horizontal material bar chart sizing / scaling

[Kenny Baugher]

I'm relatively new to the google charts area and have done a few, mostly timeline charts, which appear at least in the way to setup a vertical scroll bar if the about of items along the vertical axis does not fit in the chart area specified.   However when I'm working with a material bar chart, ( I chose this type to be able to have two separate haxis scales)   Regardless of how large or small I set the height of the chart area, the chart simply shrinks/expands along the vertical axis to fit the space.   The amount of data I plan to display with this chart will be variable, and I would like a consistent size to the text and bars.  Is there a way to set this behaviour?
