Microsoft's Gantt Chart, Maximum Tasks Count

Good day,

I am using Microsoft's Gantt Chart (2.2.3) to produce a visual comparison between hours on shift for two different datasets. One of which has durations spanning hours, with tens of thousands of rows, and the other with durations spanning seconds with hundreds of thousands.

The group task functionality is being used.

Because of the high number of rows in use, the Gantt chart's max number of "tasks" have been reached, limiting the information being shown.

Adjustments can be made (using Power Query Editor) to reduce the number of data points being used, but I would like to know: what is the maximum number of tasks this Gantt Chart is capable of producing? Using this information, I can reduce the number of rows considered till this point is reached.

Thank you
