![]() You can also use copyobj to copy graphics elements from one figure to another if you have a lot of elements, then use set(x, 'visible', 'off') to hide them before showing the legend, but it depends on what your final application is. This will plot the additional points, but they will not be visible on the plot itself. The updated code above works, but the answer below is only relevant pre-2016b: figure To include a variable value in the text, use num2str. Set the 'DisplayName' property to a character vector of the text that you want to include in the legend. Control the label for the new data series by setting the DisplayName property as a name-value pair during creation. When you create a plot, you can specify the legend labels by setting the DisplayName property as name-value pair. Im trying to plot a graph with multiple plots on it and the legend is off. ![]() This will plot the additional points, but because the coordinates are at NaN they will not be visible on the plot itself:ĮDIT : My original answer results in greyed out legend entries in 2016b. If you add or delete a data series from the axes, the legend updates accordingly. The legend does not show the right marker. ![]() Resizing a Legend To resize a legend: Start plot editing mode by selecting Edit Plotfrom the figure Toolsmenu Right-click on its axes and select Unlock Axes Positionfrom the pop-up menu. That way, at the second iteration the plot from the 2nd iteration will be plotted, the plot from the 1st will be deleted and after these operations I get it to display the plot (again drawnow).This is how I have solved this problem in the past: figure MATLAB automatically resizes the legend box to fit long or multiline labels. I delete h_old and overwrite it with the new plots I created. You move the legend by pressing the mouse button while the cursor is over the legend and dragging the legend to a new location. positions the legend based on a variety of factors, such as what objects the legend obscures. Thus, I prefer a simple and working solution that rely on the original functionality of the legend title. MATLAB displays only one legend per Axes. I can think of some similar hacks by myself (like using text with the position of the legend), but my situation is very complicated, and I already configure the legend a lot and have several axes in every figure. Second Plot (in the called function) h(1)=plot(points,modeldata1,'r-','DisplayName','Model Data, L= 0.1 m') By default, the legend annotates the current Axes. I chose 0,250 because it's in the range of the data (otherwise it messes up the axis) 6 Answers Sorted by: 39 I do not like storing the handle values, it becomes a mess when I have a lot of graphs in my figures. 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. Plot(points,expdata3,'go','DisplayName','Experimental, L= 0.3 m') Las leyendas son una forma útil de etiquetar las series de datos representadas en una gráfica. Plot(points,expdata2,'bo','DisplayName','Experimental, L= 0.2 m') Use the Position property to display the legend in a custom location. 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. Basically, I want to make a legend for each type of rectangle. 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. Add Custom Legends Using the text () Function in MATLAB. In Matlab, legends are used to label the plotted data for every parameter that is mentioned. Matlab - how to make a custom legend Ask Question Asked 10 years, 9 months ago Modified 2 years, 1 month ago Viewed 23k times 10 I have the following picture : And I would like to make a legend for it. Specify the legend labels as input arguments to the legend function. ![]() 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 you change the legend in Matlab To move the legend to a different tile, set the Layout property of the legend. Plot two lines and add a legend to the current axes. 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. ![]()
