When plotting interactively is it actually possible to update the legend with the current plots while retaining the previous legend settings (position, visibility, etc.) ?
here are some observations on the mpl legend operation: leg = ax.get_legend() #0 OK. but the recommended way to update a legend seems to be using #1 ? leg = ax.legend() #1 OK leg.draggable(True) #3 enables the legend to be moved with mouse. New in mpl1.0.1. OK leg.set_visible(False) #4 hides legend. OK ax.legend(loc=3) #2 defines a legend location. OK but why no locations outside the plotting area ? ax.legend(ax.lines) #5 labels are different by default from #1. ?? ax.legend([]) #6 draws an empty square. ?? leg._loc: #7 allows you to know the legend location. in #2 value is int, in #3 value is a tuple (if the legend has been moved) OK but why is the attribute private ? What to exclude from a legend : Objects without an explicit label (labels starting with _) #8. OK Objects that are not in the viewing area #9. should be default behavior ?? Objects that are not set visible #10. should be default behavior ?? -- thanks, peter butterworth ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
