Newbie question: Which graph to create

Hi,

I'm trying to redo an application and it displays a graph like this.

1) Should I use histogram for this?

2) What is the bins in the HistogramDataset().addSeries(key, values, bins)?

Thanks.

Desmond

The answer depends on the data you have. Certainly an XYBarChart could be used...

Thanks David.

The data:
The x-axis displays the weight and the y-axis is the intensity. It isn't time based, can the XY Bar Chart still be used?

Also need to know what the bin is?

Thanks.

The bin is the bar in an histogram chart, so, in HistogramDataset().addSeries(key, values, bins) you must provide how many bins (how many bars) will appear in your chart.

By the way I have a question: I'm using the HistogramDataset to build a hitogram graph and I want to display it on a web page (jsp) with cewolf but I can't find any correspondece. For cewol I have:
<cewolf:chart type="verticalBar"
and
<cewolf:chart type="verticalxybar"

but it does'nt work.Anyone knows what type to use with HistogramDataset?

thanks in advance,
