Custom DataTable

[czibula istvan]

Hi,

I'm working on a GWT project and I want to include some charts into
the existing application.
I already have the necessary data on the client (browser) side in
some custom objects and i need an efficient way to serve this data as
input for the chart.
Constructing a DataTable would create o copy of the data, so I was
thinking that maybe there is a way to create a bridge between my data
format and the data format required by the charts.
Can I avoid the data duplication?

Regards,
Istvan

AFAIK, the charts require a visualization dataTable object (or a dataView object derived from a dataTable) to function.  It is possible to read the data out of a dataTable object, though, so if you are dead set against having duplicate data, you could use a dataTable object as the primary source.

Well, you can keep your custom objects in your existing application
and duplicate only the information that you want to render in a chart
and you minimize dupplicates.

Also, if charts are the only type of data output in your application,
consider saving the information in your client with DataTable
structures.
