wxMaxima on Windows (MS Surface)

When using wxplot2d ... on a MS Surface device (which has a high resolution display), the font size in the plot is very small. The font size should be bigger, perhaps adjustable somewhere in the settings.

You can do that, by setting the Gnuplot options via gnuplot_preamble, e.g.

wxplot2d(x,[x,1,10],[gnuplot_preamble,"set tics font \", 30\"; set xlabel font \",20\"; set ylabel font \",20\";"]);

This sets the font size of the numbers (tics font) to 30, of the x and y label to 20.

That helped me, thank you! And i can insert a line in wxmaxima-init.mac to have a font size as a standard setting with set_plot_option.
If I use a bigger number for font size, I get very weird output (as if the font size is 10 times higher than indicated). And this seems to be dependent of the hardware. Font size of 30 works on my Desktop with fullHD resolution. On my Surface Pro 10, the font size of 21 seems to be the highest, which is possible. With font size of 22, the plot is no more visible, see attachment.

I tested this (the very big fonts sizes) on the wxMaxima version 22.04.0, which comes with Maxima 5.46.0. Here, it is possible to set large font sizes without the weird output.

Thanks for your feedback. This is a Gnuplot issue - or one of the font libraries, they use. Maybe that bug was not present in the older version of Gnuplot, which was incuded in Maxima 5.46.0. It was already reported as: https://sourceforge.net/p/gnuplot/bugs/2611/

But I tried it now with their current release (6.0.1) on Windows - it is still there.
