python - Matplotlib Labels Change Shades Of Grey

Question

I tried running the exact same code on two different architectures (one Windows, one Linux). Same version of Matplotlib. The axes labels are written with different shades of grey (color is default black), as shown in the image. On the same machine, pixels are consistent between runs. The differnt behavior between machines causes bad scores in image comparison tests.

Does anyone know why this could happen, or if there is a way to enforce a certain behavior? I'd be happy also with just a binary color for labels, black/white.

Answer 1

You can "force" whatever colour you like into the labels or anything actually. Assuming you have a figure, you can change:

• spines. (Spines are the lines connecting the axis tick marks and noting the boundaries of the data area aka the borders of the plot)

ax.spines['bottom'].set_color('#dddddd')
ax.spines['top'].set_color('#dddddd') 
ax.spines['right'].set_color('red')
ax.spines['left'].set_color('red')

• ticks (Ticks are the values used to show specific points on the coordinate axis aka the thing you're interested in, I think)

    ax.tick_params(axis='x', colors='red')
    ax.tick_params(axis='y', colors='red')

• label

    ax.yaxis.label.set_color('red')
    ax.xaxis.label.set_color('red')
