# Edit mode

Using Editps to edit single .eps files

This option is mainly used to translate, re-size or rotate .eps graphs, e.g. to enlarge graphs in portrait orientation in order to print them in landscape orientation.

First you read in any .eps file. Then you can move the margins, translate the graph, re-scale or rotate to any angle. However, note that, if you scale the axes differentially and rotate, then these operations do not commute. To understand this feature, scale the x axis by 0.5 and the y axis by .75 then rotate by 45 degrees, say. Now note the effect of changing the order of rotation and scaling by changing the shearing status. Shearing a differentially scaled graph can be used to create interesting three dimensional effects.

To add a new title or extra text under an edited file, use Editps in stack mode (with 1 file). To add a large or multi-line title or text to the top of a file, use Editps in Create mode to make the desired text, then use Editps in Overlay mode to overlay the text as required.

Note that, if you intend to add titles and text in this way, you should suppress the title in the original plot when using program Simplot.

Extra possibilities with SIMFIT files

Editps will edit any .eps file but, since SIMFIT files use a unique formatting convention, you can also edit graphics titles and text, etc. with SIMFIT .eps files. This is mostly used to correct a title for spelling mistakes or to add special features like maths symbols or degree centigrade symbols, etc.
