Start with a range with "Starter" and "Professional" in the first column and two zeros in the second. Insert a bar chart. This provides labels, but the zero means the bars do not show.

In another two columns, place 1 for Starter and 2 for Professional in the first column, and the Y values in the second. Copy this range, select chart, use Paste Special (categories in first column).

Right click on this new series, choose Change Chart Type, select XY Scatter. Again right click on new series, choose Format Data Series, select Primary Axis where given a choice.
