Hi,
I want to visualise a live data-stream by a number of plots (3d,
line drawings, scatter plots etc). I've been using the simpler
animation techniques (using gobject.idle_add and wx.EVT_IDLE to
redraw updates).
Some plots have static backgrounds that may benefit from the blit
techniques and I have been trying to get this approach to work in
GTKAgg and WXAgg. GTKAgg on linux seems to be coming along fine.
WXAgg on linux or macos, I'm not getting very far with.
So can anyone help with a few questions?
- can the native macos backend be used for animation? What's the
equivalent of gobject.idle_add or gobject.timeout_add? Anything
special needed for the blitting approach to work?
- What needs to be done to get WXAgg blitting? I have code like this:
...
matplotlib.use('WXAgg')
...
def update():
...
# restore, blit etc
wx.WakeUpIdle()
...
wx.EVT_IDLE(wx.GetApp(), update)
...
On Linux this draws the first screen and pauses. If I move the mouse
around I see the updates. As soon as I stop, so do the updates. What
am I missing? (BTW I get the same behaviour from animation_blit_wx.py
from the examples page). This is 1.0.1 on Linux, although I'm still
using 0.99.1 as well.
thanks for any help,
cheers, chris
