Issue with Sunburst Highcharts when using unique color schemes and custom tooltips

Hi there,

1] I'm facing an issue with implementing a custom color scheme in highcharts. Despite using a colors array, the sequence of colors applied is random and sometimes repeats.

2] Additionally, I have encountered an error while trying to create a custom tool-tip.

I have prepared a stackblitz demo:

https://stackblitz.com/edit/angular-ivy-mz3dhi?file=src%2Fapp%2Fapp.component.html,src%2Fapp%2Fapp.component.ts,src%2Fapp%2Fapp.module.ts,package.json

Your assistance would be greatly appreciated!

Answer №1

Appreciate you sharing your code - it looks like you'll need to sort your information based on the hierarchy level. For example:


data: [
            {
              id: '0.0',
              parent: ' ',
              name: 'Main Parent',
            },
            {
              id: '1.3',
              parent: '0.0',
              name: 'John',
            },
            {
              id: '1.2',
              parent: '0.0',
              name: 'Jessica',
            },
            {
              id: '1.1',
              parent: '0.0',
              name: 'James',
            },
            {
              id: '2.1',
              parent: '1.1',
              name: 'Subsection A',
            },
            ...
            ...
            ...
      ]

Utilizing Highcharts within Angular may require extending types at times. Check out this informative guide on extending Highcharts in TypeScript for more details.

interface CustomPointLabelObject extends Highcharts.PointLabelObject {
}


tooltip: {
  formatter: function( this: CustomPointLabelObject) {
    return 'custom tooltip'
  }
},
