Graphs

The font sizes of graph labels are by default "scalable" to the size of the graph. To fix the size of the labels and thereby have them the same on all graphs regardless of graph size you can ...

* use an absolute font size in the label
* fix the size of all graphs to the same absolute size

To effect the former, double click on a label. That should bring up the label axis dialog box. Select the cursor before the graph label, then select the font size from the pull-down menu to the right. The "escape code" sequences for fixing the font size start with \Z ... \Z16 fixes the font size at 16pnt. An alternative to this is to select the first tap in the graph modification dialog box and set the default font size to be a certain value.

To effect the latter, double click on the outer "edge" (outside the graph axes) of a graph. This should bring up the dialog box to set the graph size as variable or absolute.

If you choose Graph->Modify Graph, you will see a Font Size setting. It is set by default to Auto, meaning that Igor automatically chooses a font size based on the graph size. This controls the size of axis labels, tick mark labels and annotations if you don't override it for individual elements. You can hardball this to the font size of your choice, 12 points for example. Then the font size will be independent of the graph size.

Once you have a graph with the formatting you want, you can use a style macro to apply that formatting to another graph. For details, execute:
