Issue with Flowchart example

[Peter]

Hi,

I've been using pyqtgraph for a while under python 2.7 and PyQt 4 with no issues.

I've now switched to python 3.5.2 and PyQt5 and am having issues with the Flowchart examples that work ok with Python 2.7/PyQt 4.

Running Flowchart.py from the examples, it starts with no issue, and I see the unfiltered graph but the bottom graph which should be filtered is missing. Clicking Flowchart and looking at the GausianFilter.0 I get the following.

Is this an incompatibility with PyQt5/Python 3 ?

Thanks,

Peter
