# pygmt.Figure.contour¶

Figure.contour(x=None, y=None, z=None, data=None, **kwargs)

Contour table data by direct triangulation.

Takes a matrix, (x,y,z) 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, y, and z.

[TODO: Insert more documentation]

Aliases:

• B = frame

• C = levels

• G = label_placement

• J = projection

• L = triangular_mesh_pen

• R = region

• S = skip

• W = pen

• i = columns

• l = label

Parameters
• x/y/z (1d arrays) – Arrays of x and y coordinates and values z of the data points.

• data (str or 2d array) – Either a data file name or a 2d numpy array with the tabular data.

• projection (str) – Required if this is the first plot command. Select map projection.

• region (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) – '[m|p|x|y]' By default, geographic line segments are drawn as great circle arcs. To draw them as straight lines, use A.

• frame (str or list) – Set map boundary frame and axes attributes.

• levels (str) – Contour file or level(s)

• D (str) – Dump contour coordinates

• E (str) – Network information

• label_placement (str) – Placement of labels

• I (bool) – Color the triangles using CPT

• triangular_mesh_pen (str) – Pen to draw the underlying triangulation (default none)

• N (bool) – Do not clip contours

• Q (float or str) – Do not draw contours with less than cut number of points. '[cut[unit]][+z]'

• skip (bool or str) – Skip input points outside region '[p|t]'

• pen (str) – Set pen attributes for lines or the outline of symbols.

• label (str) – Add a legend entry for the contour being plotted. Normally, the annotated contour is selected for the legend. You can select the regular contour instead, or both of them, by considering the label to be of the format [annotcontlabel][/contlabel]. If either label contains a slash (/) character then use | as the separator for the two labels instead.
