The preview showed the rotated x-axis text just fine, it was only on the live site that it disappeared. So I assume it wasn’t a matter of lack of room.
Thank you for the assistance. I found that the x-axis text would not display when it was angled, the default behavior. I’ve decided that with my theme apparently being so much at odds with your package I’ll probably look for other solutions.
Thanks. On the advice of my programmer, instead of adding additional CSS into the theme, which he thought was a bit problematic, he had me insert HTML directly in the post with a style statement setting font size to 16. This worked pretty well, but the text below the x-axis is not there. Is there something more we need to do?
