Here's a basic example of plot from the MATLAB documentation: The plot above uses the default MATLAB line width of 0.5 points. %example transfer function. Provided you have a reasonably recent version of Matlab: Why this work? You can do that in each call to plot by using the LineWidth parameter, like this: But then you have to remember to add the LineWidth parameter all the time. Here it is: This odd-looking line of code sets the default LineWidth property for line objects to 2.0. By continuing to use this website, you consent to our use of cookies. Other MathWorks country sites are not optimized for visits from your location. However, I cannot change alpha value or opacity, or transparency of the line. See the LineSpec parameter in plot for available line specifications. You can choose to plot data points using lines, or markers, or both. T=tf([1 1 1],[1 1 1 1 1]); Ts=1/10000; % tranasferfunction in z domain. Accelerating the pace of engineering and science. 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. Let me show you what I mean. Let’s go ahead a plot the following code. Consider the following graph made by: x=1:10; plot(x,'o-'); You can thicken a line by finding the elements of the line property. You would see something like this instead: Do you see the difference? If a run p1.Color it gave me a 1x3 vector, there's not a 4th component. Daniel's varycolor will give you that color set with a single command. Can you show the entire error message? Adding markers. Example: yline(C(2)) plots the line at the value of the second element in the array. For more information, see the function reference pages for startup and userpath. After some additional experimentation, I found that using 1.5-pt. Let's say I'm going to plot 50 lines. The line properties of the legend components cannot be changes independently from the line objects they represent in the plot. For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line. Can anyone guide how can I do it just by using scatter plot? So, the easiest solution is to change the line properties from within the plot. or. Based on your location, we recommend that you select: . If you want to do this for each MATLAB session, put the call to set into a file called startup.m that is located in your user path folder. So, I like to plot thicker lines, roughly 1.5-2.0 points. Location of the horizontal line on the y-axis, specified as a scalar.You can specify yvalue as a numeric, categorical, datetime, or duration value.However, the type of value you specify must match the data type for the values along the y-axis.. Making lines thick (or thicker) in MATLAB plots The default line size for MATLAB is 0.5pt, which is a bit annoying when integrating graphs into LaTeX. Here the values of first input are 5, 2, 6,1,4 and values of second input are 2,4,5,7,8. Follow 962 views (last 30 days) amir nemat on 2 Aug 2017. lines can make markers indistinct, and I can confirm that observation when not using a high-DPI monitor. And, to my eyes, that's too thin to see the colors clearly. Following is the code i'm trying out. Steve coauthored Digital Image Processing Using MATLAB. Today's blog post is dedicated to everyone whose eyes aren't as young as they used to be. That's because I don't use the default line thickness for my plots. Let us consider two inputs as x-axis and y-axis. You can set the default MATLAB linewidth property by setting the 'DefaultLineLineWidth' property of the root graphics object. For a full explanation of the MATLAB system for setting default graphics object properties, see Default Property Values in the MATLAB documentation. index 1 = true results in 1 <= thick < 2 ). For 3-D line plots, if you do not specify the x values, then MATLAB uses the indices of ZData as the x values for the plot. Update: Using a thicker line width might only work well for high-DPI monitors. Run the userpath function to see where that is. Choose a web site to get translated content where available and see local events and offers. Plot line thickness changes based on value. Just like it is to change the color of your plot in Matlab, the same goes for changing the line style, increasing the thickness of the line or some other aspect of it. I could only turn-on and off the grid using "zgrid" command. You will see updates in your activity feed.You may receive emails, depending on your notification preferences.

I'm trying to change the thickness of grid lines in pole-zero plot which is plotted using pzplot() command. 2 ⋮ Vote. If the value is false, the line should be thin, and if the value is true the line should be thick. The symbols can appear in any order. Because of the way the figure above was captured for display in your browser, the lines probably appear a little thicker than 0.5 points. polarplot(theta,rho) plots a line in polar coordinates, with theta indicating the angle in radians and rho indicating the radius value for each point.The inputs must be vectors with equal length or matrices with equal size. Commented: Tarek Saati on 27 Sep 2020 Accepted Answer: José-Luis. We do this with the linewidth attribute. When new lines are created, they will inherit this property from the root object. He also coaches development teams on designing programming interfaces for engineers and scientists. But now when I try to query the alpha value by typing simply. https://fr.mathworks.com/matlabcentral/answers/351255-how-can-change-transparency-and-thickness-of-a-line-in-matlab#comment_473918, https://fr.mathworks.com/matlabcentral/answers/351255-how-can-change-transparency-and-thickness-of-a-line-in-matlab#answer_276451, https://fr.mathworks.com/matlabcentral/answers/351255-how-can-change-transparency-and-thickness-of-a-line-in-matlab#comment_633125, https://fr.mathworks.com/matlabcentral/answers/351255-how-can-change-transparency-and-thickness-of-a-line-in-matlab#comment_764395, https://fr.mathworks.com/matlabcentral/answers/351255-how-can-change-transparency-and-thickness-of-a-line-in-matlab#comment_1026424. If you omit the symbol, then the outliers appear invisible. Do you like thicker plotted lines too? Tz=c2d(T,Ts); figure; pzplot(Tz); zgrid; 0 Comments. Because of the way the figure above was captured for display in your browser, the lines probably appear a little thicker than 0.5 points. lines on a high-DPI monitor works a little better. On a high resolution display, however, the plotted lines are pretty close to 0.5 points thick. a = linspace (2,6); b=cos(a); Output: This will plot the graph with the grid lines in the chart since the gridline option is ON. If 'PlotStyle' is 'traditional', then the default value is 'r+', which plots each outlier using a red '+' symbol. XData , YData , and ZData must have equal lengths. In this case, we set the line width equal to 10, giving the line of the graph plot a thickness 10 times the value of the default line width. Example: yline(8.45) plots the line at y = 8.45. I second Maximiliano's question: Why exactly does this work? Steve Eddins has developed MATLAB and image processing capabilities for MathWorks since 1993.

Here's mine: You can also use the userpath function to change your user path location, if you don't like the default location chosen by MATLAB. MATLAB: Plot line thickness changes based on value. If 'PlotStyle' is 'compact' , then the default value is 'o', which plots each outlier using an 'o' symbol in the same color as the corresponding box. x=-100:0.5:100; y=x.^5-x.^2; plot(x,y,'--r') And the plot will be. A marker is a small square, diamond or other shape that marks a data point. Get the MATLAB code (requires JavaScript) thnks man, saved the day... didn't get on my mind before, You may receive emails, depending on your. Can any one help. Where exactly is the alpha information stored? line(x,y) plots a line in the current axes using the data in vectors x and y.If either x or y, or both are matrices, then line draws multiple lines. And the line width value is 1. Because I just tried it in R2017a and I didn't get an error. It turns out that there's a way to get MATLAB to draw all plotted lines thicker by default. Find the treasures in MATLAB Central and discover how the community can help you! Hello, I'm trying to plot some boolean values, and to represent True (1) or False (0), I'd like to change the line thickness over time. Choose a web site to get translated content where available and see local events and offers. A straight line where only the thickness is dependent on the value, and if the value is true for 1, the line is thick for all of 1, if it is true for 2, the line is thick for all of 2, if the value is false for 3, then the line is thin for all of 3, and so on. It is with the plot() function that we specify the line width of the plot. This example illustrated in table 1. I have written the code in Matlab by using scatter.
