    ng2-nvd3

    Build Status NPM Version

    Angular2 component for nvd3. It has similar technique as angular-nvd3 for angular 1, but designed for angular 2 and without extra features (like extended mode) you won't need.

    Demos

    Online demos:

    1. web page
    2. plnkr

    Install

    npm install ng2-nvd3
    

    it requires angular2, d3 and nvd3 as dependencies. Tested with the current @angular version ^2.0.0-rc.4.

    Basic usage

    Simple bar chart

    Note: d3 and nvd3 should be also included in your project bundle.

    Simple discrete bar chart:

    import {Component, OnInit} from '@angular/core';
    import {nvD3} from 'ng2-nvd3'
    declare let d3: any;
    
    @Component({
      selector: 'main',
      directives: [nvD3],
      template: `
        <div>
          <nvd3 [options]="options" [data]="data"></nvd3>
        </div>
      `
    })
    
    export class Main implements OnInit{
      options;
      data;
      ngOnInit(){
        this.options = {
          chart: {
            type: 'discreteBarChart',
            height: 450,
            margin : {
              top: 20,
              right: 20,
              bottom: 50,
              left: 55
            },
            x: function(d){return d.label;},
            y: function(d){return d.value;},
            showValues: true,
            valueFormat: function(d){
              return d3.format(',.4f')(d);
            },
            duration: 500,
            xAxis: {
              axisLabel: 'X Axis'
            },
            yAxis: {
              axisLabel: 'Y Axis',
              axisLabelDistance: -10
            }
          }
        }
        this.data = [
          {
            key: "Cumulative Return",
            values: [
              {
                "label" : "A" ,
                "value" : -29.765957771107
              } ,
              {
                "label" : "B" ,
                "value" : 0
              } ,
              {
                "label" : "C" ,
                "value" : 32.807804682612
              } ,
              {
                "label" : "D" ,
                "value" : 196.45946739256
              } ,
              {
                "label" : "E" ,
                "value" : 0.19434030906893
              } ,
              {
                "label" : "F" ,
                "value" : -98.079782601442
              } ,
              {
                "label" : "G" ,
                "value" : -13.925743130903
              } ,
              {
                "label" : "H" ,
                "value" : -5.1387322875705
              }
            ]
          }
        ];
      }
    
    }

    Usage directive api

    No need to use api as in angular 1 case. We can get access to directive instance from parent component via @ViewChild:

    import {Component, OnInit, AfterViewInit, ViewChild} from '@angular/core';
    import {nvD3} from 'ng2-nvd3';
    
    @Component({
      selector: 'main',
      directives: [nvD3],
      template: `<div><nvd3 [options]="options" [data]="data"></nvd3></div>`
    })
    export class Main {
      options;
      data;
    
      @ViewChild(nvD3)
      nvD3: nvD3;
    
      ngOnInit(){
        this.options = {...};
        this.data = [...];
      }
    
      ngAfterViewInit() {
        // this.nvD3 - directive instance
        // for example, to update the chart
        this.nvD3.chart.update()
      } 
    }
