Hi,  I don't have the option to Cartesian coordinates x, y between in Power Map options in my Excel??

How can I could get them?

Thanks,

Hi Arianelle,

If you want to create a custom map in Power Map, you need to have:

1. A picture in .jpg, .bmp, or .png file format. For example, a picture of a floor plan or a public transit routes map.
2. Data that relates to the picture that Power Map can plot on your custom map by using an XY coordinate system.

Please Note: If you don't have X and Y data yet, try using Microsoft Paint to record the pixel position of items in your picture and enter them in X and Y columns on your worksheet.

I suggest you refer to the article about how to create a custom map in Power Map.

If your steps are correct, please provide a screenshot and a sample file about your issue. I'm glad to help you check if it works fine in my environment.
