scatter-plot-d3 v1.0.2

scatter-plot-d3

Package for Easily Generating Scatter Plots & Line Graphs using D3

Basic Usage:

• npm install -S scatter-plot-d3

• import in code

  • import 'd3Scatter from 'scatter-plot-d3'

• Add canvas element to html page (d3Canvas is the default id expected)

  • <div id='#d3Canvas' />

• Call addScatter

  • const data_example = [{country: 'USA', gdp: 20.8, population: 331}, {country: 'China', gdp: 14.9, population: 1406}, {country: 'Japan', gdp: 4.9, population: 126}, {country: 'Germany', gdp: 3.8, population: 83}, {country: 'France', gdp: 2.6, population: 67}]
  • d3Scatter.addScatter({data: data, xCol: 'gdp', yCol: 'population'})

Options:

• specify canvas size (defaults to 900 x 600)

  • (automatically adjusts size to fit canvas)
  • d3Scatter({data: data, xCol: 'population', yCol: 'gdp', canvasHeight: 500, canvasWidth: 800})

• add line / curve

  • d3Scatter({data: data, line: true})
  • d3Scatter({data: data, curve: true})

• specify axis labels

  • (automatically adjusts size to fit canvas)
  • d3Scatter({data: data, xCol: 'population', yCol: 'gdp', xaxis: 'population (in Millions)', yaxis: 'GDP ($USD in millions)'})

• specify scale

  • (overrides auto-scaling that fits plot to canvas size)
  • d3Scatter({data: data, scale: 0.2})

• check default settings

  • var defaults = d3Scatter.checkDefaults()
  • this allows you to check values like 'scale', 'maxValue' etc. if you have customized the canvas size and/or scaling
  • var defaults = d3Scatter.checkDefaults({data: data, scale: 10, canvasHeight: 500, canvasWidth: 800})

• embed data table in page

  • add empty element in html
  • <div#embedDataHere />
    • d3Scatter.addScatter({data: data, embedData: "embedDataHere"})
