Types

type Axis 

type Axis interface {
	root.Named

	XMin() float64
	XMax() float64
	NBins() int
	XBins() []float64
	BinCenter(int) float64
	BinLowEdge(int) float64
	BinWidth(int) float64
}

Axis describes a ROOT TAxis.

type Graph 

type Graph interface {
	root.Named

	Len() int
	XY(i int) (float64, float64)
}

Graph describes a ROOT TGraph

Example 
package main

import (
	"fmt"
	"log"

	"go-hep.org/x/hep/groot"
	"go-hep.org/x/hep/groot/rhist"
)

func main() {
	f, err := groot.Open("../testdata/graphs.root")
	if err != nil {
		log.Fatal(err)
	}
	defer f.Close()

	obj, err := f.Get("tg")
	if err != nil {
		log.Fatal(err)
	}

	g := obj.(rhist.Graph)
	fmt.Printf("name:  %q\n", g.Name())
	fmt.Printf("title: %q\n", g.Title())
	fmt.Printf("#pts:  %d\n", g.Len())
