Overlap map/chart

Hello,

I try to add a piece of map behind my chart, the map should be W30, N75, E060.
What I want to achieve is a perfect overlapping of my chart with the map, I mean the location of my points (from chart) to be the same on map. Is it possible?
I know that there are differences between map and chart scale, I tried a lot of ways but I have no idea how to do it. Could you help me, please?
Thank you very much for your help.

If you use the picture as the fill for the plot area then you just need to alter the min/max values of both scales to match that of the image.

You can see that DUB is much closer to actual location by simply adjusting the scale.

Hi Andy, thanks again for your valuable help.
I am not sure why I can not download the file attached, and this is not the first time when I'm facing with but I ignored it by now....
