Redesign the way the x-axis works for wxLineChart

Open xleclercq opened this issue 8 years ago • 2 comments

At the moment it only works if there are as many labels as data points. It should be possible to have data points at other positions than the tick marks. A good example of this is for time series where there can be many points between marks,

I've been investigating the code of wxLineChart (and related classes) a bit (while trying to implement #108 ), and it seems a lot of refactoring will be needed to implement the redesign of x-axis (unless I overlooked something to make it simpler). AFAIK the x-axis supports arbitrary (non-ordered) non-numeric marks (a kind of labels), so it will be tricky to implement interpolation of points when the x-values are not ordered. Anyway I would pick this issue up, since it is likely it will be needed for my application. And it would be great if you shared your ideas/hints how to implement it :)

Yes a lot of refactoring will be needed for this. I need to check where I left on this but if memory serves I was going to define distinct types of x-axis with a common interface so that any kind of thing is possible there. But this needs a lot of refactoring to have a clean interface for the axes.
