--- a/NEWS +++ b/NEWS @@ -1,6 +1,45 @@ Summary of important user-visible changes for version 3.0: --------------------------------------------------------- + ** Compatibility with Matlab graphics is much better now. We now + have some graphics features that work like Matlab's Handle + Graphics (tm): + + + You can make a subplot and then use the print function to + generate file with the plot. + + + RGB line colors are supported if you use gnuplot 4.2. Octave + can still use gnuplot 4.0, but there is no longer any way to set + line colors with it when using the Matlab-style plot functions. + Actually, there never was any way to do this reliably with older + versions of gnuplot (whether run from Octave or not) since it + only provided a limited set to choose from, and they were + terminal dependent, so choosing color 1 with the X11 terminal + would be different from color 1 with the PostScript terminal. + + + You can control the width of lines using (for example): + + line (x, y, "linewidth", 4, "color", [1, 0, 0.5]); + + (this also shows the color feature). + + + With gnuplot 4.2, image data is plotted with gnuplot and may be + combined with other 2-d plot data. + + + Lines for contour plots are generated with an Octave function, so + contour plots are now 2-d plots instead of special 3-d plots, and + this allows you to plot additional 2-d data on top of a contour + plot. + + + It is no longer possible to mix Matlab-style plot commands with + the old (and now considered obsolete) style of plot commands + (__gnuplot_set__, etc.). You can do one or the other, but not + both for the same plot. + + + Plot property values are not extensively checked. Specifying + invalid property values may produce unpredictible results. + + ** The way Octave handles search paths has changed. Instead of setting the built-in variable LOADPATH, you must use addpath, rmpath, or path to manipulate the function search path. These
