I am not allowed to share screenshots and jsfiddle is blocked here. Let me try to explain better.
Assuming the following is true,
1) I have a stacked column graph
2) My x-axis is a date
3) I have data for Jan 1st, Jan 3rd, Jan 4th
When my graph is rendered it is showing me along the x-axis labels
Jan 1st, Jan 2nd, Jan 3rd, Jan 4th
I do not have any data for Jan 2nd and I dont see it being passed anywhere on my side. Additionally, if I mouse over the gap that Jan 2nd creates I dont get a tooltip, so that leans me even more towards the fact that I am not causing this.
If you guys have an email we can correspond over it, I can share SS there.
Thanks for any help
