Query: How can I display a Chart of Subreport Data [message #1797601] Fri, 02 November 2018 14:16

I am developing a BIRT report that contains a nested sub-report. I would like to display a chart (bar chart or pie chart) of all of the sub-report data. But I cannot point the chart at any source of data (table, list, data set etc) that has all the data that I need. If I point it at the data set that I use to drive the sub-report, I just get the data from one iteration of the sub-report, not from all the iterations.

The outer data set of my report is based on a data set that returns all the equipment that has energy monitoring power meters.

The inner data set retrieves (one at a time), the consumption values from each of power meters over a specific time period (for instance a week), and calculates the increase in the value.

The attachment is the report data that is generated.

What I would like is some way of charting the six consumption figures, for instance into two pie charts, one for Active Power and one for Reactive Power. Each pie chart would have three slices, with a size proportional to the consumption value.

Can anyone help?
