plotutils

[Mark P. Esplin]

        The command line program "graph" from plotutils-2.4.1 gives useless 
results 
if the number of points to plot is greater than 1024 points.  The plot is 
total garbage and the error messages aren't of value.  The messages are: 

libplot: not drawing a text string that is positioned too far for X11
libplot: not drawing a text string that is positioned too far for X11
...
libplot: not drawing a text string that is positioned too far for X11
libplot: truncating a polyline that extends too far for X11

        I installed from source on a RedHat 7.3 system from the 
plotutils-2.4.1.tar.gz download.  I recently upgraded from SuSE 7.1.  The 
plotutils rpm that came with the SuSE system must have had a different 
maximum number of points since I never had this problem before.  

        I changed line 228 of graph.c to a larger number and recompiled it and 
was 
able to graph my data.  Having the source is wonderful!  

        In my work, it is very useful to be able to graph large data sets even 
if the 
detail of the plot are not resolved on the screen.  It is still possible to 
see over all patterns in the data.
