Bar chart sourced from a report definition is showing undefined instead of 0 for aggregated column

I have created a report to count the case IDs based on case status .

When there are zero values for the aggregate column pyID in the bar chart, the value is being shown as ‘undefined’ instead of 0 when the mouse is hovered over the bar.

How can we display 0 instead of ‘undefined’?
