Rotate MAP North South

MikeDereviankin — Sun, 11 Jun 2023 11:18:35 GMT

Hello,

Does JMP have the capability to rotate a map North/South as oppose to simply using Lat Longs? If I have a SHP file within this map would that rotate as well?

Thanks!

I'm not certain I understand what you're asking. Do you mean you want the Y axis to be East/West and the X axis to be North/South? Can you show an example of what you want?

As a first step yes, I would like the axis to be east/west.

However, in terms of interactivity is there no way to just rotate the map or is it confined to lat/long? For instance on a google map we can rotate it.

There are multiple possible answers.

If you are using JMP's maps and projections and axes, north is at the top.
If you are not using a map and projection, you can switch the variables/axes for a 90 degree rotation.
You might also rotate a map 90 degrees the same way, but be careful to align map and data.
If you apply a rotation to transform the data (and map) you can get a arbitrary angle rotation. In this case the axis labels are problematic. JMP does not do rotations for you, not like an interactive google map.

The projection I'm talking about is when you add a background map and JMP switches the axes to use geodesic coordinates. They depend on x axis being longitude and y axis latitude.
