smile.plot.swing.BarPlot works with smile-plot 3.0.2 but not with 3.1.0

[appsofteng]

With smile-plot 3.0.2 it works as I understand the API description, but with smile-plot 3.1.0 it throws an exception.
I read there was a change:

BarPlot.getUpperBound() computes wrong bound. #752.

What should the code look like to work with smile-plot 3.1.0?
Thank you.

new BarPlot(new Bar(new double[][] { { 1, 1 } }, 1, Color.RED),
	new Bar(new double[][] { { 2, 2 } }, 1, Color.BLUE)).canvas().window();

smile-plot 3.0.2

smile-plot 3.1.0

Exception in thread "main" java.lang.IllegalArgumentException: Lower bound is larger than upper bound.
