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
IValueFormatter interface provided by the library. With that interface, you can completely customize what gets displayed on the chart based on your own logic.
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
IValueFormatter interface is used to customize chart values.
Link to the ValueFormatter documentation.
If all you want is to change the number of decimal places on the values, the
DefaultValueFormatter will suffice.
pieDataSet.setDefaultValueFormatter(new DefaultValueFormatter(digits = 1)) //where digits is the number of decimal places
The example above will format 88.65 as 88.7
