Kristian, I think you need to know how many plots you have on one page. You can access this by a=!p.multi[1] ;i.e. 3 in your example b=!p.multi[2] ;i.e. 7 in your example c=a*b ;21 factor=0.01 xyouts,7,3,'STRING',/data,charsize=.7-factor*c ;results in a ;smaller character depending on your number of plots on ;the screen You can now play with the factor for your needs. Alternatively you could use the system variable !p.clip. It contains the coordinates of the last plot on the device. In the example below you have for the first plot the numbers 30 and 290. This is a difference of 260 for the x-size of your last plot. This difference is constant for the following plots (e.g. 329 and 589). !P.CLIP The device coordinates of the clipping window, a 6-element vector of the form [(x0, y0, z0), (x1, y1, z1)], specifying two opposite corners of the volume to be displayed. In the case of two-dimensional displays, the Z coordinates can be omitted. Normally, the clipping window coordinates are implicitly set by PLOT, CONTOUR, SHADE_SURF, and SURFACE to correspond to the plot window. You may also manually set !P.CLIP if you want to specify a different rectangular clipping window or if the clipping coordinates have not yet been set in the current IDL session.
