Matlab Plot Legend Title

Title name value modifies the title appearance using one or more name value pair arguments for example fontsize 12 sets the font size to 12 points.

Matlab plot legend title. Specify the legend font size and title by setting the fontsize and title properties. This blog post was supposed to be a piece of cake. Specify name value pair arguments after all other input arguments. The main problem is with its position it doesn t seem to have such a property so once set i can t move it.

If mode is set to expand the legend will be horizontally expanded to fill the axes area or bbox to anchor if defines the legend s size. Add a title with the value of sin π 2. Bbox transform none or matplotlib transforms transform. Add a legend with two columns by setting the numcolumns property to 2.

Title with variable value. The transform for the bounding box bbox to anchor. For a value of none default the axes transaxes transform will be used. Create a chart with six line plots.

You can use a similar approach to add variable values to axis labels or legend entries. Today i will expand on that article by explaining the plot legend s internal graphics hierarchy how we can access each of these. First for some reason it makes it invisible but that is already solved in the code above. Include a variable value in the title text by using the num2str function to convert the value to text.

For the labels the legend uses the text from the displayname properties of the data series. Legend creates a legend with descriptive labels for each plotted data series. If the displayname property is empty then the legend uses a label of the form datan the legend automatically updates when you add or delete data series from the axes. Plot legends are essential for properly annotating your figures.

After all in hg1 r2014a and earlier a legend was a simple wrapper around a standard matlab axes. Somehow asking for the att output of the legend interfere with its title. Modifying the title appearance is not supported for all types of charts. The source code for the included examples can be found in the github.

Luckily matlab octave include the legend function which provides some flexible and easy to use options for generating legends. In this article i cover the basic use of the legend function as well as some special cases that i tend to use regularly. The problem description was that we wish to display a text title next to the legend box in plot axes.
