Gnuplot: default background color terminal “qt”

Question

I'm using gnuplot 5.0 with term qt - Qt terminal. Now, when I plot (or splot) whatever I want I have always to follow this post command

set object 1 rectangle from screen 0,0 to screen 1,1 fillcolor rgb "white" behind

to set the background color to white. In fact, as default background color I have "black", so anytime I plot something, e.g.

set term qt
set pm3d
splot sin(x*y)

the output window has a black background, as below

Now, if i export the plot, it shows correctly the white background,

Since having an interactive term (such as qt) but can't interact with it is really annoying, the only possible way is to set manually the background color with the command set object or with the "Terminal configuration" tool, which anyway does not allow to change the color definitely

I've looked around, but nobody seems to know whether there's a command to change definitely the background color in qt terminal, so anytime I plot with tis term I have to change it manually.

Hope someone knows the solution! Thx!

Create file ~/.gnuplot and add there what you want to be in preamble. — user4489658

When you save a graph

gnuplot > save "test.plt"

and you open it, you will see that the file contains ALL the value for all the possible option for your graph. Those information are the default of your graph and gnuplot under linux reads them in an hidden configuration file locate in the home and called .gnuplot

I suggest you to import to read this it gives you a nice one to use. Using the above one as a model I created my personal one which is available here
