Hiding Specific Axis Labels
It is occasionally necessary to only show labels for specific ticks on an Axis. By passing an array of values to the .labels( ) method, it’s possible to specify which tick labels are visible:
var bottom = new d3plus.AxisBottom()
.labels([0, 1, 3, 5, 7, 8, 9, 10])
Notice that while the labels have been modified, the ticks/gridlines still appear at default intervals. This behavior can be overridden using the .ticks( ) method, as seen in this example.
