Is it possible to produce a popup menu when using wx.lib.plot instead
of a traditional menu? I'd like to be able to right click and select
from there.
Thanks

You should be able to bind a handler for EVT_CONTEXT_MENU and pop up your own menu from there.

I'm almost there but I've hit another snag. I am trying to implement
the zoom and drag functionality on my plot like the example in the
wx.lib.plot and I can't get the check functionality working and so it
seems that when I do try to drag, it seems like the zoom functionality
is enabled and so it all goes badly wrong. I've put a sample of code
below, any pointers greatly appreciated.
import wx
import wx.lib.plot
class Plot(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
self.data = [(1,2), (2,3), (3,5), (4,6), (5,8), (6,8),
(10,10)]
markers = wx.lib.plot.PolyMarker(self.data, legend='',
colour='pink', marker='triangle_down', size=1)
gc = wx.lib.plot.PlotGraphics([markers], 'Scatter Graph', 'X
Axis', 'Y Axis')
client.Draw(gc, xAxis=(0,15), yAxis=(0,15))
client.Bind(wx.EVT_CONTEXT_MENU, self.OnContextMenu)
def OnContextMenu(self, event):
# only do this part the first time so the events are only
bound once
if not hasattr(self, "popupID01"):
self.popupID01 = wx.NewId()
self.popupID02 = wx.NewId()
client.Bind(wx.EVT_MENU, self.OnEnableZoom,
id=self.popupID01)
client.Bind(wx.EVT_MENU, self.OnEnableDrag,
id=self.popupID02)
# make a menu
self.pMenu = wx.Menu()
# add some items
self.pMenu.Append(self.popupID01, 'Enable &Zoom', 'Enable
Mouse Zoom', kind=wx.ITEM_CHECK)
self.pMenu.Append(self.popupID02, 'Enable &Drag', 'Activates
dragging mode', kind=wx.ITEM_CHECK)
# Popup the menu. If an item is selected then its handler
# will be called before PopupMenu returns.
client.PopupMenu(self.pMenu)
self.pMenu.Destroy()
def OnShowPopup(self, event):
pos = event.GetPosition()
pos = client.ScreenToClient(pos)
client.PopupMenu(self.pMenu, pos)
def OnEnableZoom(self, event):
client.SetEnableZoom(event.IsChecked())
self.pMenu.Check(self.popupID01, not event.IsChecked())
def OnEnableDrag(self, event):
client.SetEnableDrag(event.IsChecked())
self.pMenu.Check(self.popupID02, not event.IsChecked())
class MyForm(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, wx.ID_ANY, "Plotting Ex",
size=(500,500))
# Add a panel so it looks correct on all platforms
self.panel = wx.Panel(self, wx.ID_ANY)
global client
client = wx.lib.plot.PlotCanvas(self.panel)
btn6 = wx.Button(self.panel, 1, 'scatter')
btn6.Bind(wx.EVT_BUTTON, self.OnScatter)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(btn6, 0, wx.ALL|wx.CENTER, 5)
sizer.Add(client, 1, wx.EXPAND | wx.ALL, 5)
self.panel.SetSizer(sizer)
def OnScatter(self, event):
myPlot = Plot(self.panel)
# Run the program
if __name__ == "__main__":
app = wx.PySimpleApp()
frame = MyForm().Show()
app.MainLoop()

Since you need to create the popup menu each time you use it you will need to do the Check() of the checkable items to show the current state before you do the popup.

Finally figured it out. Got the checks working and also fixed the drag
issue that was fixed by the following line:
client.Draw(gc, xAxis=(0,15), yAxis=(0,15)
becomes:
client.Draw(gc, xAxis=(0.0,15.0), yAxis=(0.0,15.0))
but it took a lot of finding.
