Hi all,
I hope this is not a duplicate as I couldn´t find anything similar here.
I´m automating plotting data out of a sample dataset (10 data sets of different sizes within a .txt file).
I run matplotlib 3.5.3 as I get a Matplotlib Deprecation Warning with the newer version.
When I use
pylab.imshow(mat, cmap = cmap)
pylab.axis(‘off’)
pylab.savefig(id + “.png”, bbox_inches=‘tight’, pad_inches=0)
it only saves one data set as an image
when I use
pylab.savefig(seq_record.id + “.png”, bbox_inches=‘tight’, pad_inches=0, dpi=2000)
it saves five.
I tried to set dpi to 5000, it saves all files, but makes the whole script ridiculously slow.
The error I get for setting DPI to 2000 is this one:
Traceback (most recent call last):

encoder.setimage(im.im, b)
SystemError: tile cannot extend outside image
(I shortened the File names to hide my name)
I would like to set the resolution automatically so that it adapts to the size of the input data/resulting graph size.
Thanks for any help!
