Plotting multiple Lines in a Line Chart

Posted on April 8, 2008 at 8:11am

Hi

I have to draw a chart that displays the month wise marketshare of various service providers.
The DB has a table which stores month , service provider and marketshare. I am using a line chart to display months on X axis and Marketshare on Y axis. I am able to draw a seperate Line graph for each service provider using IReports but I need help to draw one line chart for all service providers

Please see the attachmnet for the exampple chart that is to be drwan.

Thanks in advance [file name=Chart_sample.doc size=49152]

Hi,

each "line" needs its own "Category Series" (in Chart Properties - Chart Data - Details)

I need where clause in the value expression for each caregory series for examle correspondg to serviceoperator xyz , the value expression for category series corresponding to opeartor xyz should be saying 'plot marketshare for this record from DB if serviceoperator="xyz" '

Please tell me how to define this value expression. Thanks for your help

This is a completly different issue ;)

I would create a subreport with a query designed to return exactly the data I need in the chart - and then just put in the resluting fields. If needed you can pass parameters to your subreport (like your "YXZ").
