I am trying to add gv.Labels on top of the gv.Points, while I found both ylim and yoffset don’t work. Is there an alternative way to set them in the Geoview plot?
In this demo, 10 random-gv points with the same Latitude (0) will be generated by clicking the button. The gv labels are used to identify the point IDs. I would like to set “ylim=(-10,10)”, without gv labels, it works, while by adding gv labels, it does not work. Also, Is there a way to set offset of the gv labels, just like what we can do with hv.Labels? See my demo code below. Thanks in advance.
