Adapt latitude and longitude labels when using "zoom to rectangle"

[Jens-Uwe Grooß]

If in the top view (cylindrical or stereographic projection) the "zoom to rectangle" button is used to zoom the section, the labels showing the latitudes at the frame should be updated. Currently it seems that the former labels are kept at the previous location in map coordinates

This problem cannot be reproduced. Today it seems to work.

This issue is client side, the image by the server has not any labels.

If you look what happens on zooming in slowmotion I think the order is, by using auto-update

• rectangle drawn
• new map drawn
• old map cleared
• old labels become cleared
• new map drawn
• new data drawn
• labels drawn

I definitly see old labels sometimes separatly cleared.

This all in all looks like we could optimize that a bit.

I move this for now to 1.7.0 because we could optimize erase on gui site.

When clicking the "redraw map" button, the labels seem to be shown correctly.

[Joern Ungermann]

Matplotlib in combination with basemap often has "hickups" like that when moving or zooming. I believe that is the main reason why there is the redraw map button. I never managed to reproduce these kind of issues reliably and from looking at logs when that was happening, I believe that MSS is not at fault here.

this is a seldom matplotlib issue
