How to show multiple icons above same bar in barChartView

Plotted bar chart with sample data and showed icon on a specific point.

When I plotted two icons on the same point icon got overlapped as shown in the picture below

But I want icons to be stacked one by one on top of the bar.
example:

Start at the barChartView icon-rendering entry point and reproduce the reported case with two icons at the same data point. Determine how overlapping icons are positioned, then verify that multiple icons appear stacked above the bar without disturbing other chart elements.
