John,
This is not an issue with your table, it is an idiosyncracy of GraphBuilder with Overlay:
- Boxplots are offset, but
- Points are not offset.
[The message you pointed to the user had two Y values]. I have a couple alternatives and recommendations:
- Keep your graph as is. Now drag Type to just above your X axis of Percent Type 1/2. Then points and boxplots are a little offset. But this is more readable.
- Using the graph above, remove Type from overlay. Now the points an boxplots are aligned. However, unfortunately, the boxplots are all one color, that takes a little scripting (or point an clicking) to change (see below).
- If it is difficult to drag Type to just above the X axis of Percent Type 1/2, create a new column called Percent Tpe that is the combination of columns Percent Type1/2 and Type (highlight those two columns, then from the main menu select Cols>Utilities>Combine Columns, and use this for the X axis.
I have a recommendation to right click on the column you use for teh X-axis and select Property Value Ordering, so you can get the order you prefer on the X-axis.
To customize the color of the boxplots, Right click in on the graph (framebox) and select Customize. You will see each boxplot listed. Click on sech one and select the coordinating color for Type. If you are doing ths often, this can be done with a script, vs. point and click.
Hope that helps. This should be marked as a wishlist item to have a Graph Builder option to offset points when Overlay is used, so the offset matches the boxplot offest.
