Struct astrup::mark::Mark

pub struct Mark { /* fields omitted */ }

Mark

This struct is used to determine ticks and gridlines (if they are visible). It sits in the background, and is used when building the canvas and the axis. Grids and ticks are ``visible versions'' of a mark, in that they are used to visualise where a mark is located.

Methods

impl Mark

fn new(coord: Coord) -> Mark

Create and return a new mark

fn set_local(&mut self, coord: Coord)

Set local mark coordinate

fn set_global(&mut self, coord: Coord)

Set global mark coordinate

fn set_label_content(&mut self, content: &str)

Set label content

fn set_font_size(&mut self, val: f64)

Set label font size

fn set_label_offset(&mut self, hor: f64, ver: f64)

Set label offset in vertical and horisontal direction

fn set_tick_color(&mut self, color: Rgba)

fn set_tick_width(&mut self, val: f64)

fn set_tick_length(&mut self, val: f64)

Set the length of the tick, in both positive and negative extent

fn set_positive_tick_length(&mut self, val: f64)

Set the positive length of the tick

fn set_negative_tick_length(&mut self, val: f64)

Set the negative length of the tick

fn set_tick_direction(&mut self, direction: &Coord)

Set the direction of the tick. It is only the unsigned version of the direction that is used, that is, its angle. The extension of the tick is controlled by its positive_length and negative_length.

fn global_coord(&self) -> Coord

Return the global coordinate

fn global_x(&self) -> f64

Return the first element of the global coordinate

fn global_y(&self) -> f64

Return the second element of the global coordinate

fn label(&self) -> Text

Return the label

fn label_hor_offset(&self) -> f64

Return the label horisontal offset

fn label_ver_offset(&self) -> f64

Return the label vertical offset

fn scale_label_offset(&mut self, factor: f64)

Scale the vertical and horisontal label offset

fn fit(&mut self, parent_frame: &Frame)

Fit the mark to the parent frame

fn draw(&self, cr: &Context, fig_rel_height: f64, fig_rel_width: f64)

Draw ticks and labels

Trait Implementations

impl Clone for Mark

fn clone(&self) -> Mark

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mark

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
