The component has been migrated to LitElement and uses TypeScript now. This migration introduced two breaking changes.
The Polymer-specific selection-changed event commonly used for 2-way bindings has been removed.
There were previously two events for observing chart selection changes: google-chart-select and the Polymer-generated selection-changed.
For consistency with other events (e.g. google-chart-ready), we keep only google-chart-select.
Polymer components using this feature must be updated to explicitly name the selection event (details).
In the example below, note the addition of ::google-chart-select.
- <google-chart selection="{{chartSelection}}"></google-chart>
+ <google-chart selection="{{chartSelection::google-chart-select}}"></google-chart>LitElement components using the selection-changed event must be updated in a similar fashion:
- <google-chart .selection="${chartSelection}" @selection-changed="${reactToChartSelection}"></google-chart>
+ <google-chart .selection="${chartSelection}" @google-chart-select="${reactToChartSelection}"></google-chart>Its functionality can be imported from the loader.js module:
import {dataTable, load} from '@google-web-components/google-chart/loader.js';or you may instead choose to use google.visualization.ChartWrapper directly (example).
Instructions for running the tests and demo locally:
