373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	19 <li> RGB line colors are supported if you use gnuplot 4.2. Octave
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	20 can still use gnuplot 4.0, but there is no way to set arbitrary
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	21 line colors with it when using the Matlab-style plot functions.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	22 There never was any way to do this reliably with older versions
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	23 of gnuplot (whether run from Octave or not) since it only
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	24 provided a limited set to choose from, and they were terminal
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	25 dependent, so choosing color 1 with the X11 terminal would be
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	26 different from color 1 with the PostScript terminal. Valid RGB
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	27 colors for gnuplot 4.0 are the eight possible combinations of 0
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	28 and 1 for the R, G and B values. Invalid values are all mapped
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	29 to the same color.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	30 <p>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	31 This also affects patch objects used in the bar, countour, meshc
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	32 and surfc functions, where the bars and contours will be
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	33 monochrome. A workaround for this is to type "colormap gmap40"
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	34 that loads a colormap that in many cases will be adequate for
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	35 simple bar and contour plots.</li>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	36
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	37 <li> You can control the width of lines using (for example):
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	38 <pre>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	39 line (x, y, "linewidth", 4, "color", [1, 0, 0.5]);

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	41 (this also shows the color feature).</li>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	42
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	43 <li> With gnuplot 4.2, image data is plotted with gnuplot and may be
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	44 combined with other 2-d plot data.</li>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	45
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	46 <li> Lines for contour plots are generated with an Octave function, so
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	47 contour plots are now 2-d plots instead of special 3-d plots, and
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	48 this allows you to plot additional 2-d data on top of a contour
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	49 plot.</li>

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	51 <li> With the gnuplot "extended" terminals the TeX interpreter is
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	52 emulated. However, this means that the TeX interpreter is only
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	53 supported on the postscript terminals with gnuplot 4.0. Under
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	54 gnuplot 4.2 the terminals aqua, dumb, png, jpeg, gif, pm, windows,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	55 wxt, svg and x11 are supported as well.</li>

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	57 <li> The following plot commands are now considered obsolete and will
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	58 be removed from a future version of Octave:

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	66 Additionally, these functions no longer have any effect on plots
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	67 created with the Matlab-style plot commands
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	68 (<tt>plot</tt>, <tt>line</tt>, <tt>mesh</tt>, <tt>semilogx</tt>,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	69 etc.).

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	71 <li> Plot property values are not extensively checked. Specifying
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	72 invalid property values may produce unpredictible results.</li>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	73
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	74 <li> Octave now sends data over the same pipe that is used to send
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	75 commands to gnuplot. While this avoids the problem of
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	76 cluttering /tmp with data files, it is no longer possible to use
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	77 the mouse to zoom in on plots. This is a limitation of gnuplot,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	78 which is unable to zoom when the data it plots is not stored in
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	79 a file. Some work has been done to fix this problem in newer
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	80 versions of gnuplot (> 4.2.2). See for example,

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	85 <li>The way Octave handles search paths has changed. Instead of
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	86 setting the built-in variable <tt>LOADPATH</tt>, you must
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	87 use <tt>addpath</tt>, <tt>rmpath</tt>, or <tt>path</tt> to
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	88 manipulate the function search path. These functions will
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	89 maintain <tt>"."</tt> at the head of the path, for compatibility
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	90 with Matlab.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	91 <p>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	92 Leading, trailing or doubled colons are no longer special.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	93 Now, all elements of the search path are explicitly included in
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	94 the path when Octave starts. To display the path, use
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	95 the <tt>path</tt> function.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	96 <p>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	97 Path elements that end in <tt>//</tt> are no longer searched recursively.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	98 Instead, you may use addpath and the genpath function to add an
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	99 entire directory tree to the path. For example,
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	100 <pre>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	101 addpath (genpath ("~/octave"));
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	102 </pre>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	103 will add ~/octave and all directories below it to the head of the
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	104 path.</li>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	105
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	106
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	107 <li>Previous versions of Octave had a number of built-in variables to
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	108 control warnings (for example, <tt>warn_divide_by_zero</tt>). These
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	109 variables have been replaced by warning identifiers that are used
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	110 with the warning function to control the state of warnings.
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	111 <p>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	112 For example, instead of writing
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	113 <pre>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	114 warn_divide_by_zero = false;
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	115 </pre>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	116 to disable divide-by-zero warnings, you should write
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	117 <pre>
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	118 warning ("off", "Octave:divide-by-zero");

373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	120 You may use the same technique in your own code to control
373d2dba318e Include stuff from current octave.org for later hosting. Kai T. Ohlhus <k.ohlhus@gmail.com> parents: diff changeset	121 warnings. For example, you can use
