I have a bar chart which shows the percentages of specified names.
I wanna draw a reference line at 90 %.
I tried out Presentation> Reference> add> Expression....
but no luck..
Can anyone look into this.
Select Combo Chart and add a 0.90 line chart expression and label it 90%.
You can do the same with the refence expression: 90% as label and 0.9 as expression.
Usually it goes wrong because you forgot to set it on the secondary axis because it is a percentage xpression.
