XYPlot blurry ...

[Nick_000]

Hello, I am using JFreeChart to generate mass spectrum, there are only vertical lines, and hundreds lines in one plot, however I found that some lines are blurry, I was trying to use plot.setShadowGenerator(null), but it didn't work, and I also tried

Code: Select all

XYLineAndShapeRenderer renderer = (XYLineAndShapeRenderer) plot.getRenderer();
        for (int i=0; i<seriesCount; i++){
            renderer.setBaseShapesVisible(false);
            renderer.setBaseShapesFilled(true);
            renderer.setSeriesStroke(i, new BasicStroke(1));
            
        }

still didn't work... I was wondering if there was any way to make each line 1px without blurry edge, thank you!

If you're rendering with ChartUtilities, consider what image type to use.

I did't use ChartUtilities to render and generate a pic, I just display the plot on a panel, but the some lines are blurry, and some line is only a single line...

Override getPreferredSize on the panel and return a suitable size.
