[Matplotlib-users] embedding a plot function in existing wxapp GUI, problem replotting
Hi,
We have been working on a python wx app GUI for finding and selecting metadata
(lots of lists and check boxes) from a test (that later fetches SQL
time-history data for further processing in LabView or elsewhere).
As an afterthought, we decided to add in a small function that would allow
previewing (plotting) of time-history data based on the selected metadata. The
objective is to have a window pop up with the plotted time history data and
allow the user to zoom, scroll etc, without closing or exiting the original GUI
for selecting the metadata. The reason I want a pop up window is because I
don't want to change the original metadata selection GUI (it's too complicated)
What I've done so far is:
Added a button to the metadata GUI called plot. In the OnPlotButton event
handler I embedded the plotting code.
The plot button works fine when I click it the first time. However, problems
occur when I decide to plot a different set of data (without starting over the
metadata GUI). I'd like to choose some new metadata, then click on the plot
button again. But as of present, this causes the figure to show a gray image
(no lines plotted) and then both GUIs hang up. I've tried closing the figure
manually prior to selecting new metadata and clicking on plot but it still
causes the metadata GUI to lock up.
Based on what I've been reading regarding MPL, it seems that the matplotlib
show() function causes another instance of a GUI loop to remain suspended.
Is there any way to get the pop-up figure to show the time-history data and
remain interactive (zoom, scroll, etc) and be able to re-plot or replace the
current plot? I thought about using the draw() function but I couldn't get it
to pop-up the figure. Also, if I'm not mistaken, the draw() function doesn't
allow for interactive control?
I think this issue is similar to the issue described here:
http://mail.python.org/pipermail/pythonmac-sig/2005-March/013365.html but I
can't seem to find a simple solution, without embedding the plot figure
directly into the existing GUI (not something easy to do as I'm not a very
experienced Python programmer)
Please let me know if anyone can help.
Here is my code:
def OnPlotButton(self, event):
global SelTestID, SelRunList, SelEventID, SelChanList, SelCycList
if self.notebook.GetSelection() == 0:
SelTestID = self.listCtrlStatus.GetItem(0,1).GetText()#.strip(,
).split(, )
if self.listCtrlStatus.GetItem(2,0).GetText() == Event Selected: :
SelRunList =
self.listCtrlStatus.GetItem(1,1).GetText().strip(, ).split(, )
SelChanList = []
SelCycList = []
SelEventID =
self.listCtrlStatus.GetItem(2,1).GetText()#.strip(, ).split(, )
else:
if self.listCtrlStatus.GetItem(1,1).GetText() == All:
SelRunList = []
for iRun in range(self.checkListRuns.GetItemCount()):
SelRunList.append(str(self.checkListRuns.GetItemText(iRun)))
else:
SelRunList =
self.listCtrlStatus.GetItem(1,1).GetText().strip(, ).split(, )
SelChanList = self.checkListBoxChans.GetCheckedStrings()
if self.listCtrlStatus.GetItem(3,1).GetText() == All:
SelCycList = []
else:
SelCycList =
self.listCtrlStatus.GetItem(3,1).GetText().strip(, ).split(, )
SelEventID = ''
elif self.notebook.GetSelection() == 1:
SelTestID = self.listCtrlStatus.GetItem(0,1).GetText()#.strip(,
).split(, )
SelRunList = self.listCtrlStatus.GetItem(1,1).GetText().strip(,
).split(, )
SelChanList = []
SelCycList = []
SelEventID = ''
##VTS.MsgBox(Test,eWO: + SelTestID + \nRuns: + str(SelRunList)
+ \nChans: + str(SelChanList) + \nCycles: + str(SelCycList) + \nEvent:
+ SelEventID)
#cleanup to prevent memory leak if previously plotted
plt.close('all') ##make sure all figure windows are closed
fig = []
ax = []
#prep data for plotting plotting
myeWO = str(SelTestID)
nRuns = len(SelRunList)
myRuns = []
for iRuns in range(nRuns):
myRuns.append(str(SelRunList[iRuns]))
nChans = len(SelChanList)
myChans = []
for iChan in range(nChans):
myChans.append(str(SelChanList[iChan]))
dataLst = VTS.FetchSQLRunDataByName(myeWO, myRuns, myChans)
lenData = len(dataLst)
dataArry = np.zeros((lenData, nChans + 1))
for iPoint in range(lenData):
dataArry[iPoint] = dataLst[iPoint]
#begin plotting
fig = plt.figure(1)
ax = fig.add_subplot(111)
myPlotLines = []
for iChan in range(nChans):
tempLine, = ax.plot(dataArry[:,0], dataArry[:,iChan+1], label =
myChans[iChan])

I would agree with Chris that you should bite the bullet and embed it. That you are new to Python shouldn't be too much of a problem if you follow the recipe linked there. Note that the top links on that page are broken, but if you go to one of the last links: http://www.scipy.org/Matplotlib_figure_in_a_wx_panel ...this works. And if you need help getting it going, people can help you. Don't worry about all the fancy graphing stuff there, the draw method could have just been: def draw( self ): Draw data. if not hasattr( self, 'subplot' ): self.subplot = self.figure.add_subplot( 111 ) self.subplot.plot( [1,2,3]) and you could lose all the numpy geometry code and it would have been a boring plot but a simpler block of code. :D Che -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

I know it's badly out of date... I'd like to embed it but I'm not quite sure where to begin... Do you think a simple solution like calling it from the system command line will open the plot in a new instance, so that the metadata GUI wont be hung up by the show()? I'd have to pass the selected metadata to a temporary file on disk. It's a bit of a dirty method...
