Automatic generate line color visible on white background

[yccheok]

Currently, I have a chart which is using white color as background. Most of the time, the drawn line series with auto color, may yield certain line colors, which its color is hardly visible on white background.

I try to manual specific the color.

Code: Select all

    public static void setPriceSeriesPaint(XYItemRenderer xyItemRenderer) {
        xyItemRenderer.setSeriesPaint(0, new Color(255, 88, 88));
        xyItemRenderer.setSeriesPaint(1, new Color(0, 255, 0));
        xyItemRenderer.setSeriesPaint(2, new Color(0, 0, 255));
        xyItemRenderer.setSeriesPaint(3, new Color(255, 0, 0));
    }

However, there is no limits on the line series which can be drawn. Hence, after specific several colors manually, I find it is rather difficult to provide a reasonable large set (says 50) of color which is visible on white background, by doing it manually.

Is there any automated way, which I can use. Instead of choosing the color manually?
