Changing the font size of point labels in a Contour Plot

DMR — Thu, 28 Jul 2016 18:49:13 GMT

Hi,

In a Contour Plot (or for that matter any chart in which points are automatically labelled with the contents of one or more specified rows and/or columns in the data set from which it is generated) is there any way to change the font size of the labels?

I know I could increase them manually with a Control-Shift-Plus key combination, but doing that increases the font size in every open window, whereas I want the change limited to just the window containing the chart in question. The same objection precludes my simply modifying the default font size in the Preferences.

Alternatively, I could simply turn them off and replace them with a set of annotations of my own in a larger font size, but if I do that I lose the ability to drag them about the chart manually afterwards - and I'd like to retain that functionality if possible.

Is there any other way to do it?

Many thanks

You can change the defaults in the Preferences

Hi Jim, doing that will affect every chart in my output; unfortunately I need to restrict the change to just the one chart I'm working on. Am I right in thinking this isn't possible?

Kind regards,

David

You are correct in your assumption. The only work around that I can think of, is to turn off the labeling and to write a script that places the labels on the chart. This can be done with a "Make Row State Handler" and "Add Graphics" messages to the chart. Using this method, you can make the font any size you want.

Hi Jim - I suspected as much, but it's always good to know I'm not missing a trick. Many thanks.
