change background color in parallelplot

Hi. currently using paralleplot. matlab R2022b.

Didn't find a way to make background color black. By default it's white and not very suitable in my case (lots of lines, so i use line trasperancy). Any suggestions?

thanks

Setting the background color to black sounds like a custom dark theme is being applied. Starting in R2025a you could set the theme to dark.

tsunamis = readtable('tsunamis.xlsx');

figure('Units','normalized','Position',[0.3 0.3 0.45 0.4])
coordvars = {'Year','Validity','Cause','Country'};
p = parallelplot(tsunamis,'CoordinateVariables',coordvars,'GroupVariable','Validity');

theme dark

I don't think it is possible. I tried to look into all the properties of a parallelplot figure (and more in general of a plot figure) using the commands:

%use only after plotting

inspect(gca) %for axis proeperties

inspect(gcf) %for figure properties

but coulnd't find any that changes the plot area background.

Closest i got was to change the figure background with

set(gcf, 'color', [1 1 0]) %yellow

but the plotting area is still white.

well, basically parallelplot uses parallelcoords function. From the jump didn't find a way to adjust background color in it either. Probably I'm just not as skilled as the task requires.

Ok, additional questions that are not as vital, but still:

1) Can I change ticklables and ticksize in Y axes? For example, if column RO.A of table RO is on axis - then lables and ticksize shoud be as unique(RO.A).

2) Color of axes - make it white, so it would be visible on black background (if we are lucky enough to figure it out (: )

3) Switch off hint-box on the chart. Currently it's so big, that it covers the whole axis or even two.

thanks (:

it should be better to post them as separate questions so that you can then accept the answers and also they would show in the questions archive.

Anyways:

Check this for the size: TickSize

For the labels there is this function: xticklabels() and of course yticklabels()

For coloring axes:

set(gca,'XColor','g','YColor','g'); %g is for green
