I delete h_old and overwrite it with the new plots I created. Use dot notation to refer to a particular object and property: l legend ('show') l.Title.String 'My Title' l.Title.Color 'red' c l.Title.Color. By changing property values, you can modify certain aspects of the title. You also can create a legend with multiple columns or create a legend for a subset of the plotted data. stacked creates a bar for each row whose heights are each the sums of the elements on the row.
#Legend matlab how to
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. A somewhat different approach to Walters to generate the three needed bar handles - use a stacked plot with the elements on the diagonal, zero for the off-diagonal elements.
#Legend matlab series
H(2)=plot(points,modeldata2,'b-','DisplayName','Model Data, L= 0.2 m') Legend text properties control the appearance and behavior of the legend title. Legends are a useful way to label data series plotted on a graph. Second Plot (in the called function) h(1)=plot(points,modeldata1,'r-','DisplayName','Model Data, L= 0.1 m') I chose 0,250 because it's in the range of the data (otherwise it messes up the axis) Legend('-DynamicLegend','Location','Best')ĭrawnow forces the plot to be drawn right away, and h_old is just a "placeholder" that I make use of later on. Use dot notation to refer to a particular object and property: l legend ('show') l.Title.String 'My Title' l.Title.Color 'red' c l.Title. Plot(points,expdata3,'go','DisplayName','Experimental, L= 0.3 m') Legend text properties control the appearance and behavior of the legend title. You need to pass the x and y coordinate on which you want to place the text. We can also use the text () function to add text to the plot. Plot(points,expdata2,'bo','DisplayName','Experimental, L= 0.2 m') Add Custom Legends Using the text () Function in MATLAB. I was able to do it with a combination of solutions from different questions.Ĭlose all will ensure your plot starts anew every timeįirst plot (in my main) plot(points,expdata1,'ro','DisplayName','Experimental, L= 0.1 m') hold on How do I set an overall legend for all 4 subplots These subplots have exactly the same legend. If this still troubles you I can write a short snippet.I had a similar issue: I plotted three sets of experimental data first, then got into my parameter estimation to simulate the function and wanted to plot the model data every time, holding on to the experimental data but deleting the model data from the previous run. They display similar data, so I need only one legend for them. x linspace (0,pi) y1 cos (x) plot (x,y1) hold on y2 cos (2x) plot (x,y2) legend ( 'cos (x)', 'cos (2x)') If you add or delete a data series from the axes, the legend updates accordingly. The basic syntax is: legend( ‘Description 1’, ‘Description 2’, ).
#Legend matlab code
i have tried include legend in the loop so that the loop code becomes. The simplest way to use the function is to pass in a character string for each line on the plot. My problem is that i cannot figure out how i can include the legends in the plot. Specify the legend labels as input arguments to the legend function. The legend() function in MATLAB/Octave allows you to add descriptive labels to your plots. 2 demo to get pretty legend + Semitransparent rounded.
#Legend matlab download
change the values of left and bottom) and repeat until your conditions are met. Plot two lines and add a legend to the current axes. Download and share free MATLAB code, including functions, models, apps, support packages and toolboxes. What you can do next, is check if and which of your graphs in the plot cross paths with the legend (maybe define a relative distance function based on some distance threshold) and if they do, then randomly reposition the legend (i.e. Then, depending on the size of the frame (I would suggest you use axis() for this, if possible), you can pinpoint the position of the legend within the grid. These two values, left and bottom, specify the distance from the lower left corner of the figure to the lower left corner of the legend, and they are analogous to the grid frame you are using.
You will need to focus on left and bottom. Specify the legend labels as input arguments to the legend function. You should get something like this: ans = Plot two lines and add a legend to the current axes. So, you have tried using Location instead of Position? For example: x =1:100 Īnd you are getting odd results correct? A quick way of solving this would be to still use Location, with best, and extract the coordinates: lgd.Position
