var ( // ColorOrange is orange. ColorOrange = drawing.Color{R: 255, G: 165, B: 0, A: 255} // ColorGreen is green. ColorGreen = drawing.Color{R: 0, G: 255, B: 0, A: 255} )
Functions ¶
func ColorImageToDrawing ¶
ColorImageToDrawing converts a `color.RGBA` value to a `drawing.Color` value.
func GridLines ¶
func GridLines(values []float64, style chart.Style) []chart.GridLine
GridLines creates a `[]chart.GridLine` from a slice of `int64` and a style.
func MustParseColor ¶
MustParseColor returns a `drawing.Color` for the SVG color name. If the color name is not found, black is returned.
func ParseColor ¶
ParseColor returns a `drawing.Color` for the SVG color name. If the color name is not found, an error is returned.
func TSSToChart ¶ added in v1.7.0
func TSSToChart(data timeseries.TimeSeriesSet, opts ChartOptions) chart.Chart
TSSToChart converts a `TimeSeriesSet` to a `wcharczuk.Chart`.
func Ticks ¶
func Ticks(tickValues []float64, fn strconvutil.Float64ToString) []chart.Tick
Ticks converts a slice of `float64` to a slice of `chart.Tick`. Common formatting functions include `strconvutil.Commify` and `strconvutil.Int64Abbreviation`.
func TicksAndGridlinesTime ¶
func TicksAndGridlinesTime(interval timeutil.Interval, timeBegin, timeEnd time.Time, styleMajor, styleMinor chart.Style, timeFormat func(time.Time) string, tickInterval, gridInterval timeutil.Interval) ([]chart.Tick, []chart.GridLine)
TicksAndGridlinesTime takes a begin and end time and converts it to `[]chart.Tick` and `[]chart.GridLine.`.
func TicksInt64 ¶
func TicksInt64(tickValues []int64, fn strconvutil.Int64ToString) []chart.Tick
TicksInt64 converts a slice of `int64` to a slice of `chart.Tick`. Common formatting functions include `strconvutil.Commify` and `strconvutil.Int64Abbreviation`.
func TimeSeriesMapToContinuousSeriesMonths ¶ added in v1.7.0
func TimeSeriesMapToContinuousSeriesMonths(dsm map[string]timeseries.TimeSeries, order []string) []chart.ContinuousSeries
func TimeSeriesMapToContinuousSeriesQuarters ¶ added in v1.7.0
func TimeSeriesMapToContinuousSeriesQuarters(dsm map[string]timeseries.TimeSeries, order []string) []chart.ContinuousSeries
func TimeSeriesToContinuousSeries ¶ added in v1.7.0
func TimeSeriesToContinuousSeries(ds timeseries.TimeSeries) chart.ContinuousSeries
func TimeSeriesToContinuousSeriesQuarter ¶ added in v1.7.0
func TimeSeriesToContinuousSeriesQuarter(ds timeseries.TimeSeries) chart.ContinuousSeries
