![]() (That's what I did.)įor more information, see the function reference pages for startup and userpath. You can also use the userpath function to change your user path location, if you don't like the default location chosen by MATLAB. Is there a simple, no fuss way in Matlab of drawing multiple vertical lines using xline (). '/Users/steve/OneDrive - MathWorks/MATLAB' Run the userpath function to see where that is. ![]() 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. This default setting does not persist between MATLAB sessions, though. lines on a high-DPI monitor works a little better. After some additional experimentation, I found that using 1.5-pt. lines can make markers indistinct, and I can confirm that observation when not using a high-DPI monitor. Blog reader Gang Yao pointed out that using 2-pt. Update: Using a thicker line width might only work well for high-DPI monitors. Hello would be the label for the xline, was just showing how you might have the label or not. to find the MATLAB has a built-in function parameters in the model equation. #XLINE MATLAB FULL#For a full explanation of the MATLAB system for setting default graphics object properties, see Default Property Values in the MATLAB documentation. now calculate the y values for each value of xline ylinexlinem. #XLINE MATLAB CODE#This odd-looking line of code sets the default LineWidth property for line objects to 2.0. Here it is: set(groot, 'defaultLineLineWidth',2.0) It turns out that there's a way to get MATLAB to draw all plotted lines thicker by default. The label only has limited options for positioning. xline(10, 'r', 'DisplayName', 'Hello') More importantly, replacing the label and DisplayName with empty strings does not remove that element from the legend. The label only has limited options for positioning. You can do that in each call to plot by using the LineWidth parameter, like this: plot(x,y1,x,y2, 'LineWidth',2.0)īut then you have to remember to add the LineWidth parameter all the time. The xline function by default goes to the limits if the y-axis. So, I like to plot thicker lines, roughly 1.5-2.0 points. On a high resolution display, however, the plotted lines are pretty close to 0.5 points thick.Īnd, to my eyes, that's too thin to see the colors clearly. 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. xLine,yLine rotateCordiantes(xLine,yLine,pi/2) plot(xLine+centerRwheel(1),yLine+centerRwheel(2). Here's where I have to wave my hands a little. This diagram was created with MATLAB by Jahobr. The plot above uses the default MATLAB line width of 0.5 points. ![]() Here's a basic example of plot from the MATLAB documentation: x = linspace(-2*pi,2*pi) That's because I don't use the default line thickness for my plots. You would see something like this instead:ĭo you see the difference? Exactly what you see will vary depending on your computer and your display resolution, but the original image from my blog post has thicker colored lines. If you ran my code exactly as I posted it, though, you probably wouldn't see exactly the same thing. In last week's blog post on pursuit curves, I showed this figure: It does not store any personal data.Today's blog post is dedicated to everyone whose eyes aren't as young as they used to be. The second argument of line is a list of the y values corresponding the x elements, so it will make a line from (x1, lower y limit) to x1, upper y limit).
