Hello,
I am trying to make an app to plot the signals received from a
microcontroller. The main point is to be able to plot the signal from the
different channels. I created different checkboxes in order to be able to
choose from which channel I want to plot the data.
I have this code for one checkbox and it works:
def plot_channels(self,ch):
self.view = pg.GraphicsView()
self.view.show()
if ch.text() == "Channel 0":
if ch.isChecked() == True:
self.dataPlot_0 = np.sin(np.linspace(0, 5 *np.pi , 2000))
self.graph_0 = pg.PlotItem()
self.graph_0.plot(self.dataPlot_0)
self.lay = pg.GraphicsLayout()
self.lay.addItem(self.graph_0)
self.view.setCentralItem(self.lay)
#self.view.showMaximized()
However, when I create a second checkbox related to another channel and
also check it another window appears with the second signal and replace the
first one.
I want to have only one window when the different plots appear as soon I
check the respective checkbox.
Can someone help me to figure it out?
Thank you for the time and help.
Regards,
RR
