dynamic marker not visible on bar chart

[ashish-lava]

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

i am trying to make custom markers where i am using markerview and adding my custom dynamic views, but when i am clicking the bars it is highlighting but not showing my any markers at the top. nothing is visible. I have debugged it is going in refreshContent delegate but it is not showing any view.

What did you expect to happen?

i want my custom marker to be visible on click of bars

What happened instead?

bars are highlighted but it is not showing any markers
