Reusable Charting Library Based On SVG And D3.js – vector-charts

Description:

vector-charts is a lightweight, reusable, customizable, scalable (SVG) charting library based on D3.js.

Chart Types:

  • Line Chart
  • Area Chart
  • Line + Area Chart
  • Stacked Area Chart
  • Line + Stacked Area Chart
  • Pie Chart
  • Donut Chart
  • Bar Chart
  • Multi series Bar Chart

Basic Usage:

1. Download the package and load the necessary JavaScript & CSS files:

<!-- Stylesheet -->
<link rel="stylesheet" href="vector-charts.css" />

<!-- All In One -->
<script src="vector-charts.min.js"></script>  
         
<!-- Import Modules On Demand -->       
<script src="vector-charts-lazy.min.js"></script>

<!-- Or A Specific Module You Find Under The DIST folder -->       
<script src="barseries.min.js"></script>
...

2. Insert an empty SVG element into the chart container.

<div id="container" class="chart">
  <svg>
  </svg>
</div>

3. The JavaScript to render a line chart.

Vector Chart Line

const opts = {
  chart: {
      heading: "Timeseries",
      chartIndex: 2,
      height: 270,
      margin: {
          top: 40,
          right: 15,
          bottom: 50,
          left: 15
      },
      chartResize: true,
      chartType: "timeseries",
      isTouchScreen: !!(navigator.maxTouchPoints || ("ontouchstart" in window))
  },
  data: jdata,
  yAxis: {
      left: {
          unit: 'Count',
          tickNumber: 5,
          formadt(d) { // Format all series belong to this Y Axis
              return d
          }
      }
  },
  zoom: {
      visible: true,
      onXZoom() {
          console.log('im x zoom')
      }
  },
  series: {
      line: [{
          name: 'Series-A',
          color: "#386CB0",
          lineWidth: '2px',
          plotAxis: ["left", "bottom"]
      }, {
          name: 'Series-B',
          color: "#666699",
          lineWidth: '2px',
          plotAxis: ["left", "bottom"]
      }, {
          name: 'Series-C',
          color: "#368669",
          lineWidth: '2px',
          plotAxis: ["left", "bottom"]
      }]
  }
};
vc.plotChart('#container', opts).then(chart => myChart = chart)

4. Render the time series data as an area chart.

      right: 15,
      bottom: 50,
      left: 15
    },
    chartResize: true,
    chartType: "timeseries"
  },
  data: jdata,
  xAxis: {
    bottom: {
      label: 'Time',
      tickNumber: 5,
    }
  },
  yAxis: {
    left: {
      unit: 'Count',
      tickNumber: 5,
      label: 'Count',
      format(d) { // Format all series belong to this Y Axis
        return d
      }
    }
  },
  zoom: {
    visible: true,
    onXZoom(st, et) {
      console.log('im x zoom', st, et)
    }
  },
  series: {
    stack: [{
      name: 'StackGroup', // Name of stack
      plotAxis: ["left", "bottom"], // Define its axis dependency for all below defined series
      stackOrderMembers: [{
        name: 'Series-A',
        color: "#990506",
      }]
    }]
  }
};
