Hi Diego,
With pg.plot (
http://www.pyqtgraph.org/documentation/functions.html#pyqtgraph.plot) you
create a new PlotWindow every time you start this function, but you need to
create them just one time and then fill with setData (
http://www.pyqtgraph.org/documentation/graphicsItems/plotcurveitem.html#pyqtgraph.PlotCurveItem.setData)
function. So, you are overloading (probably) ViewBox with lots of a new
plots.
You should do something like this:
// initalize the PlotWindows
self.pg_plot_one_1 = self.pg_plot_one.plot()
self.pg_plot_one_2 = self.pg_plot_one.plot()
then in a loop:
self.pg_plot_one.setRange(xRange=range(self.n)[d:]) // maybe this line
not need in a loop. look at
http://www.pyqtgraph.org/documentation/graphicsItems/viewbox.html#pyqtgraph.ViewBox.setRange
self.pg_plot_one_1.setData(self.y1[d:], pen=(1, 3), antialias=True)
self.pg_plot_one_2.setData(self.y2[d:], pen=(2, 3), antialias=True)
Of course, it is the best that you make combination you need.
Good luck,
Vasilije
