Hi list,
Any chance to get a custom x axis log scale?
Hi Raphael:
Thanks for your interest in PLplot, and the answer to your question is
"yes".
The best way to figure out how to do anything with PLplot
is to consult the code for one of our standard examples.
For example:
# Search for case-insensitive "custom" in our C example source code.
software@merlin> grep -i custom examples/c/*.c
examples/c/x02c.c:// Use 100 custom colors in addition to base 16
examples/c/x02c.c:// Load default cmap0 colors into our custom set
examples/c/x19c.c:// A custom axis labeling function for longitudes
and latitudes.
examples/c/x19c.c: // Setup a custom latitude and longitude-based
scaling function.
examples/c/x19c.c: plscol0( 8, 100, 100, 100 ); //dark grey for
custom polygons - generally crags
examples/c/x33c.c: "Shade colorbars with custom labels",
So example 19 looks promising for your needs. Here is software for
that example for our various languages:
software@merlin> ls -l examples/*/*19*

Pick the language of interest to you, and go from there. Or if you
prefer
a GUI then consult <http://plplot.org/examples.php?demo=19>.
