Chart font size

[achengscode]

Is there anyway to set the font size that's used when the chart is being drawn?

It's frequently changing when I try it on different devices (some devices, it appears extremely small, on others it's extremely large).

Thanks

Which fonts are you talking about?
x-axis labels? y-axis labels? legend? values inside the chart?

I'm talking about the values inside the chart (the y-values).

Thank you for informing me, actually there is no possibility to directly set the font size :)

I will implement this right now and this feature will be included in the next update.
In the meantime, you can use a workaround like this:

Paint p = mChart.getPaint(Chart.PAINT_VALUES);
p.setTextSize(...);

mChart.setPaint(p, Chart.PAINT_VALUES);

EDIT: Unfortunately, the getPaint(...) feature is still buggy.

Another solution:

Copy this code snippet into the Chart.java file of the library and use it:

    /**
     * Sets the font size of the values that are drawn inside the chart.
     * 
     * @param size
     */
    public void setValueTextSize(float size) {
        mValuePaint.setTextSize(Utils.convertDpToPixel(size));
    }

Then call mChart.setValueTextSize(...) whenever you need it.

Also, the latest commit on the experimental branch already supports everything you need.
