line series with different style

Hello,
is it possible to have different line styles (e.g. dash and solid) on the very same series?
What I'm trying to do is to code additional infomation (data is trustworthy or not) using the line style.
Different colors would be no solutions since there are several lines in one chart.
Hopefully you have an idea,
Marcus

Hello schafma,
is it possible to have different line styles (e.g. dash and solid) on the very same series?
Is not possible have different line styles for one series. I recommend that do something as next code:
Code: Select all
private Steema.TeeChart.Styles.Line line, line1;
private void Form1_Load(object sender, EventArgs e)
{
line = new Steema.TeeChart.Styles.Line(tChart1.Chart);
line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
tChart1.Aspect.View3D = false;
line.FillSampleValues(10);
line1.FillSampleValues(5);
for (int i = 0; i <= (line.Count)/2; i++)
{
line1[i].X = line[i].X;
line1[i].Y = line[i].Y;
}
line.LinePen.Style = System.Drawing.Drawing2D.DashStyle.Dash;
line.LinePen.Width = 3;
line1.LinePen.Style = System.Drawing.Drawing2D.DashStyle.Solid;
line1.LinePen.Width = 3;
line1.Color = line.Color;
}
Please, check next code works if you want.
I hope will helps.
Thanks,

Dear Sandra,
thank you for the idea. I'm not quite sure if this solution is flexible enough for my needs but I'll give it a try.
I had also the idea to use the colors arrays of the line series to assign different alpha values (opacities) to the according line segments.
Once again thank you for your help.
Maybe this feature (different line styles per line segment) will be implemented in a futur release.

Hi Marcus,
Here it is another possibility, maybe more flexible (you could have an array of segments in the line to be discontinuous and check it in the condition into the GetPointerStyle event)
Code: Select all
Steema.TeeChart.Styles.Line line;
private void InitializeChart()
{
line = new Steema.TeeChart.Styles.Line(tChart1.Chart);
tChart1.Aspect.View3D = false;
line.FillSampleValues(10);
line.LinePen.Width = 3;
line.Pointer.Visible = true;
line.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(line_GetPointerStyle);
}
void line_GetPointerStyle(Steema.TeeChart.Styles.CustomPoint series, Steema.TeeChart.Styles.GetPointerStyleEventArgs e)
{
if ((e.ValueIndex == 3) || (e.ValueIndex == 6)) line.LinePen.Style = System.Drawing.Drawing2D.DashStyle.Dash;
else line.LinePen.Style = System.Drawing.Drawing2D.DashStyle.Solid;
e.Style = Steema.TeeChart.Styles.PointerStyles.Nothing;
}
