App Designer: UiAxes window size changes when zooming or maximizing the application

Hello,

First, I wanted to say that I changed DataAspectRation and PlotBoxAspectRation to 1,1,1 and DataAspectRationMode and PlotBoxAspectRatioMode to manaul because I want a linear plot.

Linear Plot with manual mode: Non Linear Plot with auto mode:

In Auto mode, the plot size is perfect, but it becomes nonlinear. In manual mode the plot size is smaller but linear.

Also, when I zoom out or maximize the application, the plot size changes, sometimes the plot becomes very small and goes to the right left corner. The behavior is very unpredictable.

The chart should have a fixed size and be as large as possible.

The next problem is the delay when I zoom. It looks like the plot wants to change to the initial zoom position for 1 second.

Even if the plot is perfectly snapped, like in the next picture, I can't zoom out and in, I have to move the plot first and then zoom out and in.

I have a video for you to better understand all the questions.

You can see when I maximize the application for a second, the size of the plot gets smaller, and eventually it takes on that size and doesn't change.

You cant see this in the video, i coudnt reproduce it :/

Also i have all settings for the UIAxes listed here:

Do u have any idea, how to fix that?

(I use MATLAB R2021a.)

Thanks!

Are you using the gridlayout system?

It could just be slowness of the ui system, and can't be helped...

If you're asking about when you set DataAspectRatio, the plot area doesn't fill all the available app area, then, that is asking alot...if you really need to do that, you'll probably have to define a custom resizeFcn that measures the available size of the area, and compute XLim and YLim for your axes that match the aspect ratio of the available area, so that when it asserts DataAspectRatio it wil be able to fill the area.

Hello Alex,

Yes, I use the grid layout system, but it doesn't work so well :D and the available app area should be filled automatically. Thanks for the idea, I was hoping for a simpler solution.

Yea, but think about the whole purpose of being able to set DataAspectRatio, which is to display things squarely independently of the XLim and YLim you choose...so actually instead of what I suggested above, you can just not use DataAspectRatio and compute the limits manually such that when filling the area (default behavior) you will have the correct aspect ratio.

If you don't actually need the axes, one option could be to set the axes visibility off, and color the axes background to white. Wouldn't work if you actually wanted to display the axes.
