Plotting Date Values in Vaadin Charts

Flow
1

I’m trying to implement a Gantt chart like representation using Vaadin 7 Charts addon, and ran into trouble plotting DateTimes. All the documentation points towards having the X axis as a DateTime Axis, and plotting numerical values with respect to it.

What I’d like to do is plot Date ranges against each project step, and I can’t find how. I see Invient Charts had something called DateTimeSeries to serve the purpose, what is the equivalent of that in Vaadin 7 Charts? Help!

Hi,

I think this (yet to be released) example/test code will get you to right direction:
