![]() In this article, we shall see how to add legends to single and multiple cartesian axes in MATLAB with various examples. Give it a try and let us know what you think here or leave a comment for Chad. MATLAB provides the legend () function to add legends to a set of axes, which makes legend-making easy and efficient. Of operation and tweak it in order to adapt it to your needs. that there are only 20 data points), matlab plot comes out to be a continuous one. This is a good example of how you can take a normal mode Notice the legend is at the top right corner. For each line plotted, the legend shows a sample of the line type, marker symbol, and color beside the text label you specify. ![]() If you want to see more examples, check out his published example.Ĭhad explains that legappend simply deletes the current legend and recreates the updated legend. Description legend places a legend on various types of graphs (line plots, bar graphs, pie charts, etc.). Great! You can also delete the last legend entry with the following command. This means that you can simply call it along with the new lines you To add this entry to the legend, you would re-run the legend command with the three entries.Ĭhad's legappend allows you to append new entries to an existing legend. Let's say that you wanted to add another line to this plot. Many of you may know that the command legend creates one legend per axes. You also can create a legend with multiple columns or create a legend for a subset of the plotted data. These examples show how to create a legend and make some common modifications, such as changing the location, setting the font size, and adding a title. ![]() His entries are well-written, and like this one, many of his entries have published example files. Legends are a useful way to label data series plotted on a graph. He has over 50 File Exchange entries, and two of his entries have been highlighted ( unit converters and ccc) in Pick of the Week. Jiro's pick this week is legappend by Chad Greene.Ĭhad is no stranger to MATLAB Central.
