python - offset one of matplotlib's legend items -



python - offset one of matplotlib's legend items -

in python's matplotlib, article on newton's method visualize first 3 iterations , lastly 1 in line graph, each iterations shows separate curve. legend labels 'iteration 1', 'iteration 2', 'iteration 3', 'iteration 14'. clarity visually offset first 3 last, either white space or ideally triple dot indicate jump. know of way accomplish this?

you can display 2 legends. first 3 iterations , sec lastly iteration :

l1 = plt.legend(data_for, 3_iterations, loc=[1.01,0.6]) l2 = plt.legend(data_for, last_iteration, loc=[1.01,0.2]) plt.gca().add_artist(l1) # add together first legend

loc allows take position of legend. here on right hand side of figure, , l1 above l2. can modify create clear wish.

for triple dots can add together them plt.text(x,y,"...") x , y coordinate want '...'.

if edit question code, working example, may more precise.

other solution :

lets leg legend object, can move part of legend. instance if want move sec line ([1]) of legend :

l2 = leg.get_lines()[1] l2.set_ydata(np.array(l2.get_ydata())-2) # move downwards of 2 units line (in legend based coordinates)

to move associated text :

t2 = leg.texts[1] t2.set_y(-2)

and frame :

frame = leg.get_frame() frame.set_height(frame.get_height()+20)

for frame, doesn't work me don't know why. maybe work you. alternatively, can utilize :

leg=plt.legend(borderpad=2)

step step, can set legend. can long though, take first option, since can remove frame, won't noticeable.

hope helps

python matplotlib legend
