Patches not present and title on the wrong location

[suuuehgi]

trafficstars

Neither the label patches with their label, nor the axis title is present in the output .tex file.

I think the former is related to #467, regarding the latter, the title itself is present within the output but located at the very bottom left corner at (1,1) and thus not visible or misplaced.

MWE

Z = np.random.randint(0,2,size=(10,10))

fig, ax = plt.subplots(figsize=(9,9))

im = ax.imshow(Z,origin='lower',cmap='coolwarm')

colors = [ im.cmap(im.norm(v)) for v in [0,1]]

patches = [ mpatches.Patch(color=colors[ll], label=l ) for ll, l in enumerate(['Label 1', 'Label 2']) ]

ax.legend(handles=patches, bbox_to_anchor=(0, 1), loc='lower left', borderaxespad=0.1, frameon=False)

ax.set_title('My Title\n'+r'$\chi = 2, \quad \tau = 5$', loc='right')

plt.tight_layout()
# fig.savefig('bug.svg')
tikzplotlib.save('bug.tex')
