<b>Setting the vertical grid lines.</b>
<p>
Use the defaultGridLinesOn parameter to turn on the default vertical grid lines.
By default, there is one line between each bar.

<p>
You can control the start position and interval of the grid lines
by adding the start and interval numbers in the defaultGridLinesOn parameter.

<param name=defaultGridLinesOn value="true,10,20"><br>
<param name=range value=100><br>
</applet><br>
<p>
The start and interval numbers are relative to the sample axis range
which by default goes from 1 to 100. You can set the sample axis
range using the sampleAxisRange parameter, so you have easier
control over the lines.

In addition to the default vertical grid lines, you can set lines at explisit
positions in the chart by using the gridLines parameter and a comma seperated
list of relative positions.
