Issues with the quality difference between plots created in live script and normal script or command window.

Hey there, recently I've updated from 2024b to 2025a and immediately the thing that grabbed my attention was the fact that plots created in live editor and command window are vastly different in resolution and smoothness. I've tried searching for people with similar experience in Matlab answers but couldn't find anything related. Some had issues with the gpu or renderer but my problem is only happening in live editor.

Here's a comparison between a plot created in two environments:

clear; close; clc

t = linspace(0, 2*pi, 1000);
f = 4;
y = 0.8*sin(2*pi*f*t);

figure
plot(t, y)
axis tight

Lower res from live editor:

Higher res from work space:

I've also attached the plots incase uploding them corrupts the quality.

Now the interesting thing is that when I open up the figure window of the same plot that I had created in live editor then suddenly the quality is high again. I tried my luck with chat gpt and grok but they were pulling their results from the same forums that I had already visited so nothing useful was found that way.

No, I'm afraid I'm not seeing that. Is this Ubuntu? Also, your posted images are of different pixel dimensions, so it is not clear how the comparison is supposed to be apples-to-applies.

The only difference I see is the font size, and the size of the overall plot.

Thanku @Matt J and @Walter Roberson for your responses and my apologies if the way I asked my question is causing confusion for you as English is my second language and I'm not exactly an expert in this field.

I'm goning to try to reiterate my question in what I consider clearer language.

The issue I'm facing is exactly what you described all that different pixel dimensions and overall plot size. The plot I get from the live editor enviroment has degraded quality and is pixlated as if its dpi is set to a lower value or its getting rendered by an old machine from 90's. But when I click on open in figure window button meaning this button:

I can see a much better quality plot with way more clarity. It's as if the live editor is giving me a low res png and when I open the figure window I get to see the svg of plot with much higher clarity which I can zoom as much as I like and not loose any quality of picture.

The issue only happens in live editor and nowhere else.

I found this Question where the OP seems to have the same problem (although their problem is way more sever and it seems to happen everywhere regardless of environment live editor or not) with low resolution and pixelated plots in matlab 2025a.

[Walter Roberson]

You should expect lower resolution for the inline plots. The inline plots are inline, and need to fit in a smaller space.

In 2024b this did not happen. I am also affected in 2025b (and 2025a)... yes, under Ubuntu 25.04. MLX plots seem to be rendered at "100%" small size and resolution, looking good at 100% zoom, but if I increase the editor zoom factor and rerun, they keep low-res, pixelated, whereas in R2024b they were rendered at high-resolution when running the script with 300% editor zoom, say.
