Fonts seem smaller than they should in charts

[eladmena]

Hey.
I'm having a problem with font sizes in the title or axes.
setting a font for the title or axes makes the font look smaller by about 1.5 than the specified size.
As a workaround I have set the font getter to return a font with the original size multiplied by 1.5, but that's not the ideal solution
setting a larger chart area doesn't affect the size of the font.

Is this a known issue?

Thanks
Elad

Code: Select all

chart.getTitle().setFont(<someFont>)

If the size of the ChartPanel exceeds the dimension defined by maximumDrawWidth and maximumDrawHeight, it will still render the chart in a Rectangle with maximumDrawWidth and maximumDrawHeight but then scale the chart to fill the entire size.
Does it look better if you call chartPanel.setMaximumDrawHeight(10000) and chartPanel.setMaximumDrawHeight(10000)?

I'm not using ChartPanel.
I only use it to create images using: chart.createBufferedImage(<Width>, <Height>);

JFreeChart uses ordinary Java2D calls to draw strings. Do the fonts of JButton and JLabels look equally wrong?

Sorry for the late reply, I wasn't at work for a while.
Testing JLabel produced the same size of fonts as the generated charts.

Thanks

If JLabels and JButtons are not displayed as expected as well, then either your expectations are too high or your JVM has a bug.
What is your OS and JDK version ?

Perhaps the browser you are using to display the generated images is scaling the image?
