not center

To be honest, I don't see the value of the LayeredBarRenderer at all (relative to a "plain" bar chart), but comments from others are welcome.

It might be mere eye candy, but I like the look of the not centered LayeredBarRenderer.

[david.gilbert]

I agree that the modified version looks better, for sure.

this really layerchart

but I modify your LayeredBarRenderer.java,add a flag center control is or not center.

Code: Select all

public LayeredBarRenderer(boolean center) {
        super();
        this.center=center;
        this.seriesBarWidthList = new ObjectList();
    }

and modify your funtion drawVerticalItem

Code: Select all

        if(center)
        {
          bar = new Rectangle2D.Double(
              (rectX + ( (seriesCount - 1 - row) * shift)), rectY,
              (rectWidth - (seriesCount - 1 - row) * shift * 2), rectHeight);
        }else
        {
          bar = new Rectangle2D.Double(
              (rectX - ( (seriesCount - 1 - row) * shift)), rectY,
              (rectWidth - (seriesCount - 1 - row) * shift), rectHeight);
        }
