Thank you Daniel for the answer. Yes, I figured that's how things calculated as well, but is there any practical way to change the chartArea.height, when I'm flipping the number of bars from my bar chart between 10 and 100 using the javascript listed in http://jsfiddle.net/12r0ztoa/5/?
I'm guessing, to use `<div id="chart_div"></div>` (without the height style), then somehow magically change the chartArea.height on the fly when changing the filter, but I'm actually without a clue how to do it as I am not a javascript developer. If it is even slightly possible, I can convert http://jsfiddle.net/12r0ztoa/5/ into a bar chart, just to give people an easy start for showing me how to do.
