Very good. Hope it will be possible to manage horizontal and vertical zoom independently too.
Unfortunately I can’t install gnuplot because of conflict with Qt5. Ill wait for ngspice 32.
Just updated to 5.1.8 and white background of simulation plot is still unavailable. Or I missed it.
Any hint to obtain white background in stable release?
He was talking about standalone ngspice, not the ngspice interface built into KiCad:
https://sourceforge.net/projects/ngspice/files/ng-spice-rework/33/
Then I have two questions:
-
is there any way in 5.1.8 (the current stable release) to have white background in simulation plot?
-
given that in nightly this feature is available when it will be available in a stable release? Hope before in version 6.
I’m sorry. I do not know enough to answer those questions. Maybe someone else can?
5.1.x releases are bugfix releases, no new features.
The nightly builds are daily development “releases” which will lead to the next stable x.y version which at this time will be 6.0. So all new features which are now available in the nightly builds will be in 6.0 but not earlier.

Any idea on when version 6 will be available?
I heard some rumors about FOSDEM 2021 being target date so February 2021
I think it was for rc1, but the history shows that we shouldn’t hold our breaths, and even after rc1 the final release can take several months. But of course this time it may be different, and if people test and report bugs diligently it will be sooner.

Thanks for answers .
I seldom use the simulation (preferring LTspice) but, on the few occasions when I do use it, I save the Image and use an external program to Invert the colors… That gives me something I can print on paper…
I know that LTspice is good in simulation but this need to draw a copy of schematic in LT too
Good idea waiting for the feature in KiCad.
Here’s a tip:
See the Blue comments in attached image. Thus, no need to
build the schematic in LTspice. Simply use the Netlist from Kicad…
EDIT: No need to paste the code if running LTspice from Kicad (as long as
you saved the Netlist as .CIR) 
This is a real improvement, LT become like a KiCad plugin.
I’m using KiCad in Linux then the steps are slightly different but I simply open KiCad netlist using LTspice installed in Wine ad all works. Thanks a lot.
Now I’ll search for the right command to run simulator from KiCad.
I’m using a Mac and it shouldn’t be much different. Simply grab the location of the LTspice app and paste it into the cmd field…
Just a quick comment on this technique:
If you attempt this in the exported PNG due the export of the text being “contaminated” by black, the resulting plot gets all the text smeared as if the letters had been eroded.
No manouver of changing colours solve this problem.
I’m not clear on what you’re saying…
I just ran a Kicad Schematic, Exported the Netlist as .CIR and ran the .CIR in LTspice.
No problem… I also ran it in Kicad with Black, then with White backgrounds, No problem (and, Kicad colors have nothing to do with LTspice).
I don’t know what KiCad had 4 years ago when this thread started, but KiCad V8 has: Spice Simulator / View / Dark Mode Plot and turning this checkbox off makes the plot background white.

Hi @csrabak
Useful information can be found in old Forum threads, but there is little point in reopening a four year old thread to discuss a technique for subject that is no longer relevant due to program upgrades.
Time to put this thread back to bed.
