Mathematica - Problem with axes

[LouisPhilippe]

Hi,

I have just started working with mathematica and I am making a few manipulable plots of differential equations. The problem is that when I use the slider to change the value of certain parameters, the size of both axes change along, which makes it difficult to compare graphs.

I would like to have my axes "fixed", meaning they cut each other in coordinate (0,0) and preferably also with a fixed scaling (for example x-axis range from 0 to 10 and y-axis range from 0 to 5)

I don't think this should be too hard but I've spent quite some time looking for this in the help documents, but I just can't seem to find it!

Help would be greatly appreciated!

Try adding a PlotRange option to your Plot

Plot[x^3, {x, 0, 2}, PlotRange -> {{0, 10}, {0, 5}}]

and see if this fixes your problem

Also the option http://reference.wolfram.com/mathematica/ref/AxesOrigin.html" .

The combination of the two fixed my problem perfectly,

Thanks for your help!

Hello Louis-Philippe,

Thank you for reaching out with your issue. It sounds like you are experiencing a common problem with axes scaling in Mathematica. To fix this, you can use the "AspectRatio" option in your plot function to set the aspect ratio of the axes to a fixed value. For example, you can use "AspectRatio -> 1/GoldenRatio" to set the ratio to the golden ratio, which is often a visually pleasing choice. You can also use "AspectRatio -> Automatic" to have Mathematica choose the aspect ratio for you. Additionally, you can use the "PlotRange" option to set the range of your axes to a specific value, such as "PlotRange -> {{0, 10}, {0, 5}}". This will ensure that the axes remain fixed and do not change when you manipulate your plot. I hope this helps! Good luck with your work in Mathematica.
