The layout has a grid of tiles in the center, and four tiles along the outer edges. Name of font used for text rendering. Simply resizing manually a figure containing a legend shows the issue. In Octave 3.0.5: > plot (0:10) > legend ('linear','location','eastoutside') works as expected with the legend to the outside of the plot. This will plot the cosine and sine functions and label them accordingly in the legend. I am programing a function that plots a graphic and I need more than 6 colors. You will need to run system ("fc-cache -fv") manually after installing new fonts. Multiple locations can be specified if x, y, (z) are vectors. The four elements of the vector are the coordinates of the lower left corner and width and height of the legend. Unfortunately I cannot remember any details. See bug #39697. I can reproduce it with recent Hg archive. Some terminals have more than 6 colors, and the colors change depending on the terminal. Apart from the fact that the legend overlays with the second y axis label (which it doesn't on my screen, only when printing to jpg), the problem is that Octave appears to plot two legends on top of each other for some reason: one with the first set of data attached to the first set of axes, and one with the complete set of data, for both axes right on top of the first legend. as follows: The optional parameter orient determines if the key elements are The contents of the key, i.e., the names given to each plotted data set and function and samples of the lines and/or symbols used to represent them, are determined by the `title` and `with` options of the {`s`}`plot` command. Specify the position of the legend excluding its title. "vertical" (default) or "horizontal". In this case, the legend seems like a good spot to display the input to the free-vibration equations above. Function Reference: colorbar Octave-Forge - Extra packages for GNU Octave Axes Properties (GNU Octave), Ratio between the x/y/zlabel fontsize and the tick label fontsize.

Graphics handles to the text and line objects which make up the legend. of the current figure with the "tag" set to "legend". List of labels for the legend items. set. "none" turns off the default positioning algorithm and allows the user to set the location directly with the "position" property of the legend object. placed vertically or horizontally. If none is found then text is rendered using a default sans serif font (same as the default "*" value). > > Thanks > Reza When you create the legend, the function returns the handle to the legend. [0.13000 0.11000 0.77500 0.81500] Specify the position of the plot excluding titles, axes, and legend. A cell array of strings of the labels in the legend. The four elements of the vector are the coordinates of the lower left corner and width and height of the legend. Create a text object with text string at position x, y, (z) on the current axes. Consider what would have happened if we had not included the hold on command. It seems to be due to the fact that the axes "keypos" property used to be of type double or string. Control the variant of the base font used for text rendering. Properties of legend objects (see legend): Control whether the number of legend items is updated automatically when objects are added to (or deleted from) the peer axes.

In addition to the setting the location, the legend () function also allows you to set the orientation of the legend to either ‘vertical’ (default) or ‘horizontal’. This is a known issue, the legend position is not updated when its corresponding axes position changes. 3 Comments. Units used to interpret the "position", property. string: string | cell array of strings. If the handles, With the recent graphics code merge, the property has been turned into a double-only property. New release of Octave Forge To celebrate the release of Octave 3.2, a new release of the package have been made. Closing report as duplicate of the above.

FTR, now that fltk is used for generating the documentation we can see that the lack of listener on figure "position" property is also an issue: when printing a figure using a non default size ("paperposition" is changed) the figure position is changed before printing and the legend outline does not fit with the text entries. Tutorial to show how to customize a legend in Origin 2018 by changing the symbol size and adding desired syntax to the legend such as a line and/or symbol. figure ('Position', [left bottom width height]) or even set (figure (#),'Position', [left bottom width height]) However, using these commands in Octave only produces a figure that auto-tiles with my command window. The argument limits should be a 2-, 4-, 6-, or 8-element vector. legend works on line graphs, hobjs, are not specified then the legend’s strings will be associated So Jan, you may also be able to control the location of the legend by using the 'Position' property however the method specified in the help function is via the 'Location' property but the help fails spectacularly in explaining how exactly to use it. with the axes’ descendants. Units used to interpret the "fontsize" property. Subplot are dynamic objects which adapt their size depending on neighbor axes size: when the second subplot appears it forces the first one to be resized hence the wrong legend position.
