# how to given numbers to any lines with equal intervals (varying width of interval) as in axes?

Math123 shared this question 2 years ago

Based on your (pseudo) "description," it's not clear what you want..

Maybe :wink: something like in the appendix.

Thank you so much @rami. I am really happy to see you, as always you solve my problem.

@rami is it also possible to displace the origin. In the attachment i have displace the origin but points and grid does not displace with them. Pls check and suggest solution.

Once again thanks.

I think this is not possible (sure not possible for the regular axis). And I think too: this make no sense.

But you can define a new free point and then make f and g depending from this new point. Then change also l1 to l5 and maybe more.

Thanks @rami for your support as always. If there is any possibility for origin displace pls do share.

Please tell me what you need it for (so I understand the purpose)

I need to show transformation when bases are different and also both coordinates systems do not have same origin. Also i need to show frame of reference of different moving observers (Like axes moving continuously).

Perhaps this is clearer in 2 separate windows (?)

AND/OR

You need something like this

Hi rami

thanks for this excellent file .

how i can find map for functions or curve in cartesian coordinate to new coordinate in this file or inverse?

Unfortunately not one of my core competences.

but here are 2 example from GGBTunbe (transformation, matrices)

Hello @rami, How to add simple numbers in new axes other than coordinates according to x-y axis as in attached.

this?

Thanks rami for your always support. Do you pls explain how the definition of numbering work .

Sequence(Text("" + (XL_2(n)), XL_3(n) - UnitVector(Vector(O, X)) 10pixX + (0, 10pixX)), n, 1, Length(XL_2))

1

Each number in XL_2 is create as text at position from XL_3. Both elements are addressed with the same (synchronous) index (n). The position (from XL_3) is moved a few pixels in the direction of O and y-axis. The length of 1 pixel is calculated in pixX. If the character size of XL_4 is changed, the factor 10pixX must be adjusted.
