Equal verifies that the two arguments are equal

X wraps a *testing.T and extends its functionality

NewSeries - series constructor

Open adds a new opening element with optional attributes.

Transform sets the current list of transforms that will be used by the next set of drawing operations. Specifying no transforms resets the transformat

Utilities

Next steps to the next value. A newly created iterator has no current value.

Assert verifies that a condition is true

New - Margaid constructor

Style Fill sets current fill style

StrokeWidth sets current stroke width

ValueTicker returns tick labels by converting floats using strconv.FormatFloat

Close closes a child SVG and returns the parent. If the current SVG is not a child, this is a noop.

Get returns the iterator current value. A newly created iterator has no current value.

Scaling scales by (xScale, yScale)

Size returns the current series value count

Translation moves by (x, y)

Axis draws tick marks and labels using the specified ticker

Stroke sets current stroke

TimeFromSeconds converts from seconds since the epoch to time.Time

Values returns an iterator to the series values

WithRange sets a fixed plotting range for a given axis

Alignment sets current text alignment

Font sets current font family and size

FontStyle sets the current font style and weight

New - Brackets constructor

Text draws text at x, y

Projects a value onto an axis using the current projection setting. The value returned is in user coordinates, [0..1] * width for the x-axis.

Marker adds start, mid and end markers to all following strokes. The specified marker has to be one of "circle" and "square". Setting the marker to th

getPlotColor picks hues and saturations around the color wheel at prime indices. Kind of works for a quick selection of plotting colors.

AggregatedBy sets the series aggregator

Attributes returns a copy of the element attributes

Close closes the current element. If there are no children (elements or text), the current element will be self-closed. Otherwise, a matching close-el

CloseAll closes all elements to get a complete, matched structure.

EncodeText applies proper xml escaping and svg line breaking at each newline in the raw text and returns a section ready for inclusion in a <text> ele

False verifies that a condition is false

Frame draws a frame around the chart area

LabeledTicker places tick marks and labels for all values of a series. The labels are provided by the labeler function.

MinX returns the series smallest x value, or 0.0 if the series is empty

Polyline adds a polyline from a list of points

Rect adds a rect defined by x, y, width and height

Render generates SVG code for the current image, and clears the canvas

SetAttribute resets an attribute to a new value

True verifies that a condition is true

addPlot adds a named plot and returns its ID

Add adds a self-closing element

Clone creates a deep copy of a map

Color sets current stroke and fill

Line draws a series using straight lines

MaxX returns the series largest x value, or 0.0 if the series is empty

Name returns the element name

Drawing Path adds a SVG style path

Smooth draws one series as a smooth curve

TimeTicker returns time valued tick labels in the specified time format. TimeTicker assumes that time is linear.

Titled sets the series title

WithAutorange sets range for an axis from the values of one or more series

WithBackgroundColor sets the chart background color as a valid SVG color attribute string. Default is transparent.

WithProjection sets the projection for a given axis

XMLEscape returns properly escaped XML equivalent of the provided string

Append adds all elements from another Brackets instance

Bar draws bars for the specified group of series.

CappedByAge caps a series by removing values older than cap in relation to the current value of the reference funcion.

CappedBySize caps a series to at most cap values.

Current returns a pointer to the currently open element, or nil if there is none.

First returns the first element of the underlying list of elements.

Last returns a pointer to the most recently added element, or nil if there is none.

Legend draws a legend for named plots. If position is set to BottomLeft, it will grow the plot size to accommodate the number of legends displayed.

MaxY returns the series largest y value, or 0.0 if the series is empty

MinY returns the series smallest y value, or 0.0 if the series is empty

New - SVG constructor

Transformations Rotation rotates by angle degrees clockwise around (x, y)

SetSize of SVG, redefining the value given during construction.

Drawing Title draws a title top center

WithInset sets the distance between the chart boundaries and the charting area.

WithPadding sets the padding inside the plotting area as a percentage [0..20] of the area width and height

Avg calculates the Y average of a list of values, reported as observed at the given time.

Child adds a sub-SVG at x, y

Delta calculates the Y difference between the first and last value in the list, reported as observed at the given time.

Nil verifies that the argument is nil
