I'm trying to plot two data ranges on the same Y-axis, but cannot for the life of me figure out how to add a data set to a secondary X-axis. See attached pictures and example file.

I want the "available ice cream" plotted on the secondary X-axis and primary Y-axis, and "available dollars" plotted on the primary X-axis and primary Y-axis. When the Range of X-values for the "available ice cream" data set is set to the proper range (B2:B18 - "Ice cream"), it just plots it on the primary X-axis (A2:A18 - "Dollars"). See image below. I want it to plot against the range of values in B2:B18, i.e. 27 - 75. This is a scatter graph.

Any help would be greatly appreciated. I can't find any options in the Format Data Series or Chart Type dialogue boxes to plot on the secondary X-axis, only a secondary Y-axis, which is not enabled.

Running LibO v6.0.6.2, Windows x64. See attached example sheet. C:\fakepath\secondary x-axis range example.ods

Please forgive me but I don't understand what you are trying to do or why. You want to plot "available ice cream" as both x and y, and "available dollars" as both x and y?? So you are plotting available ice cream versus available dollars, and available dollars versus available ice cream? How does dollars (column A) differ from available dollars (E) as a percentage? Graphs usually show the relationship between a dependent variable (y) and an independent variable (x).

Those are just dummy names - sorry if it's confusing. Trying to keep possibly confidential information confidential. Basically, I want to see the second set ("available ice cream") plotted on the secondary x-axis, and the first set ("available dollars") plotted on the primary x-axis, for aesthetics. I agree that it's kind of confusing. Dependent (x) for set 1 is "dollars", independent (y) is "available dollars"; dependent (x) for set 2 is "ice cream", independent (y) is "available ice cream".

I could be wrong, but I don't think it is possible to have a secondary x-axis in Calc. The purpose of a graph is usually to compare one or several different variables (plotted as y) with a single, common, independent variable (plotted as x). A graph with more than one y-axis and more than one x-axis will be ambiguous. The meaning of your data might be more clearly represented by having two separate graphs.
