The location string can be all lower case and can be abbreviated by sentinel letter (e.g., N, NE, NEO, etc.). location can be either a 1-by-4 position vector () or one of the following strings. Uses location to determine where to place the legend. With no arguments refreshes all the legends in the current figure. Returns the handle to the legend on the current axes or empty if no legend exists. Removes the box from the legend in the current axes or the axes specified by axes_handle.Īdds a box to the legend in the current axes or the axes specified by axes_handle. Makes the legend in the current axes or the axes specified by axes_handle visible. Makes the legend in the current axes or the axes specified by axes_handle invisible. Otherwise, legend constructs a sting of the form data1, data2, etc. The default string for an object is the value of the object's DisplayName property, if you have defined a value for DisplayName (which you can do using the Property Editor or calling set). If no legend exists for the current axes, one is created using default strings. Removes the legend in the current axes or the axes specified by axes_handle. This is the same as legend(string_matrix(1,:),string_matrix(2,:).).Īssociates each row of the matrix string_matrix with the corresponding graphics object in the vector h.ĭisplays the legend for the axes specified by axes_handle. The font size and font name for the legend strings match the Axes FontSize and FontName properties.ĭisplays a legend in the current axes using the specified strings to label each set of data.ĭisplays a legend on the plot containing the objects identified by the handles in the vector h and using the specified strings to label the corresponding graphics object (line, barseries, etc.).Īdds a legend containing the rows of the matrix string_matrix as labels. When plotting filled areas (patch or surface objects), the legend contains a sample of the face color next to the text label. For each line plotted, the legend shows a sample of the line type, marker symbol, and color beside the text label you specify. Legend places a legend on various types of graphs (line plots, bar graphs, pie charts, etc.). Legend(li_object,string1,string2,string3) Legend('boxon'), legend(axes_handle,'boxon') Legend('boxoff'), legend(axes_handle,'boxoff')
Legend('show'), legend(axes_handle,'show') Legend('hide'), legend(axes_handle,'hide') Legend('toggle'), legend(axes_handle,'toggle') Here we discuss an introduction to Matlab Plot Legend with appropriate syntax and respective programming examples.Legend (MATLAB Functions) MATLAB Function Reference 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 PLOT 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 PLOT LEGEND 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.
MATLAB PLOT LEGEND 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
