not sure it’s the right place to ask the question, I’ll be happy to ask elsewhere if it’s the case.
The following code is based on this blog post on Medium.
I’m calling basemap through PyCall and when I execute the following code I get the right results, but it triggers a figure. I was wondering how to prevent the figure from appearing. The figure appears when the line
poly_paths = m[:drawcoastlines]()[:get_paths]() is executed.
Thanks for any help!
using PlotlyJS using PyPlot using PyCall const basemap = PyNULL() copy!(basemap, pyimport_conda("mpl_toolkits.basemap", "basemap")) m = basemap[:Basemap]() function polygons_to_traces(poly_paths, N_poly) """ pos arg 1.
