Hello,
Apologies for a basic question, but I am struggling with simply making a seismogram background transparent. I have written:
guio.plot(color=‘red’, starttime=start, endtime=end, transparent=‘True’, number_of_ticks=8)
but when I save the file as a .png and try to import into Illustrator, for example, the plot is not transparent, but rather white. I am hoping to extract waveforms with a transparent background but with a red trace to the waveform.
Thank you for the help,
Greg
Hi Greg,
you might have to save directly to a file to get the transparency. It is not super straightforward to achieve transparency in matplotlib. Also you used a string that says 'True' instead of the boolean value True so this might also be the problem.
Anyways, the following creates a transparent png on my PC:
>>> guio.plot(outfile="waveform.png", transparent=True)
If you want to import into Illustrator you will probably want to save the plot as a vector image. Saving it for example as a svg file should work. png is a rasterized format and thus not really suited for a vector program like illustrator.
Cheers!

Hi Greg,
You should pass the transparent arg to the savefig method, not the plot:
plt.savefig('demo.png', transparent=True)
