legend positions the legend based on a variety of factors, such as what objects the legend obscures. MATLAB displays only one legend per Axes. By default, the legend annotates the current Axes.
Remarks legend associates strings with the objects in the Axes in the same order that they are listed in the Axes Children property. Returns a handle to the legend, which is an Axes graphics object.
Specifies the legend for the Axes specified by h. Removes the legend from the current Axes or the Axes specified by h. legend(h,Strings)Īssociates each row of the matrix Strings with the corresponding graphics object in the vector h. This is the same as legend(Strings(1,:),Strings(2,:).). legend(Strings)Īdds a legend containing the rows of the matrix Strings as labels. legend(' string1',' string2'.)ĭisplays a legend in the current Axes using the specified strings to label each set of data. After the legend appears, you can move it using the mouse. When plotting filled areas, the legend contains a sample of the face color next to the text label. For each line in the plot, the legend shows a sample of the line type, marker symbol, and color beside the text label you specify. Here we discuss an introduction to Matlab Plot Legend with appropriate syntax and respective programming examples.Legend (MATLAB Function Reference) MATLAB Function Referenceĭescription legend places a legend on a graph. 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.
#Legend matlab 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.
#Legend matlab code#
All we need to do is pass the pre-defined code for the direction, as an argument. Legend function in MATLAB allows us to put our label in place of our choice. Next, what if we don’t want our labels to be on the top right but in some other place on the plot. 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.
#Legend matlab series#
, 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. Hadoop, Data Science, Statistics & others
