Text-Labels on Pie Charts about hellocharts-android

Hi, Im not sure if I understand what you mean by text labels.

For text labels instead of numeric values use method sliceValue.setLabel(char[]), dirty example:

SliceValue sliceValue = new SliceValue(44, Color.RED);
sliceValue.setLabel(("Students " + (int)sliceValue.getValue() + "%" ).toCharArray());
//or just
//sliceValue.setLabel(("Students 44%" ).toCharArray());

This will give you something like this:

If by text labels you mean chart's legend - unfortunately it is not supported yet and for now you you will need to add some TextViews beside ChartView.

Thanks. This is awesome. Exactly what I wanted.

Now I also have a column chart. Is it also possible to make labels at the bottom of the columns?
This is what I have, but adding setLabel on column seems not to work:

values = new ArrayList();
values.add(new SubcolumnValue(273, Color.parseColor("#FF4444")));
column = new Column(values);
columns.add(column);

any ideas?

In case of column chart you need to set label on SubcolumnValue objects.

columns = new ArrayList<Column>();
for (int i = 0; i < numColumns; ++i) {
    subcolumns = new ArrayList<SubcolumnValue>();
    for (int j = 0; j < numSubcolumns; ++j) {
        SubcolumnValue subcolumn = new SubcolumnValue((float)Math.random(), Color.RED);
        subcolumn.setLabel("some_label".toCharArray());
        values.add(subcolumn);
    }

    Column column = new Column(subcolumns);
    column.setHasLabels(true);
    columns.add(column);
}

Labels are displayed above bar for positive values and below for negative, no option to display all labels at the bottom.

Is it possible to change labels background and/or labels text color?
