2 Questions about the MPAndroidChart library.
All my yvalues are integers, but displayed as Decimals.
How can I get them displayed as integers (without the digits)?
How can I prevent that the ylabels are also shows as decimals?
I know there is a setFormatter for the yvalues, just don't understand how to use...
Have a look at the
ValueFormatter interface provided by the library.
With that interface, you can custom format all values that are displayed in the chart (also y-labels). Simply create your own class that implements the interface and return whatever you want to be displayed.
chart.setValueFormatter(new YourValueFormatter()); YLabels yl = chart.getYLabels(); yl.setFormatter(new YourValueFormatter());
UPDATE (for versions 2.0.0+ of this library):
ValueFormatter can be set for each
DataSet separately, or the same
ValueFormatter can be set for the whole data object containig all
DataSets. Furthermore, the
YLabels class is now called
// set for whole data object (individual DataSets also possible) LineData data = new LineData(...); data.setValueFormatter(new YourValueFormatter()); // YLabels are now called YAxis YAxis yAxis = mChart.getAxisLeft(); // get the left or right axis yAxis.setValueFormatter(new YourAxisValueFormatter());
UPDATE (for versions 3.0.0+ of this library):
The interfaces for formatting have been renamed and extended in their functionality. Now, the
IAxisValueFormatter can be used to format values of both
