I'm trying to display a task progress chart showing "complete", "late", and "not complete" in my dashboard and for some reason the chart will display as a column chart but it won't display as a donut chart even though I'm referencing the same report. I'd prefer to display as a donut chart as I think it looks better and is easier to read as it shows the task completion categories as a percentage of the whole.
Below are the two charts in the dashboard. The column chart displays fine, but when setting it up as a donut chart I get the error as shown in the chart on the right.
Below is the view of the chart while I am setting up the widget and it looks fine. After saving it displays the error noted above.
Below is the report that both charts are referencing.
