Staggered Axis Labels

I have a vision Chart here with 4 subplots. Version 8.1.25

I am looking for a way to stagger the labels to the left so that one is higher than the next and they won't be overlapping anymore.

I am not working with a lot of height here and using subplot titles above each subplot and I also thought to use a label angle but those options won't work for me either.

Another alternative might be if I could somehow insert a html break to put the units on a line to the right of the plot title.

If anyone has any suggestions, let me know please. Thanks!

This is as close as I can get to figuring out how to do a line break but System doesn't exist.

def configureChart(self, chart):
#Set Mode to x-trace, 0=Zoom
self.setMode(4)

from org.jfree.chart.axis import NumberAxis
from java.lang import System
from java.awt import Font
from java.awt import Color

titles = ["FLOW TEST","CRACK TEST","LEAK TEST","CAGE LEAK TEST"]

for index, plot in enumerate(chart.getPlot().getSubplots()):
	labelAxis = NumberAxis(titles[index] + System.getProperty("line.separator") + ' units')
	labelAxis.setLabelFont(Font("Tahoma", Font.PLAIN, 10))
	plot.setRangeAxis(0, labelAxis)

Update:
I could not get the stagger effect or the multiple line effect to work.
I ended up finding an alternative solution by moving the pen title somewhere else and keeping the units on the y axis.
