Golang ComposeDot Examples

Example #1

File: report.go Project: linearregression/pprof

// printDOT prints an annotated callgraph in DOT format.
func printDOT(w io.Writer, rpt *Report) error {
	g, origCount, droppedNodes, droppedEdges := rpt.newTrimmedGraph()
	rpt.selectOutputUnit(g)
	labels := reportLabels(rpt, g, origCount, droppedNodes, droppedEdges, true)

	c := &graph.DotConfig{
		Title:       rpt.options.Title,
		Labels:      labels,
		FormatValue: rpt.formatValue,
		Total:       rpt.total,
	}
	graph.ComposeDot(w, g, &graph.DotAttributes{}, c)
	return nil
}

Example #2
