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). Debe pasar las coordenadas x e y en las que desea colocar el texto. También podemos usar la función text () para agregar texto al gráfico. I delete h_old and overwrite it with the new plots I created. Agregue leyendas personalizadas usando la función text () en MATLAB. Accepted Answer: Ameer Hamza I have the following string: Now I want to use this string to produce a legend to my figure. If you want to set the position to a rectangle, use the 'Position' property: Theme Copy rect 0.25, 0.25. EDITED: The 'Location' property uses the strings 'southeast', 'northeast', 'best' etc. H(3)=plot(points,modeldata3,'g-','DisplayName','Model Data, L= 0.3 m') 11 Link 'set (h,'Location','rect')' uses the string 'rect', but you want to use the variable. If you do not specify a label, then the legend uses a label of the form dataN.

Control the label for the new data series by setting the DisplayName property as a name-value pair during creation. Second Plot (in the called function) h(1)=plot(points,modeldata1,'r-','DisplayName','Model Data, L= 0.1 m') If you add or delete a data series from the axes, the legend updates accordingly. Bubble legends are useful for showing the relationship between the bubbles and the size data for. I chose 0,250 because it's in the range of the data (otherwise it messes up the axis) bubblelegend creates a bubble legend in the current axes. 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') Plot(points,expdata2,'bo','DisplayName','Experimental, L= 0.2 m') 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 Edit: After some experimentation, I found that there is a maximum size of marker that legend will show, which is about 10. You also can create a legend with multiple columns or create a legend for a subset of the plotted data.

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.
If you don't want that, you will need to create dummies with NaN. Legends are a useful way to label data series plotted on a graph. Le.String = %%% changed: append new stringĪs a side note, speaking of performance, you may want to replace clear all by clear see relevant links: 1, 2, 3.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. Ran in: This is only possible by increasing the size of the markers themselves in the plot. So I use and get this: But I would like to have this, which I got by using the following. 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. Specify the legend labels as input arguments to the legend function. MATLAB automatically resizes the legend box to fit long or multiline labels.

Again, the main reason for this is that the code arguably looks cleaner, as you avoid keeping the same information in two places (the variable and the graphical object): clear all close all clc I have the following string: Now I want to use this string to produce a legend to my figure. Plot two lines and add a legend to the current axes.
#Legend matlab update#
Le.String = str %%% changed: update String property of the legendĪlternatively, you can avoid storing str, and directly append the new part to the legend. Le = legend(str, 'Location','southwest') %%% new: create empty legend 2 demo to get pretty legend + Semitransparent rounded.

In your example code this will hardly have any impact, but it still looks like a cleaner approach: clear all close all clc Download and share free MATLAB code, including functions, models, apps, support packages and toolboxes.
This "update instead of re-create" idea is common practice for graphical objects that change with time, and results in faster execution. Basically, I want to make a legend for each type of rectangle. An improvement would be to update the String property of the legend, instead of creating a new legend in each iteration.
