There are four line styles available in MATLAB: solid line, dash line, dotted line, and dashed-dot line. You can use these styles to make one plot different from another. For example, let's plot four sine waves in MATLAB with different line styles. See the below code.Themen. Create a 2-D line plot and specify the line style, line color, and marker type. Add markers to a line plot to distinguish multiple lines or to highlight particular data points. …Plot Single Data Series. Create a stem plot of 50 data values between - 2 π and 2 π. figure Y = linspace (-2*pi,2*pi,50); stem (Y) Data values are plotted as stems extending from the baseline and terminating at the data value. The length of Y automatically determines the position of each stem on the x -axis.

Modificar las propiedades de las líneas después de crearlas. En primer lugar, dibuje una línea del punto (3,15) a (2,12) y devuelva el objeto Line. A continuación, cambie la línea por una línea verde discontinua. Utilice la notación de puntos para establecer las propiedades. x = [3 2]; y = [15 12]; pl = line (x,y);

Topics. Create a 2-D line plot and specify the line style, line color, and marker type. Add markers to a line plot to distinguish multiple lines or to highlight particular data points. Create a plot with confidence bounds using the fill function to draw the confidence bounds and the plot function to draw the data points.Here are three ways to display multiple variable values on the same line in the Command Window.
