pygmt.Figure.text

Figure.text(textfiles=None, x=None, y=None, position=None, text=None, angle=None, font=None, justify=None, **kwargs)

Plot or typeset text strings of variable size, font type, and orientation.

Must provide at least one of the following combinations as input:

  • textfiles

  • x/y, and text

  • position and text

Full parameter list at https://docs.generic-mapping-tools.org/latest/text.html

Aliases:

  • B = frame

  • C = clearance

  • D = offset

  • G = fill

  • J = projection

  • N = no_clip

  • R = region

  • V = verbose

  • W = pen

  • X = xshift

  • Y = yshift

  • c = panel

  • f = coltypes

  • p = perspective

  • t = transparency

Parameters

  • textfiles (str or list) – A text data file name, or a list of filenames containing 1 or more records with (x, y[, angle, font, justify], text).

  • x/y (float or 1d arrays) – The x and y coordinates, or an array of x and y coordinates to plot the text

  • position (str) –

    Sets reference point on the map for the text by using x,y coordinates extracted from region instead of providing them through x/y. Specify with a two letter (order independent) code, chosen from:

    • Horizontal: L(eft), C(entre), R(ight)

    • Vertical: T(op), M(iddle), B(ottom)

    For example, position="TL" plots the text at the Upper Left corner of the map.

  • text (str or 1d array) – The text string, or an array of strings to plot on the figure

  • angle (int, float, str or bool) – Set the angle measured in degrees counter-clockwise from horizontal (e.g. 30 sets the text at 30 degrees). If no angle is explicitly given (i.e. angle=True) then the input to textfiles must have this as a column.

  • font (str or bool) – Set the font specification with format size,font,color where size is text size in points, font is the font to use, and color sets the font color. For example, font="12p,Helvetica-Bold,red" selects a 12p, red, Helvetica-Bold font. If no font info is explicitly given (i.e. font=True), then the input to textfiles must have this information in one of its columns.

  • justify (str or bool) – Set the alignment which refers to the part of the text string that will be mapped onto the (x,y) point. Choose a 2 character combination of L, C, R (for left, center, or right) and T, M, B for top, middle, or bottom. E.g., BL for lower left. If no justification is explicitly given (i.e. justify=True), then the input to textfiles must have this as a column.

  • projection (str) – Required if this is the first plot command. projcode[projparams/]width. 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.

  • clearance (str) – [dx/dy][+to|O|c|C]. Adjust the clearance between the text and the surrounding box [Default is 15% of the font size]. Only used if pen or fill are specified. Append the unit you want (c for cm, i for inch, or p for point; if not given we consult PROJ_LENGTH_UNIT) or % for a percentage of the font size. Optionally, use modifier +t to set the shape of the textbox when using fill and/or pen. Append lower case o to get a straight rectangle [Default is o]. Append upper case O to get a rounded rectangle. In paragraph mode (paragraph) you can also append lower case c to get a concave rectangle or append upper case C to get a convex rectangle.

  • fill (str) – Sets the shade or color used for filling the text box [Default is no fill].

  • offset (str) – [j|J]dx[/dy][+v[pen]]. Offsets the text from the projected (x,y) point by dx,dy [0/0]. If dy is not specified then it is set equal to dx. Use j to offset the text away from the point instead (i.e., the text justification will determine the direction of the shift). Using J will shorten diagonal offsets at corners by sqrt(2). Optionally, append +v which will draw a line from the original point to the shifted point; append a pen to change the attributes for this line.

  • pen (str) – Sets the pen used to draw a rectangle around the text string (see clearance) [Default is width = default, color = black, style = solid].

  • no_clip (bool) – Do NOT clip text at map boundaries [Default is will clip].

  • verbose (bool or str) –

    Select verbosity level [Default is w], which modulates the messages written to stderr. Choose among 7 levels of verbosity:

    • q - Quiet, not even fatal error messages are produced

    • e - Error messages only

    • w - Warnings [Default]

    • t - Timings (report runtimes for time-intensive algorithms);

    • i - Informational messages (same as verbose=True)

    • c - Compatibility warnings

    • d - Debugging messages

  • xshift (str) – [a|c|f|r][xshift]. Shift plot origin in x-direction.

  • yshift (str) – [a|c|f|r][yshift]. Shift plot origin in y-direction. Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#xy-full.

  • panel (bool or int or list) – [row,col|index]. Selects a specific subplot panel. Only allowed when in subplot mode. Use panel=True to advance to the next panel in the selected order. Instead of row,col you may also give a scalar value index which depends on the order you set via autolabel when the subplot was defined. Note: row, col, and index all start at 0.

  • coltypes (str) – [i|o]colinfo. Specify data types of input and/or output columns (time or geographical data). Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#f-full.

  • perspective (list or str) – [x|y|z]azim[/elev[/zlevel]][+wlon0/lat0[/z0]][+vx0/y0]. Select perspective view and set the azimuth and elevation angle of the viewpoint. Default is [180, 90]. Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#perspective-full.

  • transparency (int or float) – Set transparency level, in [0-100] percent range. Default is 0, i.e., opaque. Only visible when PDF or raster format output is selected. Only the PNG format selection adds a transparency layer in the image (for further processing).
