Only can get the last row in my bar chart

[Herman]

Hi, everyone,

 

I have a bar chart need to display a set of datas from a database. I'm using the "select clause". unfortunatly i can only display the last row of data in the bar chart. however, those data can be displayed correctly in a normal band. anyone can advise me how to get around it?

 

Thanks heaps.

I'm guessing you have the key expression in the barchart data set. If all the values have the same key each row will overwrite the previous one and only the last row will be plotted.

 

Take a good look at the sample bar chart in the demos that come with JasperReports for examples of what the various expressions should be.
