Please help with this graph

[cho]

I am trying to plot a graph using iReports1.2.5 with names on Xaxis and Age on Yaxis as a line graph.

I wrote the query for that and the data is returning properly. But the graph is not showing any data. I entered $F{age} for series expression and category expression as $F{name} and value expression as $F{total_enters}.

Can someone help me to identiy what iam missig here. This is very urgent for me.

 

Thanks

Hi,

 

Where did you placed the chart? What evaluationTime have you used for it?

Could you post the JRXML here?

 

You could recheck the supplied examples in the /demo/samples/charts folder of our project distribution.

 

I hope this helps.

The series expression gives a way to collect a bunch of data into a set, which is useful when you want to plot multiple things on a single graph, such as age and height. In this case you set the series to be $F{age} so it thinks you have a bunch of different data series.

 

Set the seriesExpression to "Age", the category expression to "$F{name}" and the value to "$F{age}". That should help.
