- BaseXYPlot: enthought.chaco.base_xy_plot.BaseXYPlot
Attributes
- color
The color of the line.
color = black_color_trait
- line_style
The line dash style.
line_style = LineStyle
- line_width
The thickness of the line.
line_width = Float(1.0)
- metadata_name
The name of the key in self.metadata that holds the selection mask
metadata_name = Str('selections')
- render_style
The rendering style of the line plot.
- connectedpoints
- "normal" style (default); each point is connected to subsequent and prior points by line segments
- hold
- each point is represented by a line segment parallel to the abscissa (index axis) and spanning the length between the point and its subsequent point.
- connectedhold
- like "hold" style, but line segments are drawn at each point of the plot to connect the hold lines of the prior point and the current point. Also called a "right angle plot".
render_style = Enum('connectedpoints', 'hold', 'connectedhold')
- selected_color
The color to use to highlight the line when selected.
selected_color = ColorTrait('lightyellow') - selected_line_style
The style of the selected line.
selected_line_style = LineStyle('solid')
- traits_view
Traits UI View for customizing the plot.
traits_view = View(Item('color', style = 'custom'), 'line_width', 'line_style', buttons = [ 'OK', 'Cancel' ])

Methods
- __getstate__(self)
- get_screen_points(self)
- hittest(self, screen_pt, threshold = 7.0)
Tests whether the given screen point is within threshold pixels of any data points on the line. If so, then it returns the (x,y) value of a data point near the screen point. If not, then it returns None.
Note: This only checks data points and not the actual line segments connecting them.
- interpolate(self, index_value)
Returns the value of the plot at the given index value in screen space. Raises an IndexError when index_value exceeds the bounds of indexes on the value.
