Using a graph on two tabs.

[Ed Schneider]

I realize that a widget can appear in only one place. In the past I used matplotlib to create a fig and then the code below to put one instance of it on one tab (Plot) and another instance, a different name, on another tab (Gallery). The first replaces whatever had been on the tab before. The second goes to the end of whatever is on the tab. I now want to do the same thing except using pyqtgraph rather than matplotlib. Is there a way to do that? Just substituting a new_fig for fig gets an attribute error. Here's the original code:
def plot_to_gui(self, fig):

	# Add the plot to the Plot tab (replace the current plot)
	canvas_plot = FigureCanvas(fig)
	width, height = (
		int(fig.get_size_inches()[0] * fig.dpi),
		int(fig.get_size_inches()[1] * fig.dpi))
	canvas_plot.setFixedSize(width, height)
	canvas_plot.draw()
	self.tab_plot_scroll_area.setWidget(canvas_plot)
	# #

	# Add the plot to the Gallery tab (append to existing plots)
	canvas_gallery = FigureCanvas(fig)
	canvas_gallery.setFixedSize(width, height)
	canvas_gallery.draw()
	self.tab_gallery_layout.addWidget(canvas_gallery)

	# Add a spacer at the end to push plots to the top
	spacer = QSpacerItem(20, 40, QSizePolicy.Minimum, QSizePolicy.Expanding)
	self.tab_gallery_layout.addItem(spacer)

	plt.close(fig)
