The output is slightly different from running the original code with these changes, but the result is the same. this tracback is:

Traceback (most recent call last):
File "/Users/allengordon/Documents/workspace/pgsolar/wxmplot/examples/stripchart.py", line 110, in onTimer
t2, y2 = next_data

File "/Users/allengordon/Documents/workspace/pgsolar/wxmplot/examples/stripchart.py", line 110, in onTimer
t2, y2 = next_data
TypeError: cannot unpack non-iterable function object

running the somewhat modified code as is to plot one trace in real time works just fine. However, I added some code to plot two traces and get "TypeError: 'NoneType is not subscriptable'. The code I changed is:

def onTimer(self, event):   #5

    self.count += 1
    etime = time.time() - self.time0
    self.tmin = float(self.time_range.GetValue())
    t1, y1 = next_data()
    _**t2,y2 =next_data()**_    #new
    self.tlist.append(t1)
    _**self.tlist.append(t2)**_   #new
    self.ylist.append(y1)
    _**self.ylist.append(y2**)_    #new
    tdat = np.array(self.tlist) - t1
    mask = np.where(tdat > -abs(self.tmin))
    ydat = np.array(self.ylist)

The output is this:

Hi, is it possible to resize a PlotPanel?

Good morning !

matplotlib.nxutils has been removed from matplotlib since the last 1.3 versions
http://matplotlib.org/1.3.0/api/api_changes.html

Thank you for the project

Yannick

I am new in using wxmplot and find it comfortable. There is one thing I cannot get run: it is the plot configuration. When I choose "right mouse->config" on the plot or "main menu->options->configure plot" nothing happens. It even doesn't work for the simpliest example "WXMPlot Demo". The zoom methods in the context menu work fine.
I guess it has something to do with my OS/installation. I am using Canopy Enthought on Windows 7 and installed wxmplot via pip install.
Grateful for any help.

serious bug! Only auto-scaling actually sets the y limits correctly..

setting N_levels to N actually shows N-1 levels. Also, setting N_levels seems to also mess up when the color table is reversed.

Trying to run cmy_image.py fails with

Traceback (most recent call last):
  File "cmy_image.py", line 35, in <module>
    subtitles={'cyan':'Cyan Image', 'magenta': 'Magenta Blob', 'yellow': 'other'})

    self.set_subtitles(**subtitles)
TypeError: set_subtitles() got an unexpected keyword argument 'cyan'

it's too clunky to not have "unzoom" from a pop-up. Also on popup: Zoom/Lasso, Save Image, Rotate

on at least one machine, reverse table for imageframe is broken....

I have a program that crashes when I use the Zoom feature. Zooming in or out does not work. I traced the problem back to the function set_viewlimits in basepanel. The problem is that the function, to my knowledge, doesn't exist.

Is this a callback I am supposed to set in order for zoom to work?

I was going through the demo.py example, there is an update_limits option in the update_line function (line 283) that does not seem to be found anywhere in the documentation. I also don't see any difference with it set to either value. Am I missing something? Please, let me know.

Is it possible to plot data like temperature (-25, 40) vs power(0W, 10kW) like this http://matplotlib.org/examples/api/two_scales.html

I runned the example given for multiplot on Spyder. The first time I executed my program, it is okay, but the second time I have this mistake :
` wx.Frame.init(self, parent, -1, title, **kws)

PyNoAppError: The wx.App object must be created first!`

got this error building wxpython after cloning the project and running pip install. I had to install wheel package separately to prevent use of legacy. I also ran pip install wxpython which failed as well

note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> wxPython

note: This is an issue with the package mentioned above, not pip.

As matplotlib handles only a subset of latex, it's easy to break labeling, and errors are not handled gracefully.
In the code, relabeling is both too spread out, and then consolidated into config.relabel(), making it hard to detect what label is causing the error.

Should probably switch to strict use of config.set_xlabel(), config_set_title(), etc. A popup warning message should occur for
non-compliant latex labels.

A scatter plot that supports lassoing as an alternative to zooming should be added to PlotPanel (or made a separate ScatterPlotPanel?). The configuration for this should include the plotpanel configuration, minus line/trace settings, and plus circle size, normal color and highlighted color.

Are there any plans to support wxPython Phoenix (3.0+) and Python 3.4+?

Can't see any hints on this in method zoom_leftup

for image_display, toggling "Label Contours" seems to ignore the state of 'reverse color table'.

I have written wxmplot panel which is linked to the selection made by user. The plotting feature works perfectly fine. However when I try to zoom in into the graph, it zooms into the graph created by previous event. In other words the everytime I make new selection the graph is not being updated

in the "configure plot" frame, both "colors and line properties" and "text, labels, legends" have the checkbox "show legend", their function are same, but when i click one of them, the other won't change state accordingly. I think it should behave this way.

Receiving the following error in windows 11 Enterprise
Tried python versions: 3.8, 3.9, 3.10 with same result

File "C:\Python38\lib\site-packages\wxmplot\basepanel.py", line 519, in gui_repaint
and isinstance(self.canvas.figure._cachedRenderer, RendererWx)):
AttributeError: 'Figure' object has no attribute '_cachedRenderer'

Problem goes away when I comment out the following code block in basepanel.py

    if (wx.Platform == '__WXMSW__'
        and isinstance(self.canvas.figure._cachedRenderer, RendererWx)):
        bmp = bmp.ConvertToImage().ConvertToBitmap()

plot/oplot() should allow a couple choices of 'dashed' styles, using line.set_dashes()

axes.panel.lines[i].set_dashes((on, off)) 

the default seems to be (6, 6),

I think having (4, 1) and (12, 5) would offer clear contrast

Hi,
Reproducible with:

1. left click in plot
2. click zoom out
   2.1 everything still clickable
3. left mouse down in view
4. mouse click breaks

Traceback:

is this even a wxmplot bug?

PS: Didn't had the time for a PR on doc :(

Hi.
I am working adding these modes, that we can find with matplotlib. With the current program, it seems to me that I cannot add zoom only on X/Y functions in the zoom functions which already exist, so I will add two new cursors modes for these functions. Currently I am working on zoom on x mode, I am trying to create a rectangular box with its height equal to the height of the graph, but I don't know how to get back these values.
For pan mode, I tried to use the pan function from the Navigation toolbar from matplotlib.

Sorry, I have zero experience in reporting issues.

But I believe I've found an error > if you succesfully draw a plot with wxmplot.PlotPanel.Plot() using the use_dates=True option and then you want to later update it with wxmplot.PlotPanel.update_line() and update_limits=True you'll get an error:

TypeError: '>' not supported between instances of 'float' and 'datetime.datetime'

The error I believe stems from config.py the set_viewlimits() function. More specifically I think it goes wrong here:

                        else:
                            limits = [min(limits[0], min(x)),
                                      max(limits[1], max(x)),
                                      min(limits[2], min(y)),
                                      max(limits[3], max(y))]

Which is the piece of code that will throw a TypeError if x contains datetime.datetime objects.

Hope this helps your team to further improve the code. If you need me to write a full piece of code that throws the error when you run it let me know. If the error is surely on my part due to wrong usage just mention so and I'll find my own solution.

Thnx!

The register_cmap does not accept the lut keyword argument since 3.4.

See documentation for 3.3 for the deprecation notice.

Trivial typographical error in the readme.txt file:
