# How to make x-y axis on two lines other than 2D-plane?

You can create a pair of lines, rotated around the Origin, but if you want them to be your "new" axes, then you must refer all the equations of the objects you create to this new pair of lines.

Sorry, I forgot the file - if this is what you need.

See the OnUpdate tab of angle alpha.

Thanks for reply simona. I have attached these. But i want numbers, tick marks and grid as in normal axes. But with different interval size of numbers.

Your axes are not an orthogonal system, though.

If you drag the points, the angle between them doesn't stay as 90°.

Do you want an orthogonal system?

This works on an orthonormal system. Drag the slider.

Use this example as a reference to create the same objects for your possible non-orthogonal axes

Thanks simnoa Riva. I don't want just for orthogonal system. I want this to be for non-orthogonal system also. Bases can be at any angle and as well as for different origin.

Perhaps this possibility comes closest to your ideas.

Hello rami, I want any non-orthogonal cartesian system. two lines at any angle have numbers and tick marks.

Thank you very much in advance.

Hello Team. Need you help in this. Thanks

Dear Team need your help in this.

Build your own axes [1] [2]?

Thanks @Loco pls give the solution as in attached. it does not intersect point and grid. also add number in new axes.

Pls @rami and GGB TEAM look into this and give the solution.

Dear Team , This is not the problem of my solution. Pls have a look and suggest solution.

Thanks
