Dynamic legend labels with space in it #1632
Description
Description of the problem
I would like to display the number of dots in the legend. This number is not static it comes from a data file.
However, I don't understand how to do it with space in the text. The label='"this is my data"' works only for static data.
May I help on this ?
Full code that generated the error
Works
# Legend labels
label_restricted= "Data_requering_owner`s_authorization_"+str(data_restricted.size//3)+"_points"
label_open = "Available_data_"+str(data_open.size//3)+"_points"Does not work
# Legend labels
label_restricted= "Data requering owner`s authorization "+str(data_restricted.size//3)+" points"
label_open = "Available data "+str(data_open.size//3)+" points"Rest of the code
# Create map with shorelines and borders
fig = pygmt.Figure()
fig.basemap(region=region, frame="ag", projection="M25c")
fig.coast(shorelines="1/0.5p,black", borders="1/0.5p,black")
