You can do that in each call to plot by using the LineWidth parameter, like this: plot(x,y1,x,y2, 'LineWidth',2.0) But then you have to remember to add the LineWidth parameter all the time. Lightonz on 26 May 2020 1) Calling legend with only 1 argument returns a handle to the legend object and getting its position actually gives you the position of the box enclosing the legend, i.e. This gives a very nice red dot on yellow background that I want to use as a special symbol, but is there a way to make these red on yellow dots appear as such in the legend box? No matter what I do with hObj(2), nothing happened on the figure.Could you explain to me what this second handle is? I found a solution of the linewidth problem. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. The fontsize alone is a piece of cake. hLg.LineWidth=1; % make the legend axes box linewidth smaller Presuming hobj is the handle of the figure or returned by whichever function used to plot in the axes, hl above is the line in the graph equivalent to hL above. Code: Xaxis =[ 5 2 6 1 4]Yaxis =[2 4 5 7 8 ]plot(Xaxis , Yaxis ,'LineWidth', 1) Output: Let us consider two inputs as xaxis and yaxis. https://www.mathworks.com/matlabcentral/answers/328791-how-do-i-change-the-linewidth-and-the-fontsize-in-a-legend#answer_257990. Any input is appreciated. Other MathWorks country sites are not optimized for visits from your location. to change the linewidth inside the legend, but i cannot change (or i dind't found a way) to change the fontsize with this method. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. In plot command, you can straightaway write 'LineWidth' in plot() itself, but no so in fplot. within this select "box styling" option and see the value for "LineWidth". Link go to edit -> axes properties and this will open up a property inspector. I want to do this by adding a second legend (in an own "legend-window") to the figure As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure Here, I present PlotPub which is a collection of MATLAB functions and… Based on your location, we recommend that you select: . By changing this, you will be able to change the thickness of the axes in the figure. If you specify this property using a function handle, then MATLAB passes the Legend object and an event data structure as the first and second input arguments to the function. You may receive emails, depending on your. Any input is appreciated. Accelerating the pace of engineering and science. And the line width value is 1. Then you can change it's LineWidth property and create the legend using the new line's handle. As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure make this axes invisible, so you don't see it later in the plot add two "helping - lines", one solid and one dotted But in the legend, the width of the line before the plot (marker line) is connected to the linewidth of the plot itself. I use handles to modify my plots. As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure make this axes invisible, so you don't see it later in the plot add two "helping - lines", one solid and one dotted Other MathWorks country sites are not optimized for visits from your location. It is equally popular among students, researchersand professors. Setting 'LineWidth' for that object changes the linestyle of the line itself, not the same property at all as the axes. LineWidth — Width of box outline 0.5 (default) | positive value. from its parent axis which makes a certain amount of sense. which makes both the axis lines and the legend box line thicker. change the line characteristics in both as the legend reflects the characteristics of the associated line in the axes to which it belongs. Choose a web site to get translated content where available and see local events and offers. LineWidth — Box edge and whisker width 1 (default) ... MATLAB automatically updates the box color or outlier color of the BoxChart object when you change its SeriesIndex, or when you change the ... Alternatively, you can control the items in a legend using the legend function. I cannot reproduce the problem you describe. This code generates a plot that I would put directly on a paper. I was unsuccessful in finding a solution online. Then I tried to set the legend box lines thinner with, but it makes both the axis lines and the legend box lines thinner, Use the two object handles to set their respective properties--although. When you do that, the size of the font changes, however, the small line next to it has the same size than when it was small. This week, I'd like to highlight one of the new R2016a features that just came out a couple of weeks ago. The simplest way to use the function is to pass in a character string for each line on the plot. 24. LineWidth — Box edge and whisker width 1 (default) ...

MathWorks is the leading developer of mathematical computing software for engineers and scientists. Toggle Sub Navigation. I am using the below code to plot 3 lines and when I define the Line Style and Linewidth, the text in the legend disappears. I want to set the y1 label in the legend to have linewidth=7.0, while the y1 line featured in the plot has a different width (linewidth=1.0). hLg.LineWidth=1; % make the legend axes box linewidth smaller Presuming hobj is the handle of the figure or returned by whichever function used to plot in the axes, hl above is the line in the graph equivalent to hL above. The line properties of the legend components cannot be changes independently from the line objects they represent in the plot. By changing this, you will be able to change the thickness of the axes in the figure. There are so many exciting features, and the one I'll be talking about today is related to a Pick from a while ago on clickableLegend by one of our ex-MathWorkers, Ameya. I am using the below code to plot 3 lines and when I define the Line Style and Linewidth, the text in the legend disappears. This property value is the default for GeographicAxes objects. I am playing with the visual effect of plots, and a question came up while changing the style of a legend.. To be able to save the figure with legends big enough that can be seen usually one needs to change the FontSize property to e.g. This code generates a plot that I would put directly on a paper. For example: I found a solution of the linewidth problem so changing one or the other (or both) will change the length of the line displayed in the legend box. This property value is the default for Axes and PolarAxes objects. OK, thanks, i didn't look carefully enough at the doc legend, but I found that even if I only plotted 1 line, and set up 1 legend, I can find two line object in hObj, only the first handle in hObj is the real line handle, because I set its linewidth, I saw the change. There are the various operations of lines in Matlab in which line width is one of the operations. So, I like to plot thicker lines, roughly 1.5-2.0 points. OK, thanks, i didn't look carefully enough at the doc legend, but I found that even if I only plotted 1 line, and set up 1 legend, I can find two line object in hObj, only the first handle in hObj is the real line handle, because I set its linewidth, I saw the change. The legend function will actually generate the coordinates for the upper-left hand corner of the box (that's where I got 9.46 and 346.62) along with the width and height of the box. box on displays the box outline around the current axes by setting their Box property to 'on'. This table describes the fields in the event data structure. Let us consider two inputs as x-axis and y-axis. But in the legend, the width of the line before the plot (marker line) is connected to the linewidth of the plot itself. OK, thanks, i didn't look carefully enough at the doc legend, but I found that even if I only plotted 1 line, and set up 1 legend, I can find two line object in hObj, only the first handle in hObj is the real line handle, because I set its linewidth, I saw the change. This example illustrated in table 1. h = plot (x,y, 'LineWidth', 1.5); No matter what I do with hObj(2), nothing happened on the figure.Could you explain to me what this second handle is? I use handles to modify my plots. And, changing it. I am generating a legend with 4 columns and 22 total items. But the changing of the two properties gave me a hard time. MATLAB is an excellent tool. Find the treasures in MATLAB Central and discover how the community can help you! Introduction to Matlab LineWidth. Learn more about box plot, outliers, markersize, legend, statistic analysis, marker size for outliers MATLAB Here is the whole code with comments; I changed the length and linewidth of the line in the 2nd plot to highlight the changes. The only related issues had answers for changing the linewidth of the legend bounding box through leg.get_frame().set_linewidth(7.0). hLg.LineWidth=1; % make the legend axes box linewidth smaller Presuming hobj is the handle of the figure or returned by whichever function used to plot in the axes, hl above is the line in the graph equivalent to hL above. That is a builtin connection that is immutable without trickery to create secondary lines such that the connection between which legend entry is shown and the given line is disguised by creating hidden objects or similar. 2) Using this line: p … As long as there is a 'String' entry for each object in 'PlotChildren', it will be rendered in the legend. Accelerating the pace of engineering and science. You may receive emails, depending on your. Lightonz on 26 May 2020 Toggle Sub Navigation. Jiro's pick this week is a feature that allows you to create interactive legends using callbacks.. It turns out that there's a way to get MATLAB to draw all plotted lines thicker by default. for that object changes the linestyle of the line itself, the same property at all as the axes. Find the treasures in MATLAB Central and discover how the community can help you! box off removes the box outline around the current axes by setting their Box property to 'off'. MATLAB Answers. To update our legend object without calling legend again, we can modify the 'PlotChildren' and 'String' properties of our existing legend object. Setting 'LineWidth' for that object changes the linestyle of the line itself, not the same property at all as the axes. The fontsize alone is a piece of cake. OK, thanks, i didn't look carefully enough at the doc legend, but I found that even if I only plotted 1 line, and set up 1 legend, I can find two line object in hObj, only the first handle in hObj is the real line handle, because I set its linewidth, I saw the change. Reload the page to see its updated state. The basic syntax is: legend (‘Description 1’, ‘Description 2’, … Simon shared a nice, easy-to-use function to create multi-column figure labels. MathWorks is the leading developer of mathematical computing software for engineers and scientists. the text + the line. If you want the change the legend representation without changing the line property, you can copy the line and replace its XData and YData with NaN values so it doesn't appear in the plot. within this select "box styling" option and see the value for "LineWidth". is the handle of the figure or returned by whichever function used to plot in the axes, above is the line in the graph equivalent to. The legend () function in MATLAB/Octave allows you to add descriptive labels to your plots. As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure make this axes invisible, so you don't see it later in the plot add two "helping – lines", one solid and one dotted Return the two “Line” objects as an output argument from the “plot” function and then set the “LineWidth” property for each. Plot operation is used to plot the input and output in a … Unable to complete the action because of changes made to the page. 1. extra lines in legend box fitted line to data MATLAB Answers. I have troubles reducing the legend lines length and legend box accordingly such that it does appear nicer. I want to do this by adding a second legend (in an own "legend-window") to the figure As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure Line width is used to adjust (increase) the width of any object. A brute force (not very elegant) kind of thing I often do (Matlab 2015b, but should work in all) is to create a new plot of a single point (on the same figure) with the same marker type and the size you require in the legend. BubbleLegend properties control the appearance and behavior of a BubbleLegend object. No matter what I do with hObj(2), nothing happened on the figure.Could you explain to me what this second handle is? To plot two lines with different line widths, you can use either of these approaches. But the changing of the two properties gave me a hard time. NOTE: Functionality similar to this File Exchange entry was added to MATLAB in R2018a.See the NumColumns Property to legend.. Today's Pick is another that is an author's first submission to the File Exchange. The legend displays fine in MATLAB's figure window, but when I export the figure to pdf (or any other format I've tried), the text is all jumbled in one corner of the figure. So, the easiest solution is to change the line properties from within the plot. Line width operation mostly executes inside the plot operation. It doesn't matter if I use export_fig or print.
