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?

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.
