How to set colors in MPAndroidChart?

Question

I use MPChartlib for the base "Barchart" (3 bars and values ​​from 0 to 100).

the background of the application is dark, so I want to put the text in white, but when I set the text with the color code "FFFFFF" to chart_color stored in the string.xml file, but the text is displayed in 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 a lot of things and research, but could not find the problem, is not lib using the same color code or something else?

Thanks for your help, Alex

Answer 1

You pass the resource identifier to the library, not the actual color .

Use this to get the color:

  int color = getResources().getColor(R.color.chart_color); something.setColor(color); 

You can also find this in the documentation.

Answer 2

if you want the color of the partitions to prefer to convey the context in the same way as the example below

 ArrayList<BarEntry> entries = new ArrayList<>(); entries.add(new BarEntry(87f, 0)); entries.add(new BarEntry(90f, 1)); ArrayList<String> labels = new ArrayList<>(); labels.add("title 1"); labels.add("title 2); BarDataSet dataSet = new BarDataSet(entries, "# of Calls "); BarData barData = new BarData(labels, dataSet); dataSet.setColors(new int[]{R.color.color1 , R.color.color2} , context); barChart.setData(barData); barChart.animateY(3000 , Easing.EasingOption.EaseOutBack );
