Bases: Artist
A line - the line can have both a solid linestyle connecting all the vertices, and a marker at each vertex. Additionally, the drawing of the solid line is influenced by the drawstyle, e.g., one can create "stepped" lines in various styles.
Create a Line2D instance with x and y data in sequences of xdata, ydata.
Additional keyword arguments are Line2D properties:
See set_linestyle() for a description of the line styles, set_marker() for a description of the markers, and set_drawstyle() for a description of the draw styles.
Test whether mouseevent occurred on the line.
An event is deemed to have occurred "on" the line if it is less than self.pickradius (default: 5 points) away from it. Use get_pickradius or set_pickradius to get or set the pick radius.
MouseEvent
Whether any values are within the radius.
A dictionary {'ind': pointlist}, where pointlist is a list of points of the line that are within the pickradius around the event position.

Get the artist's bounding box in display space, ignoring clipping.
The bounding box's width and height are non-negative.
Subclasses should override for inclusion in the bounding box "tight" calculation. Default is to return an empty bounding box at 0, 0.
Warning
The extent can change due to any changes in the transform stack, such as changing the Axes limits, the figure size, the canvas used (as is done when saving a figure), or the DPI.
Relying on a once-retrieved window extent can lead to unexpected behavior in various cases such as interactive figures being resized or moved to a screen with different dpi, or figures that look fine on screen render incorrectly when saved to file.
To get accurate results you may need to manually call savefig or draw_without_rendering to have Matplotlib compute the rendered size.
RendererBase, optional
Renderer used to draw the figure (i.e. fig.canvas.get_renderer()).
Return the xdata.
If orig is True, return the original data, else the processed data.

Set multiple properties at once.
Supported properties are
Alias for set_antialiased.
Set whether to use antialiased rendering.
Alias for set_color.
Set the color of the line.
How to draw the end caps if the line is is_dashed.
The default capstyle is rcParams["lines.dash_capstyle"] (default: <CapStyle.butt: 'butt'>).
CapStyle or {'butt', 'projecting', 'round'}
How to join segments of the line if it is_dashed.
The default joinstyle is rcParams["lines.dash_joinstyle"] (default: <JoinStyle.round: 'round'>).
JoinStyle or {'miter', 'round', 'bevel'}
Set the dash sequence.
The dash sequence is a sequence of floats of even length describing the length of dashes and spaces in points.
For example, (5, 2, 1, 2) describes a sequence of 5 point and 1 point dashes separated by 2 point spaces.
See also set_gapcolor, which allows those spaces to be filled with a color.
If seq is empty or (None, None), the linestyle will be set to solid.
Set the x and y data.
Set the drawstyle of the plot.
The drawstyle determines how the points are connected.
For 'default', the points are connected with straight lines.
The steps variants connect the points with step-like lines, i.e. horizontal lines with vertical steps. They differ in the location of the step:
'steps-pre': The step is at the beginning of the line segment, i.e. the line will be at the y-value of point to the right.
'steps-mid': The step is halfway between the points.
'steps-post: The step is at the end of the line segment, i.e. the line will be at the y-value of the point to the left.
'steps' is equal to 'steps-pre' and is maintained for backward-compatibility.
For examples see Step Demo.
Alias for set_drawstyle.
Set the marker fill style.
Possible values:
'full': Fill the whole marker with the markerfacecolor.
'left', 'right', 'bottom', 'top': Fill the marker half at the given side with the markerfacecolor. The other half of the marker is filled with markerfacecoloralt.
'none': No filling.
For examples see Marker fill styles.
Set a color to fill the gaps in the dashed line style.
Note
Striped lines are created by drawing two interleaved dashed lines. There can be overlaps between those two, which may result in artifacts when using transparency.
This functionality is experimental and may change.
The color with which to fill the gaps. If None, the gaps are unfilled.
Set the linestyle of the line.

Set the markevery property to subsample the plot when using markers.
e.g., if every=5, every 5-th marker will be plotted.
Which markers to plot.
every=None: every point will be plotted.
every=N: every N-th marker will be plotted starting with marker 0.
every=(start, N): every N-th marker, starting at index start, will be plotted.
every=slice(start, end, N): every N-th marker, starting at index start, up to but not including index end, will be plotted.
every=[i, j, m, ...]: only markers at the given indices will be plotted.
every=[True, False, True, ...]: only positions that are True will be plotted. The list must have the same length as the data points.
every=0.1, (i.e. a float): markers will be spaced at approximately equal visual distances along the line; the distance along the line between markers is determined by multiplying the display-coordinate distance of the Axes bounding-box diagonal by the value of every.
every=(0.5, 0.1) (i.e. a length-2 tuple of float): similar to every=0.1 but the first marker will be offset along the line by 0.5 multiplied by the display-coordinate-diagonal-distance along the line.
For examples see Markevery Demo.
Notes
Setting markevery will still only draw markers at actual data points. While the float argument form aims for uniform visual spacing, it has to coerce from the ideal spacing to the nearest available data point. Depending on the number and distribution of data points, the result may still not look evenly spaced.
When using a start offset to specify the first marker, the offset will be from the first data point which may be different from the first the visible data point if the plot is zoomed in.
If zooming in on a plot when using float arguments then the actual data points that have markers will change because the distance between markers is always determined from the display-coordinates axes-bounding-box-diagonal regardless of the actual axes data limits.
