MarkerView in MPAndroidChart

Can we add MarkerView to PieChart and HorizontalBarChart from MPAndroidChart library?

I did try adding the MarkerView to the pie chart as the following:

TooltipView tooltipView = new TooltipView(context,R.layout.tooltip_layout, metadata);
chart.setMarkerView(tooltipView);

But when I click on the slice of the pie chart, no MarkerView is shown. Also, the same thing happens for horizontal bar chart.

I have the same issue with HorizontalBarChart. I'm using v2.1.3 of MPAndroidChart library. My implementation of custom MarkerView is correct, because if I simply change HorizontalBarChart to BarChart everything works as expected. Once I return HorizontalBarChart back, no markers are displayed. - HitOdessit

As of today, PieChart and HorizontalBarChart do not support MarkerView. Nevertheless, this is high on my list and will probably be added soon in the future.

It's difficult to tell from your question, but here are some things to check:

  • Ensure that ToolTipView extends MarkerView
  • Also make sure that you implement the refreshContent(), getXOffSet() and getYOffSet() methods.

That should allow you to view the marker view item.

I am not sure what the metadata value you are entering does, as the refresh method should allow you access the currently selected value and its data.
