Hi Leonardo,

Yes - that's true - in this mode all individual settings for points are ignored as the resulting point is an approximation of serveral points.

I found the problem: enabling the cluster mode disables the fill style for each point.

Hi Leonardo,

That code is Ok - most likely you apply a chart palette later in the code that overrides the settings for color...

Why the following code does not work? if the X and Y are set, why not the other properties?

for (int i = 0; i < length; i++)
{
NDataPoint dataPoint = new NDataPoint();
NColor color = this.colorScale.GetColor(this.zLog[i]);
dataPoint[DataPointValue.Color] = color;
dataPoint[DataPointValue.FillStyle] = new NColorFillStyle(color);
dataPoint[DataPointValue.StrokeStyle] = new NStrokeStyle(1, color);
dataPoint[DataPointValue.Y] = this.yLog[i];
dataPoint[DataPointValue.X] = this.xLog[i];
series.AddDataPoint(dataPoint);
}

Just to clarify the question:

I have a 2D plot and want to add different colors to a third attribute, that can be the Z value or not. In the examples for Point chart (Standard Point example), it's possible to have different colors for each point, but based on the value property only in an ordinal scale. I want to use the x and y values and have the a third value display as a color in custom color scale.

I've been trying to extend the NRuleApplicator class and override the Apply method, put I can only go down to the NPointSeries type for NChartElement, which means that I can setup a single NFillStyle for the whole series. The NFillStile was extended to get the color scale color based on a index property to it.

How can I display the Z value in a 2D scatter chart as a color value in a colorscale? Should I extend NDataPoint?
