Hello!
I have adapted my example for using 3 elements in the stack. I pasted the entire code here in the comment. But what you need to focus on is how you add on mode go.Bar object. It should have the same offset group but the base must be a list where each element is the sum of the two previous bars at the same position. Here I use a list comprehension for this, [val1+val2 for val1, val2 in zip(data["model_1"],data["model_2"])]
data={"original":[15,23,32,10,23],"model_1":[4,8,18,6,0],"model_2":[11,18,18,0,20],"model_3":[20,10,9,6,10],"labels":["feature","question","bug","documentation","maintenance"]}fig=go.Figure(data=[go.Bar(name="Original",x=data["labels"],y=data["original"],offsetgroup=0,),go.Bar(name="Model 1",x=data["labels"],y=data["model_1"],offsetgroup=1,),go.Bar(name="Model 2",x=data["labels"],y=data["model_2"],offsetgroup=1,base=data["model_1"],),# NEW CODE
go.Bar(name="Model 3",x=data["labels"],y=data["model_3"],offsetgroup=1,base=[val1+val2forval1,val2inzip(data["model_1"],data["model_2"])],)# END NEW CODE
],layout=go.Layout(title="Issue Types - Original and Models",yaxis_title="Number of Issues"))fig.show()
Hi Let say if I have more than 2 elements to stack, how do I get about doing it ?
I having problem doing a 3 elements stack. The stacked chart does not give me the correct value.

[val1+val2 for val1, val2 in zip(data["model_1"],data["model_2"])]Hello Fredrik,
Thanks for the pointer. Did not expect that I need to use list comprehension for base that have more than 3 elements to stack.
Yeah, this cleared my doubt.
Thanks
No problem! Glad I could help 😄
