What order to set data/series/label design

[Richard]

I have the following code

 

BarSeries weekBarSeries = new BarSeries();
weekBarSeries.setCategoryBinding(new PropertyNameDataPointBinding("DayOfWeek"));
weekBarSeries.setValueBinding(new PropertyNameDataPointBinding("EnrollmentCount"));
weekBarSeries.setDataPointRenderer(new CustomBarChartRenderer(weekBarSeries, WEEK_SERIES_COLORS));
weekBarSeries.setData(oneWeek);

weekBarSeries.setShowLabels(true);
weekBarSeries.setLabelFillColor(Color.TRANSPARENT);
weekBarSeries.setLabelStrokeColor(Color.TRANSPARENT);
weekBarSeries.setLabelTextColor(0xff84cc28);

weekChartView.getSeries().add(weekBarSeries);

CategoricalAxis weekHorizontalAxis = new CategoricalAxis();
weekChartView.setHorizontalAxis(weekHorizontalAxis);

LinearAxis weekVerticalAxis = new LinearAxis();
weekVerticalAxis.setLabelFormat("%2.0f");

weekChartView.setVerticalAxis(weekVerticalAxis);

upTitle.setText(DESApplication.getInstance().getCustomString("screen_02_chart1_title"));

upper.addView(weekChartView);

However, the style of the labels remains the same as the default style - light blue boxes with white text.

Does the custom data point renderer have to implement anything to handle the custom label attributes?

The code for that renderer is code you gave me to implement a multi colored bar chart.

Removing the call to the custom data point renderer made no difference. It appears this code has no effect

 

weekBarSeries.setShowLabels(true);
weekBarSeries.setLabelFillColor(Color.TRANSPARENT);
weekBarSeries.setLabelStrokeColor(Color.TRANSPARENT);
weekBarSeries.setLabelTextColor(0xff84cc28);

Hi Richard,

By default the chart gets its colors from the chart palettes. This means that any inline settings will be overwritten by the palettes. You have to either edit the current palette itself, or disable the palettes and then make your inline settings. You can read about the chart palettes here.

To disable the palette on your series call weekBarSeries.setCanApplyPalette(false). Then setLabelColor() and setFillColor() should work. Please note that after you disable the palette you will also have to provide the other visual settings like label size etc. because the palette will not set them.

Another thing I forgot to mention. The key for the series labels is "SeriesLabels". To get the entries for the series labels you have to call 

palette.entriesForFamily("SeriesLabels");
