Simple, I am using BIRT designer and not using any API, I have three data sets each retrieve a particular variable say temperature, The temp-south, temp-north and temp-west.
How do I show all them on a single meter chart. Basically how do I access three different data sets and assign dia1, dial2 and dial 3 to three different data sets respectively?
Using basic report designer in eclipse. Any help??? Rolling Eyes

Have you tried using joint dataSets to merge your data into a single dataSet? Then, using this final dataSet in your chart?

Add interactivity, scheduling, sharing, live Excel export, and JS integration to your BIRT app with the new, free BIRT server, BIRT iHub F-Type.

I see. Is this the only way to achieve this?

You'll have to create a single dataSet, somehow. You could use a joint dataSet, rewrite your query to only have a single dataSet, use a scripted dataSet to take the values from your other 3 dataSets to make a single dataSet, or you could take the values from the 3 dataSets, create a chart dataSet, in your chart script and set the chart to use this data, in the beforeGeneration script.
