Sets the Grace plot in multiplot mode and plots in location given by index (there are cols by rows subwindows).
Input:
- rows
- Number of rows in subplot grid.
- columns
- Number of columns in subplot grid.
- index
- Index of subplot where to make the next plot.
If only one argument is supplied, then it must be a three digit value specifying the location in digits 1 (rows) and 2 (columns) and the plot index in digit 3.
The plot index runs row-wise. First all the columns in a row are filled and then the next row is filled.
For example, a plot with 4 by 2 grid will have plot indices running as follows:
+——+——+——+——+ | 1 | 2 | 3 | 4 | +——+——+——+——+ | 5 | 6 | 7 | 8 | +——+——+——+——+
