pygmt.Figure.plot¶

Figure.
plot
(x=None, y=None, data=None, sizes=None, direction=None, **kwargs)¶ Plot lines, polygons, and symbols on maps.
Used to be psxy.
Takes a matrix, (x,y) pairs, or a file name as input and plots lines, polygons, or symbols at those locations on a map.
Must provide either data or x and y.
If providing data through x and y, color (G) can be a 1d array that will be mapped to a colormap.
If a symbol is selected and no symbol size given, then psxy will interpret the third column of the input data as symbol size. Symbols whose size is <= 0 are skipped. If no symbols are specified then the symbol code (see S below) must be present as last column in the input. If S is not used, a line connecting the data points will be drawn instead. To explicitly close polygons, use L. Select a fill with G. If G is set, W will control whether the polygon outline is drawn or not. If a symbol is selected, G and W determines the fill and outline/no outline, respectively.

 Parameters
y (x,) – The x and y coordinates, or arrays of x and y coordinates of the data points
data (str or 2d array) – Either a data file name or a 2d numpy array with the tabular data. Use option columns (i) to choose which columns are x, y, color, and size, respectively.
sizes (1d array) – The sizes of the data points in units specified in style (S). Only valid if using x and y.
direction (list of two 1d arrays) – If plotting vectors (using
style='V'
orstyle='v'
), then should be a list of two 1d arrays with the vector directions. These can be angle and length, azimuth and length, or x and y components, depending on the style options chosen.J (str) – Required if this is the first plot command. Select map projection.
R (str or list) – Required if this is the first plot command.
'xmin/xmax/ymin/ymax[+r][+uunit]'
. Specify the region of interest.A (bool or str) –
'[mpxy]'
By default, geographic line segments are drawn as great circle arcs. To draw them as straight lines, use A.B (str or list) – Set map boundary frame and axes attributes.
C (str) – File name of a CPT file or
C='color1,color2[,color3,...]'
to build a linear continuous CPT from those colors automatically.D (str) –
'dx/dy'
: Offset the plot symbol or line locations by the given amounts dx/dy.E (bool or str) –
'[xyXY][+a][+clf][+n][+wcap][+ppen]'
. Draw symmetrical error bars.G (str) – Select color or pattern for filling of symbols or polygons. Default is no fill.
S (str) – Plot symbols (including vectors, pie slices, fronts, decorated or quoted lines).
W (str) – Set pen attributes for lines or the outline of symbols.
l (str) – Add a legend entry for the symbol or line being plotted.
