No curve with Python 3 and segfault with Python 2

[scls]

Hello,

I'm facing a problem with an example with PyQtGraph.

This example works fine with Anaconda Python (2 and 3) under Mac OS X

but this same code segfault with Python 2 and no curve is

displayed with Python 3 under Linux (Raspberry Pi Jessie)

Any idea ?

Kind regards

The refresh rate seems barely sustainable on a windows pc. Maybe should you try to slow buy 10x the re-drawing requirements ?

Hi Big Stone,

I don't think that's the problem.

There is a hint with integer on x axis (I'm using a unix timestamp)

which behave differently on OS X and Raspberry Pi

You might have a look at

https://github.com/scls19fr/numpy-buffer

git clone https://github.com/scls19fr/numpy-buffer.git

cd numpy-buffer

python setup.py install

than compare

python samples/sample_pyqtgraph_no_datetime.py

and

python samples/sample_pyqtgraph_with_datetime.py

both works fine on OS X (and maybe on Windows)

but samples/sample_pyqtgraph_with_datetime.py doesn't works

under Linux (with Raspberry Pi)

It's not a refresh rate problem here

problem appears (only on Linux) when axisItems parameter is passed to addPlot method

self.plot = self.win.addPlot(title='Timed data', axisItems={'bottom': TimeAxisItem(orientation='bottom')})

Some help will be great because ploting time series will be nice.

Kind regards
