creating a multi colored graph with respect to the values in y-axis
Hi all, I am a beginner in python. I need to implement a graph with multiple colors in it. In a way, I have a function which varies with respect to time and amplitude. I have time on x-axis and amplitude on y-axis. Lets say the amplitude of the graph is divided into 4 ranges, say 1-3,3-5,5-9, 10-3. I need to plot the graph in such a way that, when the values of amplitude are in a particular range say 1-3, the color of graph should be red. If the amplitude is in the range from 3-5 the graph need to be in color blue etc.., Can somebody guide me on this, how to achive this functionality.

I wasn't able to figure out the usage of boundaryNorm and lc.set_array(z) , in that link. according to my understanding, cmap = ListedColormap(['r', 'g', 'b']) norm = BoundaryNorm([-1, -0.5, 0.5, 1], cmap.N) In the above lines of code, as per my understanding, Listedcolor map, maps the colors r,g and b to specific indexes into cmap i.e cmap(0) represents red, cmap(1) represents blue cmap(2) represents green. for any index greater than 3 a color of blue is returned.. >>> cmap = ListedColormap(['r', 'g', 'b']) >>> cmap(0) (1.0, 0.0, 0.0, 1.0) >>> cmap(1) (0.0, 0.5, 0.0, 1.0) >>> cmap(2) (0.0, 0.0, 1.0, 1.0) >>> cmap(3) (0.0, 0.0, 1.0, 1.0) In this context, I was not able to understand what does boundaryNorm does. We have 3 colors and we are using 4 values as argument in boundaryNorm. [-1, -0.5, 0.5, 1], the comment reads slope of 'z' is being mapped to the values in boundary norm. How is it handled. Does the function call " lc.set_array(z) " does it ? what is the exact use of linecollection.set_array(z) in this context. Thanks, Ravikanth -- http://mail.python.org/mailman/listinfo/python-list

Just wanted to know how to go about when I have to do my color mapping not only with respect to range of values on y-axis but also based on some other conditions as well. i.e, say ( range && && ) where condition1 could be occurance of some event say, a flag1 is set true and condition2 may be another flag2 set to false. Just wanted to use my color mapping not only based on boundaries but also on occurance of other events as well. In this context do i have to modify the source of BoundaryNorm in matplotlib function...?? Can you give me some insights into this.

trouble creating tooltips using Wx in Tk canvas
Hi all,
Hi all,
I am having a trouble creating tooltips. I am trying to embed a
matplotlib graph inside a TkInter canvas. After some search over the
net, I found out a way to create tooltips using the WXbackend.
But when I embed my matplotlib figure inside a Tk and the tooltips
are not getting displayed.
The error I am getting is below.
Traceback (most recent call last):
File "U:\graphing_tool\plotinsideTkInter\plotInTk.py", line 12, in
tooltip = wx.ToolTip(tip='tip with a long %s line and a newline\n'
% (' '*100)) # needs to be added to getover the bug with tooltip.
File "C:\Python27\lib\site-packages\wx-2.8-msw-unicode\wx\_misc.py",
line 771, in __init__
_misc_.ToolTip_swiginit(self,_misc_.new_ToolTip(*args, **kwargs))
PyNoAppError: The wx.App object must be created first!
I am not able to figure out the reason. I am trying to use IDLE for
running the script using python 2.7. I tried running from commandline
as well but still i face the same error. Following is the piece of
code I have used.
I created a simple 'sin' wave using matplotlib. and a button. Added
them to a TkFrame.
and then binded the code using
self.f.canvas.mpl_connect('motion_notify_event',_onMotion)
to '_onMotion' function, where I am printing the toooltip.
Can somebody please help me solving the issue.
Code I have used is below.

Thank you Ian for your insights to me on this.
I will migrate to wxPython to achieve the functionality.

show() in pylab doesn't work if used twice
Hi all, I have been using python for just over a month now. I am writing a program to plot some graph using the show() twice in the same program. The code snippet is shown below. I am trying to plot a simple x vs y using ax.plot() then I get a figure displayed. I close the figure displayed and then the execution proceeds. Now If i try to call show second time with the updated values of x and y, the second figure does not appear on my desktop. but the second call to show() appears to work as the code also printed 'passed the second show' as well Can someone help me figure out what the problem here is.why is the second figure not coming up on the desktop. I am using python 2.7 . from pylab import * import scipy import pylab as pl import matplotlib.pyplot as plt fig=pl.figure() ax=fig.add_subplot(111) x=arange(10) y=x*2 ax.plot(x,y) show() print 'passed the first show()' x=arange(10) y=sin(x) ax.plot(x,y) show() print 'passed the second show()' -- http://mail.python.org/mailman/listinfo/python-list
