MPAndroidChart, set different color to bar in a bar chart based on y axis values

Question

I'm plotting a bar chart using MPAndroid chart. Now all my bars have the same color but I want different colors for the bars based on Y axis values, like if value >100. color = red, like in the picture below. Is that possible? someone please help me.

Regards.

Answer 1

You can override the BarDataSet class to achieve this

public class MyBarDataSet extends BarDataSet {       public MyBarDataSet(List<BarEntry> yVals, String label) {         super(yVals, label);     }      @Override     public int getColor(int index) {         if(getEntryForXIndex(index).getVal() < 95) // less than 95 green             return mColors.get(0);         else if(getEntryForXIndex(index).getVal() < 100) // less than 100 orange             return mColors.get(1);         else // greater or equal than 100 red             return mColors.get(2);     }  } 

And you need to define your colors like this:

MyBarDataSet set = new MyBarDataSet(yVals, ""); set.setColors(new int[]{ContextCompat.getColor(context, R.color.green),                  ContextCompat.getColor(context, R.color.orange),                  ContextCompat.getColor(context, R.color.red)}); ArrayList<BarDataSet> dataSets = new ArrayList<>(); dataSets.add(set);   BarData data = new BarData(xVals, dataSets);

You can find out the documentation about setting colors in MPAndroidChart from this link

    LineDataSet setComp1 = new LineDataSet(valsComp1, "Company 1");   // sets colors for the dataset, resolution of the resource name to a "real" color is done internally   setComp1.setColors(new int[] { R.color.red1, R.color.red2, R.color.red3, R.color.red4 }, Context);    LineDataSet setComp2 = new LineDataSet(valsComp2, "Company 2");   setComp2.setColors(new int[] { R.color.green1, R.color.green2, R.color.green3, R.color.green4 }, Context);
