Function AddYErrorBars

plotutil/add.go:366–381

AddYErrorBars adds YErrorBars to a plot. The variadic arguments must be of type plotter.XYer, and plotter.YErrorer. Each errorer is added to the plot the color from the Colors function corresponding to its position in the argument list. If an error occurs then none of the plotters are added to the

(plt *plot.Plot, es ...interface {
	plotter.XYer
	plotter.YErrorer
})

// If an error occurs then none of the plotters are added
// to the plot, and the error is returned.

	plotter.XYer
	plotter.YErrorer
}) error {
	var ps []plot.Plotter
	for i, e := range es {
		bars, err := plotter.NewYErrorBars(e)
		if err != nil {
			return err
		}
		bars.Color = Color(i)
		ps = append(ps, bars)
	}
