What Properties must I set to get this result? (Palette)

[wschrabi]

Dear friend,
Can someone tell me, what Palette Properties must I set to get this Result. I tried the UsePalette but I always get not this Rainbow style but a graduating color style. Here is the wanted result - captured from the demo.

Ok, friends I found it out. But when you see my pic ()you can see that the legend shows the wanted rainbow-style pallete but the data dont look like in the first pic. It loks aweful. How must I define the data, that I can get an result like in the wanted first example?

Here my wrong result.

Hi wschrabi,

It seems to me that you need to add more values to your series, try something like this:

Code: Select all

  Series1.FillSampleValues(50);
  Series1.Pen.Visible:=false;

  Chart1.Chart3DPercent:=100;

Hi Narcis,
thanks yes now I can see it as wanted. But I do not understand why the color is red on that points where I draw the green arrow?
It does not fit to the legend.
HAve you an idea?
Thanks

PS: I think it has something to do with PaletteSteps := 40; because when I use PaletteSteps := 20; then the color fits to the legend. Can you explain this?

Hi wschrabi,

Yes, exactly. RainbowPalette has 25 colours. If NumSteps is set to a bigger number it repeats colours as you have experienced.

You can avoid this enabling "Use palette minimum" checkbox:

Code: Select all

  Series1.UsePaletteMin:=true;

Thanks a lot, now the secret is disclosed.
