I am writing a datasource in java to feed data to a scatterplot from a mysql database. The data is sparse: not every column has a value for every row. I can easily plot sparse data manually in javascript or in the java GWT by only setting certain values in a DataTable. Is there a way to generate sparse data from a servlet with the Visualization- DataSource java API?
Using addCell to add an empty string to numerical data throws an error. Thanks, Carlos -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
