Resizing Plot in Excel

Using the plotly app I have imported my graph into my excel file. It wont resize. The legend is overlaid over top of the graph. I tried to extend the graph using the excel scaling options but it is not working. I want it to be a long rectangle, is there code I can write to make it look like that?

Note I coded this in Python then using the excel plotly app. Fixed this problem but there appears to be a max size I can make my plot in excel
