scatter3

scatter3(cmd0::String="", arg1=[]; kwargs...)

Reads (x,y,z) triplets and plot symbols at those locations on a map. This module is a subset of plot to make it simpler to draw scatter plots. So many (fine) controlling parameters are not listed here. For a finer control, user should consult the plot module.

Parameters

• B or axes or frame
  Set map boundary frame and axes attributes. Default is to draw and annotate left, bottom and vertical axes and just draw left and top axes. More at frame

• J or proj or projection : – proj=<parameters>
  Select map projection. More at proj

• R or region or limits : – limits=(xmin, xmax, ymin, ymax, zmin, zmax) | limits=(BB=(xmin, xmax, ymin, ymax, zmin, zmax),) | ...more
  Specify the region of interest. Default limits are computed from data extents. More at limits

• G or markerfacecolor or MarkerFaceColor or mc or fill
  Select color or pattern for filling of symbols [Default is no fill]. Note that plot will search for fill and pen settings in all the segment headers (when passing a GMTdaset or file of a multi-segment dataset) and let any values thus found over-ride the command line settings (but those must be provided in the terse GMT syntax). See Setting color for extend color selection (including color map generation).

• S or symbol or marker or Marker or shape : – Default is cube with size of 7 points

  • symbol=symbol string
    A full GMT compact string.

  • symbol=(symb=..., size=..., unit=...)
    Where symb is one Symbols like :circle, size is symbol size in cm, unless unit is specified i.e. :points

  In alternative to the symbol keyword, user can select the symbol name with either marker or shape and symbol size with markersize, ms or just size. The value of these keywords can be either numeric (symb meaning size in cm) or string if an unit is appended, e.g. markersize=5p. This form of symbol selection allows also to specify a variable symbol size. All it's need for this is that the keywrd's value be an array with the same number of elements as the number of data points.

• p or view or perspective : – view=(azim, elev)
  Default is viewpoint from an azimuth of 200 and elevation of 30 degrees.
  Specify the viewpoint in terms of azimuth and elevation. The azimuth is the horizontal rotation about the z-axis as measured in degrees from the positive y-axis. That is, from North. This option is not yet fully expanded. Current alternatives are:

  • view=??
    A full GMT compact string with the full set of options.

  • view=(azim,elev)
    A two elements tuple with azimuth and elevation

  • view=true
    To propagate the viewpoint used in a previous module (makes sense only in bar3!)

  More at perspective

• figname or savefig or name : – figname=name.png
  Save the figure with the figname=name.ext where ext chooses the figure image format.

Examples

A scatter of ten points plotted as black cubes of 7 points size using the default perspective of 200,30

using GMT
scatter3(rand(10,10,3), zsize=4, marker=:cube, mc=:darkgreen, show=true)
