svg-timegraph
Easy to use Node.JS/Browserify library to render time graph into SVG.
Example
How to use it?
$ npm install svg-timegraph
Generate a time-graph using:
var SVGTimeGraph = require('svg-timegraph');
var output = SVGTimeGraph(
// List of data series
[
{
title: "Visits",
color: "#1d7fb3",
points: [
{
value: 200,
date: new Date(2015, 06, 10)
},
{
value: 100,
date: new Date(2015, 06, 11)
},
{
value: 230,
date: new Date(2015, 06, 12)
},
{
value: 600,
date: new Date(2015, 06, 13)
}
]
}
],
//
{
// Size of the SVG
width: 800,
height: 300,
// Minimum value for the Y axe
// if null, it will be extracted from data
minValue: null,
// Radius of point
pointRadius: 4,
// Stroke width
lineWidth: 1,
// Color for axe
axeColor: '#eee',
// Text styling
textColor: '#aaa',
textFontSize: 10,
textFontFamily: 'helvetica'
}
);
Use the autoFill
option when a time serie is incomplete:
var SVGTimeGraph = require('svg-timegraph');
var output = SVGTimeGraph(
// List of data series
[
{
title: "Visits",
color: "#1d7fb3",
points: [
{
value: 200,
date: new Date(2015, 06, 10)
},
{
value: 100,
date: new Date(2015, 06, 11)
},
{
value: 600,
date: new Date(2015, 06, 13)
}
]
}
],
//
{
// Activate the auto-fill
autoFill: true,
// Value to use for missing data
// Default is 0
autoFillValue: 0,
// Interval of the time serie in ms
// Points that are not in the interval will be ignored
autoFillInterval: 1000 * 60 * 60 * 24,
// By default, autoFill completes the serie from the minimum date
// to the maximum date of the series
// Override this behavior by setting the two following options
// Default to minimum date of the series
autoFillStartTime: new Date(2015, 06, 07),
// Default to maximum date of the series
autoFillEndTime: new Date(2015, 06, 14)
// Other options...
}
);
