func PercentChangeToXoX ¶
PercentChangeToXoX converts a 1.0 == 100% based `float64` to a XoX percentage `float64`.
func PrettyTicks ¶
PrettyTicks returns a slice of integers that start lower and end higher than the supplied range. This is intended to be used for chart axis.
func PrettyTicksPercent ¶
func Round ¶
Round returns the nearest integer, rounding half away from zero. This function is available natively in Go 1.10
Special cases are:
Round(±0) = ±0 Round(±Inf) = ±Inf Round(NaN) = NaN
This function is from the following gist by gdm85: https://gist.github.com/gdm85/44f648cc97bb3bf847f21c87e9d19b2d
