Describe the issue:

I want to display a custom HoverCard in my LineChart, so I pass in a customHoverChart using onRenderCalloutPerDataPoint that takes props of ICustomizedCalloutData type. My ILineChartPoints have values for xAxisCalloutData and yAxisCalloutData. However, when I try to access these values like {props.values[0]?.xAxisCalloutData} and {props.values[0]?.yAxisCalloutData}, I cannot only access the xAxisCalloutData value. I can only access the yAxisCalloutData value.

Actual behavior:

I can't access the xAxisCalloutData.

Expected behavior:

Being able to access the xAxisCalloutData value.

If applicable, please provide a codepen repro:

In the HoverCard, "xtext2" should also appear.
