Okay, I am another gnuplot user trying to migrate over to matplotlib.
I like what I see, but there are a couple things that are very easy to
do in Gnuplot that I can't figure out how to do with matplotlib.
I have a file with 3 columns of data called data.txt that looks like:
0.0000 1.0000 1.0
0.0634 1.0655 1.1353
0.1269 1.1353 1.28899916094
0.1903 1.2097 1.46345358199
0.2538 1.2889 1.6615188369
0.3173 1.3734 1.88639043926
...
I can plot this data, 2 versus 1 and 3 versus 1, very easily on the
same plot, with a legend, with log y values, and only for the xrange
between 2 and 3 with gnuplot:
set log y
set xrange[2:3]
plot 'data.txt' u 1:2 w l t 'apples', 'data.txt' u 1:3 w l t 'oranges'
Now, how do I do that same thing with matplotlob? Ie:
1. Both graphs overlayed on the same plot.
2. Semilogy. (log y values),
3. Only ploy for x in the range 2-3.
4. Legend for the two graphs on same plot.
I have spent time looking through the documentation but I can't find
anyway to do this is any straightforward way. plotfile() looks
promising, but I can't seem to make it do the above. Thanks in
advance.
