Missing certain xaxis labels

[jpmunz]

When using ticktext it appears that with certain data sets there are missing xaxis labels. In this example the xaxis label for 'Jan 1' is missing even though the marker for that data point is drawn and the label is shown on hover:

The bug only seems to occur with very specific data sets, for example if you remove or reorder one of the items from the data array then 'Jan 1' gets drawn properly.
