I know this is very old, but for the next user, it may help to have the solution.
You can specify the date format to use
/**
* Creates a time chart intent that can be used to start the graphical view
* activity.
*
* @param context the context
* @param dataset the multiple series dataset (cannot be null)
* @param renderer the multiple series renderer (cannot be null)
* @param format the date format pattern to be used for displaying the X axis
* date labels. If null, a default appropriate format will be used.
* @return a time chart intent
* @throws IllegalArgumentException if dataset is null or renderer is null or
* if the dataset and the renderer don't include the same number of
* series
*/
public static final Intent getTimeChartIntent(Context context, XYMultipleSeriesDataset dataset,
XYMultipleSeriesRenderer renderer, String format) {
return getTimeChartIntent(context, dataset, renderer, format, "");
}
To show only day and month, use something like the following:
Intent intent = ChartFactory.getTimeChartIntent(context, dataset, mRenderer, "dd-MMM");
