The graph size didn't work correctly if there are multiple dcc.graph in one page

Only the size of the last dcc.graph is as expected. Can anybody explain why?

My hunch is that your are trying to put figures of height 600px into Div containers with defined height 300px. I suppose this will trigger some overflow which is not handled well… (This is just a guess :slightly_smiling_face:)

Yes,Blaceus is right. I should sync all the height in go.layout. Thanks for Blaceus’s suggestion.
