Hi, I would like the x and y axes on my surf plot to have proportional scales. I am plotting temperature over a 2D plane. I want to visualise the temperature profile but the x and y axes stretch to fit the figure window, stretching the temperature profile.

I want the axes to have the same 'unit:distance on screen' ratio. How can I do this? I have been finding the aspect ratio help not very helpful Thanks

If you want them to have equal scales then

axis equal

Otherwise set the axes DataAspectRatio property. For example,

set(gca,'DataAspectRatio',[10 1 1])

would mean that every 10 units of x is to have the same size as one unit of y -- which would make something of x width 10 and y height 1 into a square.

Hi Walter,

I am plotting some coordinate data and which lies primarily along one axis (y axis). For my plots I wish to have equal axis scales but with a different aspect ratio to reduce white space by adjusting the width of the other axis (x axis). Any idea how to achieve this? The issue is illustrated in the following figures.

Current plot:

Desired (edited in powerpoint):

Of course one could do this manually by changing the aspect ratio of the figure but do you have any Ideas on an easier way?

Regards

Yes, this is another way to set the axes dataaspect property

Hi, i'm using Matlab App Designer.

Unfortunately i have the same problem. But by typing "set(gca,'DataAspectRatio',[10 1 1])" it opens a figure instead of changing the axis scale in my app.UIAxis plot.

How can i have the same scale for x and y axis in my app.UIAxis plot?

Thanks a lot
