If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Setting the CreateFcn property on an existing component has no effect. If you do not specify the CreateFcn property, then MATLAB executes a default creation function. MATLAB initializes all property values before executing the CreateFcn callback. This property specifies a callback function to execute when MATLAB creates the object. MATLAB evaluates this expression in the base workspace.įor more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects. Subsequent elements in the cell array are the arguments to pass to the callback function.Ĭharacter vector containing a valid MATLAB expression (not recommended).

(That's what I did.)įor more information, see the function reference pages for startup and userpath.To use LaTeX markup, set the interpreter to 'latex'. You can also use the userpath function to change your user path location, if you don't like the default location chosen by MATLAB. For example, xline ( 12 20 33,'-b') creates three dashed blue lines. xline (x,LineSpec) specifies the line style, the line color, or both. For example, xline (2) creates a line at x2. '/Users/steve/OneDrive - MathWorks/MATLAB' xline (x) creates a vertical line at one or more x -coordinates in the current axes. 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. #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. #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. 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. 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. Here's where I have to wave my hands a little. 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. It also provides the ability to place text labels and specify the format and attributes of the line color, width, linetype, etc. If you ran my code exactly as I posted it, though, you probably wouldn't see exactly the same thing. The MATLAB function xline() creates and draws vertical lines at a specified point on the x-axis of a graph. In last week's blog post on pursuit curves, I showed this figure: Today's blog post is dedicated to everyone whose eyes aren't as young as they used to be.
