The library depends on the following packages (so they could be required if you don't have):

npm install moment --save
npm install loadh --save
npm install d3 --save
npm install @types/d3 --save-dev

Provide information about installed library module in the AppModule of your application:

import {NgxPolarChartModule} from '@vanavara/ngx-polar-chart';

@NgModule({
  declarations: [],
  imports: [NgxPolarChartModule],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

Use chart components in the application

Use component for group polar chart in your template:

<ngx-polar-chart-group [chartData]="sampleDataSet"></ngx-polar-chart-group>

Use component for stack polar chart in your template:

<ngx-polar-chart-stack [chartData]="sampleDataSet"></ngx-polar-chart-stack>

[chartSettings] overview

<ngx-polar-chart-group [chartSettings]="settingsSample"></ngx-polar-chart-group>

<ngx-polar-chart-stack [chartSettings]="settingsSample"></ngx-polar-chart-stack>

Chart settings is a type in the library:

export interface NgxPolarChartSettings {
  width?: number;
  height?: number;
  fontSettings?: NgxPolarChartFontSettings;
  showToolTip?: boolean;
  barsSettings?: NgxPolarChartBarSettings;
  labelSettings?: NgxPolarChartLabelSettings;
  tickSettings?: NgxPolarChartTickSettings;
  showLegend?: boolean;
  locale?: string;
}

More info can be found here.

If chart settings is null then default settings will be applied. By default it means:

• Always show tool tip with value of certain item in the group
• Always highlight average, maximum and minimum values on the chart
• Always auto generate colors in hex format for each group
• In case of NgxDateGroup (we work with dates and display by day of month) always show weekends of certain month

All parameters are optional. And if chart settings is not null then nullable parameters will be overriden by default values

Displaying data set on the chart in case of Date type

Just use NgxGroupBy enum in NgxDateGroup.

export interface NgxDateGroup {
  groups: NgxGroups<Date>[];
  groupBy?: NgxGroupBy;
}

Localization of chart in case of Date type

In the chart settings ([chartSettings]) the parameter will have to be specified:

export interface NgxPolarChartSettings {
  locale?: string;
}
