Changeing Y-axis in GD Graph

[frasernm]

Hi,

I've changed the y-axis minimum to be 95% instead of 0%, but while the bottom of the graph is 95%, the bars are still drawing from zero (ie disappearing off down the bottom of the canvas, covering the labels).

Does anyone know how to only draw the bars from y = 95?

Thanks in advance,

Fraser
