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. 'Linewidth' affects the line size, which is the thickness of the line between the data points, and the line that makes up the lines that comprise of the marker. 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. And is there a way to query the alpha value after it is set? See the LineSpec parameter in plot for available line specifications. Update: Using a thicker line width might only work well for high-DPI monitors. Here it is: This odd-looking line of code sets the default LineWidth property for line objects to 2.0. Accelerating the pace of engineering and science. It is with the plot() function that we specify the line width of the plot. In last week's blog post on pursuit curves, I showed this figure: If you ran my code exactly as I posted it, though, you probably wouldn't see exactly the same thing. I'm trying to change the thickness of grid lines in pole-zero plot which is plotted using pzplot() command. But now when I try to query the alpha value by typing simply. Provided you have a reasonably recent version of Matlab: Why this work? 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.. However, I cannot change alpha value or opacity, or transparency of the line. Matlab plotting line style. 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. I have already tried the following code but it gave me error. 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. So, I like to plot thicker lines, roughly 1.5-2.0 points. This example illustrated in table 1.
