Angular Fails to Identify Chart.js Plugin as an Options Attribute

Encountering issues with using the 'dragData' plugin in Chart.js 2.9.3 within an Angular environment: https://github.com/chrispahm/chartjs-plugin-dragdata

After importing the plugin: chartjs-plugin-dragdata, I added dragdata to the options as shown below:

this.comboChart1 = new Chart("bar1", {
  type: "bar",

  options: {

    dragData: true,

    onDragStart: function (e) {
    },

    onDrag: function (e, datasetIndex, index, value) {
      // console.log(datasetIndex, index, value)
    },

    onDragEnd: function (e, datasetIndex, index, value) {
      // console.log(datasetIndex, index, value)
    },
    //Set Formatting

  },

Unfortunately, 'dragData' is not being recognized as a valid chart option. The error message received is as follows:

Type '{ plugins: { zoom: { pan: { enabled: true; mode: string; sensitivity: number; }; zoom: { enabled: true; mode: string; sensitivity: number; }; }; }; responsive: true; title: { display: true; text: any; position: "top"; fontSize: number; }; ... 6 more ...; onDragEnd: (e: any, datasetIndex: any, index: any, value: any)...' is not assignable to type 'ChartOptions'.
  Object literal may only specify known properties, and 'dragData' does not exist in type 'ChartOptions'.ts(2322)
index.d.ts(278, 9): The expected type comes from property 'options' which is declared here on type 'ChartConfiguration'

Receiving the following error:
index.d.ts(278, 9): The expected type comes from property 'options' which is declared here on type 'ChartConfiguration'

Update: Successfully resolved the issue by taking two steps: 1. Downgrading the plugin to version 1.1.13 for compatibility with Chart.js 2.9.3. 2. Extending the chartOptions interface. After adding the missing properties: dragdata, ondragstart, ondrag, ondragend, the plugin started functioning correctly with the provided options code.

Answer №1

When defining plugin options for Chart.js, make sure to specify them within the plugins section of the options object like shown below:

new Chart(ctx, {
  type: 'line',
  data: data,
  options: {
    plugins: {
      dragData: {
        onDragStart: function () {},
        onDragEnd: function () {},
      }
    }
  }
});

Another crucial point to note is that if you are using Chart.js version 2, you may need to downgrade your drag plugin as the latest version is compatible with V3. The recommended drag version for Chart.js V2 is 1.1.13. You can switch to this version by updating it directly in your package.json file and then running npm install once again.
