Custom graph in excel, x value is always 100% and y is a less than or greater than, showing that percent

Question

I have made a big macro generateing a graph to dynamic data. However, one of my graphs will show actual hours vs estimated. I am using a stacked 100% but the porblem is est vs act can only be possible if est is < actual. I would like to set actual at 100% then have the second data series, estimated, to be either below or aboe that 100% to show 80% or 120% etc.

Thanks so much :)!

Perhaps a stacked bar is not the best type of chart for this problem.

Why not just use a simple column chart plotting the deviation (+/-), like this:

The research nerd in me suggests using stacked bar/column only for ordinal data type :) eg, categories like "< 1 week", "1-2 weeks", "3+ weeks", etc.

Alternatively used a simple stacked bar/column (ie, NOT the stacked 100%), which should allow you to display values like 120%.
