A version of Vaadin Charts that uses less memory with large datasets.

This version doesn't keep references to the data shown in the charts, but just pushes that directly to the browser. This saves a lot of memory if you are drawing charts with large or huge data.

Note that to use this add-on, you'll also need a valid license to Vaadin Charts. Only the extension part comes with Apache 2.

Sample code

        // Instantiate LightChart instead of Chart 
        Chart chart = new LightChart(ChartType.COLUMN);
        // Use the exact same API as with Chart 
        chart.getConfiguration().addSeries(createLargeSeries());
        add(chart);
