I'm testing pyqtgraph for possible use in a project. I'm primarily
interested in how it facilitates flowcharts that can transmit data from
node to node. I'm using PyCharm and Python 3.4 on a Windows PC. When I run
the Flowchart.py in the examples directory, the results window opens with
the top fine and the botton plot empty. Clicking on "Flowchart" opens the
flowchart. Clicking on the nodes produces the key errors below. What might
cause the gaussian filter not to produce results? What might cause these
errors? Additionally, is there anything that might complicate the design of
a custom node that receives rows from a SQLITE database (or a previous
node) using QtSql and PySide, executes a select query, and passes the
resulting rows to the output?
C:\Python34\python.exe
C:/Python34/Lib/site-packages/pyqtgraph/examples/Flowchart.py
Using PySide (default graphics system)
