possible bug in savechartasPNG

[robthewolf]

I have a TimeSeriesChart which I create:

Code: Select all

chart = ChartFactory.createTimeSeriesChart(
                this.getTitle(),       // chart title
                xLabel,                    // domain axis label
                yLabel,                   // range axis label
                dataset,                   // data
                true,                     // include legend
                true,                     // tooltips
                false                     // urls
        );

createChartPanel();

Elsewhere I have:

Code: Select all

public void saveChartToFile(File file) {
        chart.createChart();
        Logger.getLogger("bsdlog").warn("created chart");
        try {
            Logger.getLogger("bsdlog").warn("saving chart chart");
            ChartUtilities.saveChartAsJPEG(file, chart.getChartPanel().getChart(), 1440, 900);
            Logger.getLogger("bsdlog").warn("saved chart chart");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

This works fine!

however when I add:

Code: Select all

SegmentedTimeline timeline = SegmentedTimeline.newMondayThroughFridayTimeline();
((DateAxis) chart.getXYPlot().getDomainAxis()).setTimeline(timeline);

it gets stuck at the line:

Code: Select all

ChartUtilities.saveChartAsJPEG(file, chart.getChartPanel().getChart(), 1440, 900);

no crash, no error message no nothing.

Any ideas as to why this is happening? And what I can do to work around it.

Did you ever figure this out?
I am having the same problem.
Seemed to happen when I switched to java 1.8
