I'm using MPChartlib for a basic "Barchart" (3 bars and values between 0 and 100).
the background of the app is dark so I'd like to put the text in white but when I set the text with color code "FFFFFF" in chart_color stored in string.xml but the text appear in dark blue.
//Axe X
XAxis x = barchart.getXAxis();
x.setPosition(XAxisPosition.BOTTOM);
x.setTextColor(R.color.chart_color);
x.setAxisLineColor(R.color.chart_color);
// Design
barchart.setDragEnabled(false);
barchart.setDrawGridBackground(false);
barchart.setTouchEnabled(false);
barchart.setHighlightEnabled(false);
barchart.setMaxVisibleValueCount(101);
barchart.setDescription(null);
barchart.setGridBackgroundColor(R.color.chart_color);
barchart.invalidate(); // refresh
//Axe Y
barchart.getAxisLeft().setAxisMaxValue(100);
barchart.getAxisLeft().setDrawTopYLabelEntry(true);
barchart.getAxisLeft().setDrawAxisLine(false);
barchart.getAxisLeft().setDrawGridLines(false);
barchart.getAxisLeft().setAxisLineColor(R.color.chart_color);
barchart.getAxisLeft().setTextColor(R.color.chart_color);
barchart.getAxisRight().setAxisMaxValue(100);
barchart.getAxisRight().setDrawTopYLabelEntry(true);
barchart.getAxisRight().setAxisLineColor(R.color.chart_color);
barchart.getAxisRight().setTextColor(R.color.chart_color);
I tried lots of things and research but couldn't find the issue, does the lib doesn't use the same kind of color code or something ?
Thanks for your help, Alex
You are passing the resource id to the library, not the actual color.
Use this to get the color:
int color = ContextCompat.getColor(context, R.color.chart_color);
LineDataSet dataSet = ...;
dataSet.setColor(color);
You can also find this in the documentation.
