Eddie,
It seems like you are either setting minimum or viewportMinimum in axisX (observation from image shared) because of which first dataPoint is partially visible. Removing the same or setting it to null should work fine in your case.
If you are not setting minimum / viewportMinimum but facing this issue, kindly share JSFiddle reproducing the issue you are facing, so that we can look into the code, understand the scenario better and help you out.
