svg-plot.js

svg-plot.js is a simple library to programatically create svg plots from csv formatted data. This is designed for regression testing where a visual component of data is desired.

Install:

nmp install svg-plot

Usage:

var svg_plot = require('svg-plot.js');
svg_plot.plot(csvData,options)

Column CSV Example:

var fs = require('fs');
var svg_plot = require('../svg-plot.js')
var csvString = fs.readFileSync('testThermal.csv').toString();

svg_plot.plot(csvString,{
    fileName:'myPlot',
    timeKey:'Time'
});

// Generates myPlot.svg

Usage Output: examples/myPlot.svg

Note, this will render on github but may not on npm's registery. See examples/myPlot.svg for reference.

Pivot(row) CSV Example:

This example demonstrates a pivot style csv file where the key is contained within the row itself. This example also demonstrates some more optional arguments.

var fs = require('fs');
var svg_plot = require('../svg-plot.js')
var csvString = fs.readFileSync('testpivotThermal.csv').toString();

svg_plot.plot(csvString,{
    fileName:'mypivotPlot',
    timeKey:'Time',
    pivotCSV:true,
    pivotKey:'Point',
    pivotValue:'Value',
    y2List:['heat1'],
    includeList:['activeSp','temperature','heat1'],
    title: 'Heating Example',
    y2Range:[0,3]
});

Usage Output: examples/myPivotPlot.svg
