![]() ![]() Here we have discussed an introduction to Matlab Plot Legend with appropriate syntax and respective programming examples. I would like to have one unique legend below and outside (centred) the plots. Labels become very important when we plot multiple functions in the same graph. If you are working with a fairly recent version of Matlab (> R2014b I think) then you can edit an existing legend if you keep the handle to it: Theme. legend ('EONIA', 'EU Shadow Rate', 'Textual', 'Actual EONIA', 'Actual Shadow', 'Actual Textual', 'Orientation', 'horizontal', 'Location', 'southoutside', 'NumColumns',2) In the plot, I have 3 legends for each plot which are identical. We also learned to set the ‘direction’ and ‘Name’ of the label box as per our needs. We learned how to create labels in MATLAB plots and achieve desired styles. Legend (,'Location','northwest')Įxplanation: As we can notice in the output, our label box is now named. All we need to do is pass the pre-defined code for the direction, as an argument. any suggestions will be much appreciated. This places the legends at the south east location outside of each plot, but I want only one global legend for the whole subplot, not multiple individual legends. Legend function in MATLAB allows us to put our label in place of our choice. The legend command lets you specify the axis where the legend will be created: 'LEGEND (AX.) puts a legend on the axes with handle AX.' So if you get the axis handles when you create the subplots you can then specify the legend for each subplot. plot (x1,y1) legend ('old','new','Location','southeastoutside') end. Next, what if we don’t want our labels to be on the top right but in some other place on the plot. legend(h,string1,string2.) displays a legend on the plot. Per the doc, if you overwrite the area of a subplot, it deletes the existing one and creates a new one. displays a legend in the current axes using the specified strings to label each set of data. 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. The reason is still not entirely clear to me, but here is said. 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 a 2 by 1 grid of subplots for two plots one on top of each other a 1 by 2 grid. 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’. each component is given by rA -k1CA2CB - k2CACB2, rB -k1CA2CB - k2CACB2. 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. Set(a,'visible','off') %hide axes etc.Now to understand how ‘Legend’ works, we will first plot our input functions and then use the function ‘legend’. The legend command lets you specify the axis where the legend will be created: 'LEGEND (AX. You can also do it by code commands like this:įn = sprintf('%s_LEGEND',fn(l)) %give it a separate filenameĪ = get(gcf,'children') % link to ledgend is now a(1)ī = get(gca,'children') % link to the data curve/s You can then save that figure as Matlab figure o print it." quote from: Click on axis and data and hide them, the legend and the color bar will be the only things visible. Increase b to increase the space between the diagrams. This is the percent offset from the subplot grid of the plot box. "Just go to view and then to plot browser. Sometimes you will have a grid of subplots, and you want to have a single legend that describes all the lines for each of the subplots as in the following image. function AxisPos myPlotPos (nCol, nRow, defPos) Position of diagrams - a very light SUBPLOT.
