clabel manual

David_Arnold · February 6, 2010, 7:01am

Hi,

I'm trying to get manual labeling of contours to work:

import numpy as np
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt

delta = 0.025
x = np.arange(-3.0, 3.0, delta)
y = np.arange(-2.0, 2.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = mlab.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)
Z2 = mlab.bivariate_normal(X, Y, 1.5, 0.5, 1, 1)
# difference of Gaussians
Z = 10.0 * (Z2 - Z1)

plt.figure()
CS = plt.contour(X, Y, Z, 6,
                 linewidths=np.arange(.5, 4, .5),
                 colors=('r', 'green', 'blue', (1,1,0), '#afeeee', '0.5')
                 )
plt.clabel(CS, fontsize=9, inline=1, manual=True)
plt.title('Crazy lines')

plt.show()

On my macbook, clicking with the touchpad does not seem to work.

Any ideas?

David.

This is a known bug, and I think I fixed it in the svn. Meanwhile, you
may use the monkey patching.
Insert these lines in your script (before you call clabel).

import matplotlib.blocking_input as blocking_input
def mouse_event_stop(self, event ):
    blocking_input.BlockingInput.pop(self,-1)
    self.fig.canvas.stop_event_loop()
def add_click(self, event):
    self.button1(event)
def pop_click(self, event, index=-1):
    if self.inline:
        pass
    else:
        self.cs.pop_label()
        self.cs.ax.figure.canvas.draw()

blocking_input.BlockingMouseInput.mouse_event_stop = mouse_event_stop
blocking_input.BlockingMouseInput.add_click = add_click
blocking_input.BlockingMouseInput.pop_click = pop_click

JJ,

Very nice repair, as this works precisely as it should. I use this tool in Matlab all the time when teaching multivariable calculus.

The above version has some typos (while it works it had some
side-effects), here is the corrected one.

-JJ

import matplotlib.blocking_input as blocking_input
if blocking_input.BlockingMouseInput.add_click ==
blocking_input.BlockingContourLabeler.add_click:
    def mouse_event_stop(self, event ):
        blocking_input.BlockingInput.pop(self,-1)
        self.fig.canvas.stop_event_loop()
    def add_click(self, event):
        self.button1(event)
    def pop_click(self, event, index=-1):
        if self.inline:
            pass
        else:
            self.cs.pop_label()
            self.cs.ax.figure.canvas.draw()

    blocking_input.BlockingMouseInput.mouse_event_stop = mouse_event_stop
    blocking_input.BlockingContourLabeler.add_click = add_click
