Line Charts when updated to Swift 4 dates at bottom automatically removed automatically.

I have upgraded my code to swift 4 and when I checked graph it automatically removed date from it. I have tried lot of different things but it didn't appear after that. Not able to upload images here some git issue sorry for that.

Start by reproducing the reported Swift 4 line-chart behavior and inspect how dates are configured and rendered at the bottom of the chart. The issue provides no file or test entry point; done means the date labels remain visible after the chart is updated.
