Installation
npm install @stdlib/plot
Usage
var plot = require( '@stdlib/plot' );
plot
Plot API.
var x = [ 1, 2, 3 ];
var y = [ 1, 0, 1 ];
var plt = plot( [ x ], [ y ] );
Examples
var randn = require( '@stdlib/random/base/box-muller' );
var Float64Array = require( '@stdlib/array/float64' );
var now = require( '@stdlib/time/now' );
var plot = require( '@stdlib/plot' );
var t;
var x;
var y;
var i;
// Create some data...
t = now() * 1000;
x = new Float64Array( 100 );
y = new Float64Array( x.length );
for ( i = 0; i < x.length; i++ ) {
x[ i ] = t + (i*360000);
y[ i ] = 50.0 + (10.0*randn());
}
// Create a new plot:
var plt = plot( [x], [y], {
'width': 600,
'height': 480,
'xScale': 'time',
'xTickFormat': '%H:%M',
'renderFormat': 'html'
});
// Render as a virtual DOM tree:
var vtree = plt.render( 'vdom' );
console.log( JSON.stringify( vtree ) );
// Render as HTML:
var html = plt.render();
console.log( html );
// Listen for 'render' events (e.g., when triggered due to changes in state):
plt.on( 'render', onRender );
setTimeout( update, 1000 );
function update() {
plt.width = 720;
}
function onRender( html ) {
console.log( html );
}
