Matplotlib can't handle more than 499 data points #380
Description
Bug from Thorvald at qdev.
Steps to reproduce
# VNA power scan:
v1.spec_mode(0)
v1.bandwidth(500)
v1.avg(5)
a = 6.61064e9;
v1.start(a-20e6)
v1.stop(a+20e6)
v1.npts(101)
loop = qc.Loop(v1.power.sweep(-45,-55,1)).each(v1.trace)
data = loop.get_data_set();
plot=qc.MatPlot(array, subplots=(1,2))
plot.add(array, subplot=2)
loop.with_bg_task(plot.update, 0.0005).run()Expected behaviour
The plot should show the data
Actual behaviour
The plot only show the data if a row has less than 499 points
