The previous code already loops over all categories to check if they are present, typically nested in a loop adding many data items, thus already scaling quadratically when adding lots of mostly unique data points.

Found another problem.  It looks like it is present in the master branch, so this is a separate issue.  To reproduce with the Monkey Tester:

- select bar chart page
- right click, select "Add Series with Duplicate Category" twice
- click "Add Series" button on the right, under XY Chart
- resize the chart using the split pane on the right (or vertically)
The series added via context menu are not getting resized
