Pretty graphs for traces
Customizable graphs for traces.
var Graph = require'trace-graph'fs = require'fs';// data would be from traces.get(cycle, fn)// in the "traces" modulevar graph = data;// graph.barWidth(1);// graph.barSpacing(.5);// graph.barTip(1);// graph.max(graph.mean() + 100);// graph.max(3000);graphbarAlpha4;graphscale1 12;graphlabel'Image Uploads';graphcolor'request' '#b1daec';graphcolor'resize' '#8fcdec';graphcolor'save' '#4cb4ec';graphcolor's3' '#1a9dec';graphdraw;fswriteFileSync'out.png' graphcanvastoBuffer;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.
