Figure 15.3: Errorbar plot. Typing either sombrero or peaks at the Octave prompt should display a three dimensional plot. useful reference

The optional return value h provides a handle to the patch object. http://octave.sourceforge.net/octave/function/errorbar.html
The contour, contourf and contourc functions produce two-dimensional contour plots from three-dimensional data. The following options affect the direction of increasing values on the axes. "ij" Reverse y-axis, so lower values are nearer the top. "xy" Restore y-axis, so higher values are nearer the Many different combinations of arguments are possible. The filename and options can be given in any order. Function File: orient (orientation) Set the default print orientation.
Use e to modify properties of a specific errorbar object after it is created. Use MarkerEdgeColor and MarkerFaceColor to specify the marker outline and interior colors, respectively. marker ‘+’crosshair ‘o’circle ‘*’star ‘.’point ‘x’cross ‘s’square ‘d’diamond ‘^’upward-facing triangle ‘v’downward-facing triangle ‘>’right-facing triangle ‘<’left-facing triangle ‘p’pentagram ‘h’hexagram color ‘k’blacK ‘r’Red ‘g’Green ‘b’Blue ‘m’Magenta ‘c’Cyan ‘w’White ";displayname;" Here "displayname" is the Octave Plot Legend He can be reached at [email protected]
The argument limits should be a 2, 4, or 6 element vector. Octave Plot Error Bars Legend entries may be specified as individual character string arguments, a character array, or a cell array of character strings.

For example, x = 0:0.1:10; y = sin (x); lerr = 0.1 .* rand (size (x)); uerr = 0.1 .* rand (size (x)); errorbar (x, y, lerr, uerr); produces the figure The size of the ith slice is the percentage that the element xi represents of the total sum of x: pct = x(i) / sum (x). Octave Error Bars If no marker is specified it defaults to "o" or circles. Octave Errorbar Linewidth If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca.

See also: bar. There are better ways to do this, but for this % course, this is sufficient. Octave Plot Color
If a marker is specified then markers at the grid points of the vectors are drawn rather than arrows. h = bar (rand (10, 3)); set (h(1), "facecolor", "r") set (h(2), "facecolor", "g") set (h(3), "facecolor", "b") See also: barh, hist, pie, plot, patch.

Also please don't use html on the mail list. By default the columns are plotted side-by-side. Specify the values in data units. The most common form is semilogxerr (x, y, ey, fmt) which produces a semi-logarithmic plot of y versus x with errors in the y-scale defined by ey and the plot format
The xneg and xpos inputs set the left and right lengths of the horizontal error bars. The optional input stem_sz sets the width of each stem. See also: frame2im. Get More Info See also: plot, semilogx, semilogy.
It has two children, corresponding to the data plot and error bars respectively. The default for p is 0.1 seconds. Use this option after any of the previous input argument combinations. If more than one argument is given, they are interpreted as plot (y, property, value, …) or plot (x, y, property, value, …) or plot (x, y, fmt, …) and so
The following options affect the appearance of tic marks. "on" Turn tic marks and labels on for all axes. "off" Turn tic marks off for all axes. "tic[xyz]" Turn tic marks The color of bars can also be set manually using the "facecolor" property as shown below. Only line style and color are used; Any markers defined by style are ignored. The style to use for the plot can be defined with a line style style in a similar manner to the line styles used with the plot command.
contour3 plots level curves (contour lines) of the matrix z at a Z level corresponding to each contour. We respect your privacy and take protecting it seriously. If the argument 'filled' is given then the markers as filled. See also: meshgrid, contour.
The yneg and ypos inputs set the lower and upper lengths of the vertical error bars, respectively. We respect your privacy and take protecting it seriously. Additional arguments to the area function are passed to the patch. If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca.
