stacked bar issue with .net6

Hello Christopher

I want to use checkbox for legend,
I can't see the checkbox in the legend.

And if I remove the annotation and bar1 and bar2 have the 0th value, it works well.
However, when there is no 0th value, there is a problem with the 0th bar position, and there is a problem with the sort of the 2nd bar.
Is this a bug?
Please check it.

Code: Select all

public Form1()
    {
      InitializeComponent();
      InitializeChart();
    }

    private Steema.TeeChart.Styles.Bar bar1;
    private Steema.TeeChart.Styles.Bar bar2;
    private Steema.TeeChart.Styles.Bar bar3;

    private void InitializeChart()
    {
      this.bar1 = new Steema.TeeChart.Styles.Bar();
      this.bar2 = new Steema.TeeChart.Styles.Bar();
      this.bar3 = new Steema.TeeChart.Styles.Bar();

     this.bar1.Brush.Color = Color.Red;
     this.bar1.Title = "bar1";
     this.bar1.XValues.DataMember = "X";
     this.bar1.YValues.DataMember = "Bar";
     this.bar1.Marks.Visible = false;

     this.bar2.Brush.Color = Color.Green;
     this.bar2.Title = "bar2";
     this.bar2.XValues.DataMember = "X";
     this.bar2.YValues.DataMember = "Bar";
     this.bar2.Marks.Visible = false;

     this.bar3.Brush.Color = Color.Blue;
     this.bar3.Title = "bar3";
     this.bar3.XValues.DataMember = "X";
     this.bar3.YValues.DataMember = "Bar";
     this.bar3.Marks.Visible = false;

     this.tChart1.Series.Add(this.bar1);
     this.tChart1.Series.Add(this.bar2);
     this.tChart1.Series.Add(this.bar3);

     bar1.MultiBar = Steema.Teechart.Styles.MultiBars.Stacked;

     //bar1.Add(0,0);
     bar1.Add(1,100);
     bar1.Add(2,100);
     
     //bar2.Add(0,0);
     bar2.Add(1,90);
     bar2.Add(2,90);
     
     bar3.Add(0,70);
     bar3.Add(1,70);
     bar3.Add(2,70);

     tChart1.Legend.CheckBoxes = true;

      var assembly = Assembly.GetAssembly(typeof(TChart));
      var fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);

      tChart1.Header.Text += $" version {fvi.FileVersion}";
    }

Hello,

I want to use checkbox for legend,
I can't see the checkbox in the legend.

This is because we used the ControlPaint class to draw the checkboxes in .NET Framework, but unfortunately this class doesn't exist in .NET 5.0/6.0. You will have to add in a Windows Form checkbox manually and use that, I'm afraid (with Legend.CheckBoxes set to false).

And if I remove the annotation and bar1 and bar2 have the 0th value, it works well.
However, when there is no 0th value, there is a problem with the 0th bar position, and there is a problem with the sort of the 2nd bar.
Is this a bug?

This hasn't changed between the thirteen year-old version:

All right. I see.
I think the chart problem will be solved by adding the 0th value.
However, it is a problem that the check box is not available in Legend.
Thanks anyway.
