## Annotated template

A
  The two datasets shown in red and black will be generated from file#1 using rule tiso and tani, respectively (as indicated by `$'1:tiso` and `$'1:tani`). The legend entry will be depending on what the application sets for `$rule` in each of the datasets (this will be `tiso` and `tani`). Note that the datasets of all other graphs have similar legend strings, with varying filenumbers.

B
  The data files contain certain auxiliary information concerning the conducted experiment. The application provides this information in form of variables. The text object shown here can access a variable named `probe` that was set for the graph g0 (with the light red background color) by stating "`${g0::probe}`". In case the variable could not be set, the fallback string "`N/A`" will be printed instead.

C
  Here, the same variable as in annotation B is accessed. However, since it is referred to from within the subtitle of set g0, we can simply use "`${probe}`" instead of "`${g0::probe}`". Both ways are valid, here.

D
  Here you can see a variable reference without a fallback string. If for any reason, `zero` in graph g2 cannot be resolved, the result will be no change to the string at all, i.e. the generated file will show "`zero=${g2::zero}`" to help you find the problem.

E
  By default, GraceTMPL autoscales the axes according to the data provided by the application. This behavior can be suppressed by the template for certain axes. Prepending and Suffixing the axis title with two spaces is sufficient (that's why you can't really see it here...).
