tooltips using pyplot

Hi all,

I need some help creating tooltips using pyplot figure rather than the exisiting pylab example as in the link below

http://www.mail-archive.com/matplotlib-users@…813…ourceforge.net/msg00954.html

Well there is a specific reason for this. I am trying to write an application which needs to call show() twice. matplotlib 1.0.1 solves this issue by using show() in pyplot.

The code snippet i’ve used is

from pylab import *
import scipy
from wxPython.wx import *
import wx
import matplotlib.pyplot as plt
application = wxPySimpleApp()
tooltip = wx.ToolTip(tip=‘tip with a long %s line and a newline\n’ % (’ '*100))

fig=plt.figure()
ax=plt.gca()
x=arange(10)
y=x*2

plt.plot(x,y)
plt.xlim(-2,15)
plt.show()

print ‘passed the first show’
x=arange(10)
y=sin(x)
plt.xlim(-5,10)
plt.plot(x,y)
#print plt.get_current_fig_manager().canvas.SetToolTip(tooltip)

plt.show()

print ‘passed the second show’

As per my observation, we need not create a new figure everytime we use pyplot. Just plt.show() serves the purpose.

In case of using pylab show() then we need to call it once at the end of the program or create a new figure everytime previous figure is closed and it works too.

Please correct me if my observation is wrong.

I am stuck at the point at tooltips now. How should I create tooltips on a figure plotted using pyplot.

My program says there “FigureCanvasTkAgg instance has no attribute ‘SetToolTip’

plt.get_current_fig_manager().canvas.SetToolTip(tooltip)

for the current figure manager but in pylab equivalent

from pylab import get_current_fig_manager as gcfm

gcfm().canvas.SetToolTip(tooltip)

works.

Please guide me how to go about this issue.

Just a quick comment, according to your error message, you have a TkAgg figure, not a WxAgg figure. Maybe you should try forcing a particular backend using “matplotlib.use(‘WxAgg’)” at the beginning of the program?

I haven’t read through the rest to comment on the validity of your observations about show().

You are going off the rails right here. Don't try to mix pyplot and direct use of a gui toolkit. Just don't do it. Please. If you want to use a gui toolkit directly, then start by understanding the embedding*.py examples in the user_interfaces subdirectory of the matplotlib examples.

My program says there "*FigureCanvasTkAgg instance has no attribute

plt.get_current_fig_manager().canvas.SetToolTip(tooltip)
for the current figure manager but in pylab equivalent
*from pylab import get_current_fig_manager as gcfm*
*gcfm().canvas.SetToolTip(tooltip) *
works.
