Basics of Plotting a Bar chart!

[nittu02]

Hey,

 

Am a very new user to i-reports and i would like some clarification on some points! any help would be really appreciated.

 

I have created a pie chart which gives a plot between the name of the users and the number of cases associated to them. So the wedge size varies according to the number of cases/spcific user.The key expression was $F{user_name} and value expression was $V{SUM_case_number_COUNT_1}

 

How do i create a bar chart to reflect the same situation?

that is, on the X-axis i want the name of the users and on the Y- axis i want the number of cases assigned to them.

 

What should be the series, X, and Y expressions?? plz help.

The Category expression would be the username, the Value expression would be the number of calls.

 

You only have one dataset, so the Series expression can be any static value (eg. new java.lang.Integer(1) or "My Series")

Hey thanks a lot... now there is just one more doubt.. where do i put this bar chart? i tried putting it in the "title" band but there was no data. then, there was pageheader and then a custom band i created called username. when i put the chart into details, it is printing fine, but it repeats in every page. is there any way to print it only once??? size=400]http://www.jasperforge.org/components/com_joomlaboard/uploaded/images/screenshot.JPG

The placement of any chart will depend on what you want to display.

 

 

Generally speaking a chart will show summary information, so you would put it in the LastPageFooter band or Summary band
