[jCharts-users] RE: FW: Problem generating Bar Charts from Database

[Campano, T. <Tro...@Li...>]

I was able to find out my problem, however this is my new problem.
My Y-Axis is incrementing by 100. My highest data element only goes to
24.
So I tried:

		try
		{
			dataAxisProperties.setUserDefinedScale( 0, 50 );
		}
		catch( PropertyException propertyException )
		{
			propertyException.printStackTrace();
		}

But It still goes 0, 100, 200, 300, 400.
When I remove the code, it still does the same thing.

Any Ideas?

Thank you, once again.

I don't think your code is correct.  Are you sure you want
'amount_of_rows' for each dimension of
the data array?
