NChartTimeAxis.h

`handler`	image for the slider’s handler.

Specify the image for the slider and the cap insets to stretch it. The cap insets works as the insets in a method [NSImage resizableImageWithCapInsets:]. This means, they specify the stretchable caps of the image.

- (void)setSliderImage:(NSImage *)slider capInsets:(NSEdgeInsets)capInsets

Parameters

`slider`	image for the slider.
`capInsets`	cap insets for the image.

`– setImagesForBeginNormal:beginPushed:endNormal:endPushed:playNormal:playPushed:pauseNormal:pausePushed:slider:handler:contentScale:`

Set all images used for time axis at once. This method automatically adjusts tickSize and tickOffset according to images provided.

- (void)setImagesForBeginNormal:(NSImage *)beginNormal beginPushed:(NSImage *)beginPushed endNormal:(NSImage *)endNormal endPushed:(NSImage *)endPushed playNormal:(NSImage *)playNormal playPushed:(NSImage *)playPushed pauseNormal:(NSImage *)pauseNormal pausePushed:(NSImage *)pausePushed slider:(NSImage *)slider handler:(NSImage *)handler contentScale:(double)contentScale

Parameters

`beginNormal`	image for the begin button’s normal state.
`beginPushed`	image for the begin button’s pushed state.
`endNormal`	image for the end button’s normal state.
`endPushed`	image for the end button’s pushed state.
`playNormal`	image for the play button’s normal state.
`playPushed`	image for the play button’s pushed state.
`pauseNormal`	image for the pause button’s normal state.

`currentIndex`

Current timestamp index (index of the timestamp tick where the handler stays).

@property (nonatomic, assign) NSInteger currentIndex

Declared In

`tooltip`

Tooltip that appears over the handler. This is nil by default.

@property (nonatomic, strong) NChartTimeAxisTooltip *tooltip

Declared In

`tickTitlesFont`

Font used to display timestamp titles.

@property (nonatomic, strong) NSFont *tickTitlesFont

Declared In

`tickTitlesColor`

Color used to display timestamp titles.

@property (nonatomic, strong) NSColor *tickTitlesColor

Declared In

NChartTimeAxis.h

`tickColor`

Color used to display timestamp ticks.

@property (nonatomic, strong) NSColor *tickColor

Declared In

NChartTimeAxis.h

`tickSize`

Size of ticks in pixels.

@property (nonatomic, assign) CGSize tickSize

Declared In

NChartTimeAxis.h

`tickOffset`

Offset of timestamp ticks (spacing between slider and ticks) in pixels. If positive, ticks are outside of slider, if negative, ticks may overlap the slider; so the outer border of the slider (including the slider’s handler) is assumed as zero offset.

@property (nonatomic, assign) float tickOffset

Declared In

NChartTimeAxis.h

`tickTitlesOffset`

Offset of timestamp titles (spacing between the slider and titles) in pixels.

@property (nonatomic, assign) float tickTitlesOffset

Declared In

NChartTimeAxis.h

`tickShape`

Shape of timestamp ticks.

@property (nonatomic, assign) NChartTimeAxisTickShape tickShape

Declared In

NChartTimeAxis.h

`tickTitlesLayout`

Layout of timestamp titles.

@property (nonatomic, assign) NChartTimeAxisLabelsLayout tickTitlesLayout

Declared In

NChartTimeAxis.h

`tickTitlesPosition`

Position of timestamp titles.

@property (nonatomic, assign) NChartTimeAxisLabelsPosition tickTitlesPosition

Declared In

NChartTimeAxis.h

`minTickSpacing`

Minimal spacing between neighbor ticks in pixels (the tick is the center place of the timestamp title, a kind of milestone on the axis). According to this value some timestamps can be hidden, if there are too many of them.

@property (nonatomic, assign) float minTickSpacing

Declared In

NChartTimeAxis.h

`margin`

Margin of the time axis.

@property (nonatomic, assign) NChartMargin margin

Declared In

NChartTimeAxis.h

`autohideTooltip`

Flag indicating whether the tooltip should be hidden automatically when the user interactions end (YES) or not (NO).

@property (nonatomic, assign) BOOL autohideTooltip

Declared In

NChartTimeAxis.h

`animationTime`

Time that takes to play the whole time axis in seconds.

@property (nonatomic, assign) float animationTime

Declared In

NChartTimeAxis.h

`padding`

Padding of the time axis.

@property (nonatomic, assign) NChartMargin padding

Declared In

NChartTimeAxis.h

`frame`

Frame of the time axis in the view’s coordinate system.

@property (nonatomic, readonly) CGRect frame

Discussion

The frame is a rect fully enclosing the entire time axis with its ticks, labels and control buttons, but not its tooltip. This rect is calculated during updateData call when the chat lays out its elements.
