Plot function properties (from Matplotlib) __ function

Matplotlib.pyplot. Plot (*args, **kwargs)

Plot lines and/or markers to the Axes. Args is a variable length argument, allowing to multiple x, y pairs with a optional format string. For example, each of the following is legal:

Plot (x, y)         # Plot x and y using default line style and color
plot (x, y, ' Bo ')   # Plot x and y using blue circle Markers
Plot (y)            # Plot y using X as index array 0..n-1
plot (y, ' r+ ')      # ditto, but with red plusses

If x and/or Y is 2-dimensional, then the corresponding columns would be plotted.

An arbitrary number of x, Y, FMT groups can is specified, as in:

A.plot (x1, y1, ' g^ ', x2, y2, ' G ')

Return value are a list of lines that were added.

By default, the assigned a different color specified by a ' color cycle '. To change this behavior, you can edit the Axes.color_cycle rcparam. Alternatively, can use Set_default_color_cycle ().

The following format string characters are accepted to control the line style or marker:

character	Description
'-'	Solid line Style
'--'	Dashed line Style
'-.'	Dash-dot Line Style
':'	Dotted line Style
'.'	Point marker
','	Pixel marker
' O '	Circle Marker
' V '	Triangle_down Marker
'^'	TRIANGLE_UP Marker
' < '	Triangle_left Marker
' > '	Triangle_right Marker
' 1 '	Tri_down Marker
' 2 '	TRI_UP Marker
' 3 '	Tri_left Marker
' 4 '	Tri_right Marker
' s '	Square Marker
' P '	Pentagon marker
'*'	Star Marker
' H '	Hexagon1 Marker
H	Hexagon2 Marker
'+'	Plus marker
' X '	X marker
D	Diamond Marker
' d '	Thin_diamond Marker
'|'	VLine Marker
'_'	Hline Marker

The following color abbreviations are supported:

character	Color
' B '	Blue
' G '	Green
' R '	Red
C	Cyan
' m '	Magenta
' Y '	Yellow
K	Black
' W '	White

In addition, your can specify colors in many weird and wonderful ways, including full names (' green '), Hex strings (' #00800 0 '), RGB or RGBA tuples ((0,1,0,1)) or grayscale intensities as a string (' 0.8 '). Of these, the string specifications can is used in place of a FMT group, but the tuple forms can is used only as Kwargs.

Line styles and colors are combined into a single format string, as in ' Bo ' for blue circles.

The Kwargs can is used to set line properties (any property that is has a set_* method). You can use this to set a line label (for Auto Legends), LineWidth, anitialising, marker face color, etc. This is example:

Plot ([1,2,3], [1,2,3], ' go-', label= ' line 1 ', linewidth=2)
plot ([1,2,3], [1,4,9], ' rs ',  label= ' Line 2 ')
Axis ([0, 4, 0, ten])
legend ()

If you do multiple lines with one plot command, the Kwargs apply to all those lines, e.g.:

Plot (x1, y1, x2, y2, Antialised=false)

Neither line would be antialiased.

You don't need to use format strings, which are just abbreviations. All of the line properties can is controlled by keyword arguments. For example, your can set the color, marker, LineStyle, and Markercolor with:

Plot (x, y, color= ' green ', linestyle= ' dashed ', marker= ' o ',
     markerfacecolor= ' Blue ', markersize=12).
