Hi!

I have a problem with "wrong/bad" colors in tSurfaceSeries.

I Use tSurfaceSeries.getColor to get a Color for each point of the graph.

The procedure is very simple:

Code: Select all

procedure TFGraph3D.Series1GetColor(Sender: TChartSeries;   ValueIndex: Integer; var Color: TColor);
begin
  color:=UseColorFkt(cMin,cMax,Series1.YValue[ValueIndex]);
end;

(UseColorFkt just returns a value/color in dependency of the input-value)

Lets start with 1st picture:

As you see the left and right sides (100% identical data) have not the
same colors! I think thats the problem of GetColor and using just 1 point
(Series1.YValue[ValueIndex]) in that function. But how to make it look okay?

2nd problem:

Here you see that hard changes in color.
What is wanted here is a smooth color that just depends of the height!

Of course i could "solve" that problems by inserting many pseudo-points -
but that costs memory and MUCH time when rendering. So just Adding
new points is not a real solution.

Better ideas?
(Idea ???: A perfect solution could ask me for every pixel for its color)

Thanks,

Hi Steffen,

Could you please send us a simple example we can run "as-is" to reproduce those issues here?

You can post your files at news://www.steema.net/steema.public.attachments newsgroup.

Thanks in advance.
