We are currently using Charts for our project. I always get the dates on the X axis starting from 0 and ending in *MyData*+1. This being a problem since I want to display the days of a month...from 1 to....28/30/31. I tried playing with the JSON but even with "tick0" : 1 ....it won't do a thing. The charts do the same things if I display date-time on the X axis. If I'm to put a date in there and set "dtick" : 86400000.0 it will also show on the X axis the dates 31st of previous month and the 1st of the next month PS: the data will be shown correctly. But the extra data on the X axis is bothering. Anyone has a solution for this?
