OverlaidVerticalCategoryPlot Color

[Luke Hillary]

Hi, I've got some code similar to the following:


DefaultCategoryDataset dataset = new DefaultCategoryDataset(data);
dataset.setSeriesNames(chartSeriesNames);
dataset.setCategories(ChartXAxisLabels);

HorizontalCategoryAxis xAxisObject = new HorizontalCategoryAxis(xAxis);
VerticalNumberAxis yAxisObject = new VerticalNumberAxis(yAxis);

OverlaidVerticalCategoryPlot plot = new OverlaidVerticalCategoryPlot(xAxisObject, yAxisObject, ChartXAxisLabels);

VerticalBarRenderer barRenderer = null;
barRenderer = new VerticalBarRenderer();
VerticalCategoryPlot bars = null;
bars = new VerticalCategoryPlot(dataset, null, null, barRenderer);

LineAndShapeRenderer dotRenderer = null;
dotRenderer = new LineAndShapeRenderer(LineAndShapeRenderer.LINES);
VerticalCategoryPlot dots = null;
dots = new VerticalCategoryPlot(dataset, null, null, dotRenderer);

plot.add(bars);
plot.add(dots);

JFreeChart chart = new JFreeChart(xAxis + " vs " + yAxis + " for " + theProduct, JFreeChart.DEFAULT_TITLE_FONT, plot, true);


For some reason the background color of the plot is light grey (not the default white), so basically the whole chart is grey. How can I change the color of the plot, I've tried doing :

chart.getPlot().setBackgroundPaint(Color.white);

But it has no effect. I can change the color of the whole chart by doing:

chart.setBackgroundPaint(Color.white);

But this changes the background color of the axis as well, which I don't want to do.

Thanks.

p.s I know I'm using the same dataset for the bar and line plots, it's just for testing.

Hi Luke,

There's a bug in the OverlaidVerticalCategoryPlot class - I had one look at fixing it a while back, but it wasn't a straightforward fix (as far as I could tell) and I had only limited time so I had to give up on it. I hope to get back to it some time...
