Creat LineSeries with ColorGridSeries Y Values?

[cfalcot]

Hi,

I have a TColorGridSeries (named Series10 - affected with ChartTool5) and a TLineSeries(named Series1). I would like use the X and Z value to draw the LineSeries.

Is it possible to do somthing like this(?):

Code: Select all

For i:= 1 to 10 do
  Series1.AddXY(Series10.GetXZValue(ChartTool5.XValue, i), i);

Unfortunaty this not work: all Values are null. In helpfiles I find that GetXZValue returns zero if OnGetYValue is not assigned. What OnGetYValue need to be assigned on: I don't find.

Thank's for your help...

Hi Cyril,

the GetXZValue does not return value for specific index. This event can be used only for constructing the surface from formula. i.e. you have to specify y=y(x,z) -> in this case the GetXZValue will return y for specific x and z.
If you simply populate series with data (not by specifying a function) the GetXZValue will not work i.e. it will always return 0 (or -1?).
There is an example of this method in the Demo Features project under the "All Features -> Chart styles -> Extended ", the "Surface" (first) example. To get the YValues of the ColorGrid Series you can use :
TColorGridSeries.Value[x,z]
