Struggling with a multi bar chart and wanting to add an s curve - here is the source data - not sure if this will work, but wanted to show the accumulated curve over top of the bar chart for ABC? It might be that I have my data structured incorrectly to get the result I want? The chart looked good with the data for A, B, C but I do not know how to now add the 3 remaining rows of data to create the s curve over top. Any help or advice would be much appreciated - thank in advance.
