I am working in project in project that needs implement chart , I decide use MPAndroidChart its work just fine but I need some things done to be perfect to me

First can I change bars to specific image or it takes just images , as I have 3D image as bars in app design .

Second Can I put the legend to the right of chart in two line like image below and change legend text color

my java code 

mChart = (BarChart) view.findViewById(R.id.chart);
        mChart.setDescription("");
        Legend mLegend = mChart.getLegend();
        //mLegend.setPosition(Legend.LegendPosition.RIGHT_OF_CHART_CENTER);
FillBarChart(mChart);
}


private void FillBarChart(BarChart barChart) {
        ArrayList<BarEntry> entries = new ArrayList<>();
        entries.add(new BarEntry(87f, 0));
        entries.add(new BarEntry(90f, 1));


        ArrayList<String> labels = new ArrayList<>();
        labels.add("Omeprazole 20 mg");
        labels.add("Esomeprazole 40 mg");

        BarDataSet dataSet = new BarDataSet(entries, " ");
        dataSet.setBarSpacePercent(40f);
        BarData barData = new BarData(labels, dataSet);
        dataSet.setColors(new int[]{R.color.omeprazole_color , R.color.esomeprazole_color} , getActivity());
        barChart.setData(barData);
        barChart.animateY(3000 , Easing.EasingOption.EaseOutBack );
    }

You can do that if you create a custom Chart class and overwrite the init(). In this method, the Chart initializes a LegendRenderer and this is the point you need to get in and make changes.

Create a custom LegendRenderer and make sure that all the measurements are in place for those drawable. drawForm() method will allow you to draw the images instead of the default forms (Circle, Square, Line).
