Plots in Jupyter: Mathematica vs Sage

Below are four versions of a same plot in Jupyter notebooks in JupyterLab:

  • light theme vs dark theme
  • Mathematica vs Sage, using the Wolfram Language kernel and the SageMath kernel

To reproduce, either use the notebooks: mathematica | sage, or use the following code snippet:

f = 8.252e-5 - 0.035e-10*x
I = (0, 1e5)
labels = ["altitude in meters", "force difference in newtons"]
plot(f, I, axes_labels=labels)

and in JupyterLab, select light or dark via the "Settings > JupyterLab Theme" menu.

Light theme

Left: Mathematica. Right: SageMath.

Dark theme

Left: Mathematica. Right: SageMath.

Observation

In the SageMath plots,

  • the font size is inconsistent between the axis labels and tick labels
  • the white background does not include the axes or tick labels if the plot does not extend to an area covering them; as a consequence, in dark mode,

    • the y-axis label and y-axis tick labels,
    • the x-axis, x-axis label and x-axis tick labels,

    are black on a black background, and cannot be seen.

Question

Could i make the background permanently opaque, and permanently change the font size to something more reasonable like Mathematica has for reference?

This answers only the question about the font size: use the option axes_labels_size in plot() to set the relative size between the axes labels and the tick labels. The default value is 1.6, which is fine for LaTeX-typset axes labels, but may be too large for non-typeset ones. Use axes_labels_size=1 to get the same size as for the tick labels. See axes_labels_size and show options.
