I am using the popular method of searching line coordinates to get the index. If you know of an easier method let me know?

How do I get the index of the currently selected line? For example, I have several lines using Drawline array: Dim I1() As Steema.TeeChart.Tools.DrawLineItem DrawLine5.Pen.Color = DefaultColor2 'Drawing.Color.Gray DrawLine5.Pen.Width = 1 DrawLine5.Active = True DrawLine5.EnableSelect = True DrawLine...

I think I know how to do it...Put the drawline code in the afterdraw event of Teechart and use screen coordinates to draw the lines.. It was in the tutorial.

I want to be able to annotate a 3D chart with simple drawing tools using screen coordinates.

Use drawline tool to draw polygon shapes. I can only find lines, boxes and ellipses.

If I draw a Line on a 3D Chart with the Drawline Tool, the default position is 3D Coordinates. Is it possible to change the default drawing position to 2D Coordinates, so the line is always drawn at the mouse position, without having to consider 3D rotation of the chart?

Hi,

I would like to see polygons added to drawlinestyle of the drawline tool.

With the points series, is there a property to allow/disallow duplicate data.

If I have two or more rows of data exactly the same, how will this affect plotting the chart?

Hi, Thanks, I looked at that thread. I am adding the data correctly, that is not the problem. If I add values with Very Different Axes Scales, Isolines are plotted, but the color fill is not plotted. If I use this code: For x = 0 To 10 For z = 100 To 500 Step 100 .Add(x, Rnd(), z) Next z Next x Fill...

The code works OK.

If I use my data in the activex version, it plots OK. I also grid the data first to get an evenly spaced grid. The problem occurs if I use different scale for left and bottom axes.

If I set FillLevels=True on a Contour Series, it should plot filled color contours. For certain types of data, this will not work for me: X Y Z 26070 46750 4.6750 27890 37640 3.7640 31640 36960 4.1 18800 41300 2.1230 24725 43400 4.3400 25060 36030 3.6030 27310 40360 4.0360 21110 50890 5.0890 23450 4...

Got the original code working. Just had to activate and relate the charts in the editor.

Thanks,

Just a thought - I could add PolyFitting1.AddPoints method to the code.

What is the correct format for array Addpoints - there is no detailed reference in the documentation

Should I add an array of X Values or X and Y Values?

How should the Array be Declared?

Thanks,

Thanks Sandra, I am using the example code but the coefficients keep returning 0. PolyFitting1.PolyDegree = 2 Points1.DataSource = Points1 PolyFitting1.Chart = TChart1.Chart Points1.Function = PolyFitting1 Points1.Function.Period = 2 Points1.CheckDataSource() Points1.Function.Calculate(TChart1.Serie...

I found the solution by using

'Draw Pattern Fill
Dim br2 As New Drawing2D.HatchBrush(CType(FillPat2, Drawing2D.HatchStyle), Drawing.Color.Black, Drawing.Color.White)
g.FillRectangle(br2, point1.X , point1.Y, RECT_WID2 , RECT_HGT2)


Thanks,
