#85 setSerieDrawable doesn't work

[John Schattel]

I'm using PHP 4.3.2 and the sample graph "Combo" shows bar charts for both "this year" and "last year" but the script is only supposed to show a bar chart for "this year" by using the setSerieDrawable() function. Similarly, there should only be a spline chart for "last year" but instead both servies are shown as a spline chart. Bottom line: reguardless of the whether you use "TRUE" or "FALSE", all data series get plotted.
