Displaying the generated chart within the grid provided popup window will suit most needs. However you may wish to display the chart in a different location. For example, your application may already have popup windows and you wish to use the same library for consistency.
To provide an alternative container for popup windows use the grid callback
createChartContainer(chartRef). The interface is as follows:
The callback is called each time the user elects to create a chart via the grid UI. The callback
is provided with a
ChartRef containing the following:
chartElement: The chart DOM element, which the application is responsible for placing into the DOM.
destroyChart: The application is responsible for calling destroyChart() when the chart is no longer needed.
The example below demonstrates the
createChartContainer() callback. The example does not
use an alternative popup window, instead it just places the charts into the DOM below the grid. This
crude approach is on purpose to minimise the complexity of the example and focus on just the callback
and the interactions of the grid.
From the example, the following can be noted:
- Select a range of numbers (medal columns) and create a chart from the context menu.
The chart appears below the grid rather than in a popup window. This is because the
Each chart is displayed alongside a 'Destroy' button. The logic behind the destroy
destroyChart()to destroy the chart instance.
