Surface graph has issue with small time ranges

Hello,

I've had an issue for quite a while and thought it would be good to raise here. It's an issue with graphs that are over a small amount of time. I've attempted to make a demonstration but the screenshot below will show my issue more clearly.

Take a look at the following:
A) https://jsfiddle.net/Lv4qpoyu/3/
B) https://jsfiddle.net/5au0xepd/1/

In A) you can see some random data over 50 minutes. In B) you can see random data over 50 seconds. A) works perfectly well, nice little graph. B) looks like an utter mess and is near impossible to use.

So that brings us to C), the screenshots (the first taken a few months ago, the second today) below that shows my real dataset. In a 2D heatmap it works fine but in a 3D surface graph it shows the data correctly but with the axis completely messed up. Sometimes it looks worse than others, but all the time there is a continuation of the date (y) axis. Sometimes it requires you to zoom out to see, but it is always there in the distance. This makes it unusable to me if I want to put it in front of users.

When I've looked online for help I found someone else having the exact same issue but they were using the python version of the library with a scatter3d.

This seems to be a bug opposed to an issue in my code. I have autorange set to false, the range of data is correct (["2018-09-06 20:48:32", "2018-09-06 20:55:57"] for second screenshot) and is using moment dates. I have double checked it on the latest version too and no change. Does anyone have any idea what is causing this issue?

Cheers
Shane

Commencez par les reproductions JSFiddle liées et comparez le comportement du graphe de surface pour des plages de 50 minutes et de 50 secondes. Suivez la gestion de l’axe des dates et de autorange pour les petites plages temporelles, puis vérifiez que le graphe de surface reste utilisable sans prolongement parasite de l’axe des dates.
