This section shows how the Grid API can be used to save and restore charts.
The example below demonstrates how you can save and then later restore a chart. You can make changes to the chart type, theme, data and formatting options and note how the restored chart looks the same as the chart that was saved.
- Change the chart type, theme, data and/or formatting in order to see the changes restored later.
- Click "Save chart" to persist a model of the visible chart into a local variable.
- Click "Clear chart" to destroy the existing chart.
- Click "Restore chart" to restore the previously saved chart.
A chart model that represent all the state information about the rendered charts can be obtained using
getChartModels(). These models are returned in a format that can be easily used with the other API methods to later restore the chart.
