How to show desired number of setTickLabelsVisible false in line chart javafx - javafx

Question

I am trying to build a time series line chart for stock market data. I am getting the input dynamically, and its been plotted on the line chart.
All I want is to plot every tick data on the graph but want to show only desired number of tick labels.
Ex: Say I started to build the graph on 10 AM, and i am plotting on 3 sec, so after 4 hours, i.e 1 PM, i want every tick to be plotted but the the label on Xaxis should be of my choice, say only 4 tick labels (10AM,11AM,12AM,1PM).
Kindly see the desired graph:
Thanks a lot in advance. :)
