false;
chartTank.Axes.Bottom.GridCentered = false;
chartTank.Axes.Bottom.Ticks.Visible = false;
chartTank.Axes.Left.Automatic = false;
chartTank.Axes.Left.Minimum = 0;
chartTank.Axes.Left.Maximum = 100;
chartTank.Axes.Right.Visible = true;
var barProduct = new Steema.TeeChart.Styles.Bar();
barProduct.MultiBar = MultiBars.Stacked;
barProduct.Color = Color.Green;
barProduct.Marks.Visible = false;
barProduct.Title = "% Vol";
barProduct.ShowInLegend = true;
chartTank.Series.Add(barProduct);
var barTemperature = new Steema.TeeChart.Styles.Bar();
barTemperature.MultiBar = MultiBars.None;
barTemperature.Color = Color.FromArgb(153, 74, 11);
barTemperature.Marks.Visible = false;
barTemperature.VertAxis = VerticalAxis.Right;
barTemperature.UseOrigin = true;
barTemperature.Origin = -40;
barTemperature.Title = "Temperature";
barTemperature.ShowInLegend = true;
chartTank.Series.Add(barTemperature);
Controls.Add(chartTank);
Here is the result:
