Context menu on 3D globe

[forman]

From @kjpearson in #325:

Add a right click context menu that contains some useful functions like: tseries_point for that location, define area (allow a polygonal region to be defined by clicking that can be saved/used by other functons eg. tseries_mean, enso).

Specifications

Cate 1 + 2.0.0-dev.1

@kjpearson like so?

[kjpearson]

Something like that. I was thinking specifically of a way to create a more direct interaction with the data as you see it displayed. In particular, "point" operations so, for example, a time-series of the values for the point or a histogram of values over time. I can see that there's the option here to store the location so you can then put them into the operation separately but it would be nice to cut out this step. I think you have more general dataset operations listed here, which is a way to have useful operations easily available, so there is merit in that too.

In the figure you've shown, I imagine subset_spatial to then allow me to click on a series of points until I indicate the end somehow, then go off and do the subsetting. I'm not sure about "open dataset" though. Surely the dataset is already open in this situation?

[forman]

The listed operations all have an input of type geometry (point or polygon). When you invoke them via the context menu, all inputs will be filled by context values. That is

• dataset inputs by the selected dataset resource
• variable name inputs by the selected variable
• geometry inputs by the right-clicked geometry

And you can draw points, polylines, polygons, and boxes now point-by-point:

OK I will wait to try this in person to check if the operations I expect as a user appear in the context menu in different situations.

@kjpearson I'll close this one. Please open a new issue for ideas how to improve the context menu.
