coloring bar chart

[Anonymous]

hi,
i would like to put a specific color on one and only one bar of my bar chart which contains only one serie.  is it possible? i have found a lot of examples allowing to color a complete serie but this is not what i am trying to do.

thanks a lot

You will have to extend the BarRenderer and use that class to modify the color of the bars.

How do you change the BarRenderrer?

public class ExtendedStackedXYBarRenderer extends StackedXYBarRenderer
{
  /** Farben fr die Items */
  private Paint[][]         paintArray           = null;

  /** Sollen die Farben der einzelnen Items genutzt werden? */
  private boolean           isPaintArray         = false;

  public void setItemPaint(Paint paint, int row, int column)
  {
    this.paintArray[row][column] = paint;
  }

  public Paint getItemPaint(int row, int column)
  {
    Paint returnPaint = null;

    if (this.isPaintArray)
    {
      returnPaint = this.paintArray[row][column];
    }
    else
    {
      returnPaint = super.getItemPaint(row, column);
    }
    return returnPaint;
  }

}
