Basically, I want to make a legend for each type of rectangle. Here we discuss an introduction to Matlab Plot Legend with appropriate syntax and respective programming examples. I have the following picture : And I would like to make a legend for it. Labels become very important when we plot multiple functions in the same graph. We also learned to set the ‘direction’ and ‘Name’ of the label box as per our needs.
#Matlab legend how to#
We learned how to create labels in MATLAB plots and also how to achieve desired styles. Legend (,'Location','northwest')Įxplanation: As we can notice in the output, our label box is now named.
#Matlab legend code#
All we need to do is pass the pre-defined code for the direction, as an argument.
#Matlab legend series#
The legend updates automatically whenever we include any new or remove data series from the current axes. For labels, it uses one of the properties of data series which is known as DisplayName. Legend function in MATLAB allows us to put our label in place of our choice. In Matlab, legends are used to label the plotted data for every parameter that is mentioned. He has over 50 File Exchange entries, and two of his entries have been highlighted (unit converters and ccc) in Pick of the Week. Next, what if we don’t want our labels to be on the top right but in some other place on the plot. Jiro's pick this week is legappend by Chad Greene. Here, we can name our functions as per our needs.Įxplanation: Notice on the top right side of the plot, we have got the names of our functions.
In addition to the above code, we will add the below-mentioned line:Īs we can see, we have passed the name of the functions as an argument to our legend function.
Our initial code will be the same as in the above example Now, what if instead of ‘data1’ and ‘data2’, we want to have the name of the function as the label. Since nothing was passed as an argument to legend function, MATLAB created labels as ‘data1’ and ‘data2’. This is how our input and output will look like in MATLAB console:Įxplanation: As we can see in the above output, we have plotted 2 vectors and our legend function created corresponding labels. Our inputs A, B& C are first passed as arguments to the function ‘plot’.Īnd then we simply write ‘legend’ in our code to get the labels. Now to understand how ‘Legend’ works, we will first plot our input functions and then use the function ‘legend’. Next, we will define B as the cos function of values of A and C as sine function of values of A We will define an increment of π/50 between these values. Let us understand the function with an example: Example #1įirst, we will define ‘A’ as a vector containing values between 2pi (π) and 3π. The function ‘legend’ will create labels like ‘data1’, ‘data2’, and so on. , L N), where L1, L2 and so on represents the respective labels.Įxplanation: This function will create a legend for each data series used in the plot, with descriptive labels.
