Bar chart is not grouped in comparison with only 2 experiments

Describe the bug

When comparing bar charts of multiple experiments, the bars are not grouped properly. This only happens when 2 experiments are selected:

With 3 experiments the bars are grouped:

To reproduce

I use the following code to log bar charts:

values=[1, 2, 3, 4]
names=['a', 'b', 'c', 'd']
Logger.current_logger().report_histogram('metric', 'test', values=values, xlabels=names)

Note, this also happens if I use report_plotly with a plotly figure.

Expected behaviour

The bar charts for the same metric are grouped together.
