I am displaying 4 values in a bargraph where each bar is different color. when I am displaying the graph each bar overlapping each other. I want to make space between the bars I tried with setBarSpacing()
by putting different values still its not working. is there any other idea.
package com.example.barchartview;

BarChartView = ChartFactory.getBarChartView(this, getBarDataset(), renderer, Type.DEFAULT);
LinearLayout playout = (LinearLayout) findViewById(R.id.graph2);
playout.addView(BarChartView);

}
else
{
BarChartView.repaint();
BarChartView.setVisibility(View.GONE);
}
}

here is my code.
here is my activity_main.xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
I changed all your series to XYSeries
and add them simply to the dataset
, without calling extra methods.
XYSeries series1 = new XYSeries("A");
dataset.addSeries(series1);
Then, add data like in a regular XYChart like this:
series1.add(1, value);
series2.add(2, value);
