How do I reduce the gap between the Y Axis title and the Y axis?

[User (Legacy)]

Hello!

I need to reduce the gap between title of the Y axis on my chart, and the Y

axis as much as possible.  I know there are left, right, top and bottomgap

properties, but these only specify the gap from the edge to the chart.  I

need something that will allow me to reduce the gap between the Y axis title

and the graph.  As shown in the attached file

Cheers
