fill(X,Y,ColorSpec) fills the polygons with the color specified by ColorSpec , which can be one of the following values: A color name or a short name: ‘red’ (or ‘r’ ), ‘green’ (or ‘g’ ), ‘blue’ (or ‘b’ ), ‘cyan’ (or ‘c’ ), ‘magenta’ (or ‘m’ ), ‘yellow’ (or ‘y’ ), ‘black’ (or ‘k’ ), ‘white’ (or ‘w’ ).

How do I set RGB color in MATLAB?

One can specify colors using a vector that gives the RGB triple where in MATLAB, each of the three values are numbers from 0 to 1. Usually RGB colors have values from 0 to 255. You can use those numbers and divide the vector by 255 to use within MATLAB. Thus knowing the MATLAB RGB triples for the colors can be useful.

How do you plot a red line in MATLAB?

Create a plot with a red dashed line and circular markers by specifying the linespec argument as ‘–or’ . For this combination, ‘–‘ corresponds to a dashed line, ‘o’ corresponds to circular markers, and ‘r’ corresponds to red. You do not need to specify all three aspects of the line.

How do you fill a plot marker in Matlab?

Direct link to this answer

  1. If you are only plotting markers, and not any lines, you can create a plot with filled markers by calling the scatter function with the ‘filled’ option.
  2. If you need to use the plot function, you can set the MarkerFaceColor property.

How to plot 3D MATLAB?

– Inserting a label for the x, y, or z axis – Inserting a legend to help readers – Rotating the plot in it’s 3-D space – Inserting a light source to show the effects of shadows

How to plot points in MATLAB?

Clear all active variables within the workspace by entering “Clear All” into the Command window.

  • Create two arrays of data as sample points to plot,with one array representing the x-data,the other the y-data.
  • Enter into the command window “plot (x,y,”.”) to plot the points.

    • How do I plot a point in MATLAB?

    Enter into the command window “plot(x, y, “.”) to plot the points. The “.” in the code places a “.” at each coordinate of the x-y matrix. For instance, a point will be placed at (1,2) and (2,4). Click on the “Show Plot Tools and Dock Figure” in the figure menu to change the marker type.

    What is the plot command for MATLAB?

    Plot command. In MATLAB you create a two dimensional plot using the plot command. The most basic form is. plot(x, y) where x and y are vectors of the same length containing the data to be plotted. Plot the function y = sin(2 pi x) for x in the interval [0, 1] using 401 equally spaced points.
