I've created my own vertical bar graph in the Dashboard section. All is going well, except that I can't figure out how to force the side bar measurement (the Y axis gradations) to be whole numbers. My chart is counting contacts, and so it's pretty silly to have the sidebar list the increments as 0, 1.2, 2.7, 3.1, and so on.

The XML for the Y axis says:
<yData min="0" max="'.$yMax.'" length="'.$yMax.'" kDelim="," defaultAltText="Rollover each bar for details."/>

I suspect that I need to do something clever with 'length', but I'm not sure. Setting it to be the same as $yMax works as long as the numbers are small, but not when they get big. Is there another attribute I should be using instead, or should I employ some clever form of rounding?

Thanks
