Customizable graphs for traces.
var Graph = require('trace-graph') , fs = require('fs'); // data would be from traces.get(cycle, fn) // in the "traces" module var graph = new Graph(data); // graph.barWidth(1); // graph.barSpacing(.5); // graph.barTip(1); // graph.max(graph.mean() + 100); // graph.max(3000); graph.barAlpha(.4); graph.scale(1, .12); graph.label('Image Uploads'); graph.color('request', '#b1daec'); graph.color('resize', '#8fcdec'); graph.color('save', '#4cb4ec'); graph.color('s3', '#1a9dec'); graph.draw(); fs.writeFileSync('out.png', graph.canvas.toBuffer()); console.log('saved out.png');
Initialize a new graph with the given
Clip the graph at a maximum of
ms. For example if a few traces
2000ms, and most are around
100ms you'll likely want to
150 or so to have a better view.
Scale the graph on the
y axis. For example if you have several hundred
thousand traces, representing them each as a single pixel on the x-axis will be
too large, you may want to try
.scale(.2, 1). Like-wise if the y-axis reaches
durations of several seconds, this equates to several thousands of pixels by default
unless a y-axis scale is applied such as
Set bar "tip" to
Set bar "width" to
Set bar "spacing" to
Set bar alpha to
color for probe
Draw the graph.
