Below are charts with the labels horizontal and vertical. The vertical ones fit better, but are arguably no easier to read. The best you can do is pick short mnemonic labels. <p align="center"><img src="http://peltiertech.com/WordPress/wp-content/img2/TwoRowCatLabelsHoriz.png" alt="Horizontal Inner Category Labels" /><img src="http://peltiertech.com/WordPress/wp-content/img2/TwoRowCatLabelsVert.png" alt="Vertical Inner Category Labels" /></p> You can change the orientation of the category labels, but only the set of labels closest to the axis are affected.

If this is done in a general sense, longer words get truncated/overlapped easily... When you use two columns as the category axis, is there a way to change the formatting on that second row?

The +/-, high/low designations are arbitrary. You could consider them to be like True/False, or like any choice among categorical factors. Red/Green, Left/Right, Male/Female, Jack/Jill. What matters isn't the order in which you list the factors, but the slope of the line connecting the two values. Actually, the factors need not be numerical.

Low pH would corrode faster, high temperature would corrode faster, and low chrome would corrode faster. That's one positive and two negative effects.

It's very clean and easy to understand. This is probably out of scope with the post, what kind of data would allow a higher negative value than a positive value (example X1)? I would like to adapt this chart to some of the analysis that I do. Thanks again. John Mansfield Jon,
