I'm drawing a simple 3D scatter plot using matplotlib; however, the Z axes label moves outside the bounding box. I tried adjusting the size, using tight.layout, and many more option, but I wasn't able to move the plot in such a way that the Z axes label is visible. Here is my code:

fig = plt.figure(figsize = (7,7), dpi = 200)
ax = fig.add_subplot(projection='3d')

xs = df_final_depth['Power']
ys = df_final_depth['Velocity']
z = df_final_depth['Predicted Depth (um)']
zs = df_final_depth['Ground Truth Depth (um)']

ax.scatter(xs, ys, z, s=70, label="Predicted Depth ($\mu$$m$)", marker='o')
ax.scatter(xs, ys, zs, label="Ground Truth Depth ($\mu$$m$)", marker='^')

ax.set_xlabel("Power ($W$)")
ax.set_ylabel("Scanning Velocity ($mm/s$)",)
ax.set_zlabel("Depth ($\mu$$m$)")
#ax.tick_params()
ax.legend()
plt.show()

enter image description here

Please refer to the attached pictures. Tried tight.layout, changing the figure size and many other options. Can someone advise on solving this issue?

One option is to add a padding to the Z ticks and labels.

So we need to use ZAxis.labelpad and Axes.tick_params and adjust the following parameters :

labelpad The distance between the axis label and the tick labels.

pad
Distance in points between tick and label.

Update/Add these two lines in/to your code and make sure the adjust the values (if needed) :

ax.set_zlabel("Depth ($\mu$$m$)", labelpad=-10) # Updated

ax.tick_params(axis="z", pad=-3) # (+) Added

Output :
