[Matplotlib-users] Many basic questions i cant find solution
Hello, i am not a user of matplotlib, i just have to do something in it. I managed to get the plot i wanted, but i have been going around for hours trying to do some fine tuning and cant get around it. The matplotlib seems way too extense for me to find the solutions without studying it avidly, and i just dont have the time... But trust me, i've looked everywhere and tried everything... What i need to do is: - Change the axes labeling (if its like 1 2 3 4 5 6 change it to A B C D for example) - Resize the window, not the plot (I have the figsize=(6,10) and thats fine for the plot, but the colorbar just gets cut in half, cant fit in the window) Thankyou in advance -- View this message in context: http://old.nabble.com/Many-basic-questions-i-cant-find-solution-tp31088840p31088840.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

[Matplotlib-users] Changing labels to time
Hello all, i have certain dates that i want to use as the xlabels, i have looked around but found nothing i can use. I get the date from the netcdf file in a format something like a timestamp, like: 16216 that i turn into 04:30:16 I want to know how can i use this as a label.

[Matplotlib-users] Computer freezes plotting
Hello all, i have made a python script to plot some netcdf files that go from 4mb to 80mb, and the main purpose is to plot one after another. This seems to work fine, no problems there, but sometimes the computer crashes and i belive its beacause the files are too big. Is there any way to accelerate the plot time or reduce memory consumption? If your asking whats the error, well, actually i get no error, it just never finishes plotting. I tried to wait for like 10 hours, and nothing happened so i assume it crashed.

[Matplotlib-users] Re size the colorbar
Ive seen lots of examples around, but i cant seem to adapt any to my
implementation.
The only thing i want is to change what values the colorbar shows. In the
colorbar there are values from 1 to 1e+9, and im only interested in the
values from 1e+4 to 1e+9...
pc = ax.pcolor(pr[2].transpose(),norm=LogNorm(vmin=1),cmap=cm.jet)
ax.set_yticks(np.arange(0-(arr_agl[0]*escala)/1000,
(arr_agl[600]*escala)/1000, escala))
ax.set_yticklabels(range(20))
ax.set_ylim(0, 600)
ax.set_xlim(0,len(valores2))
ax.xaxis.LABELPAD = 18
for label in ax.get_xticklabels() + ax.get_yticklabels():
label.set_fontsize(16)
plt.xlabel('Time of Measurement',fontsize=16)
plt.ylabel('HEIGHT above ground level, km',fontsize=16)
colorbar = fig.colorbar(pc)
Thx...
