Description: After making an x-y chart with two series I used Insert Axes and checked the box to have a secondary X axis. But then I can't tell Calc to use it. When I try to format one of the series and choose the tab Options there's an option ot "Align Data Series to Secondary Y axis", but there's nothing to make it use the secondary X axis. Steps to Reproduce: As stated in Description Actual Results: It doesn't allow me to use the secondary X axis. Expected Results: It should allow me to use the secondary X axis. Reproducible: Always User Profile Reset: No Additional Info: None
Such is not implemented and does not exist as predefined ODF-chart. So this is an enhancement request. There are some other bug reports with similar topic: bug 125753, bug 96520, bug 64160. ODF allows to use charts in application-defined namespace. So not having an predefined ODF-chart does not hinder LibreOffice to implement such feature.
Sorry, I don't understand your answer at all. I don't understand the terms you use! Why is there an option to ask for a secondary X axis? Isn't it possible to use it?
The secondary x-axis has currently no relation to the position of the data points. The primary x-axis is used to place the data points. You can use the secondary x-axis for to show the scaling in a different unit. For example, your primary x-axis is in inch and your secondary x-axis is in cm.
