How do you plot two lines with the same color in MATLAB?

Direct link to this answer

  1. col = [1 0 0] %RGB triplet,
  2. a= plot(1:5,1:5,’Color’,col)
  3. %or.
  4. b= plot(1:5,1:5,’Color’,’r’) % r for red.
  5. %you can set both lines to a different color at once:
  6. set([a b],’Color’,’b’);

How do you use RGB triplets in MATLAB?

Using RGB triplets to change colors 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.

How do you plot multiple lines of best fit in MATLAB?

How do I plot multiple lines of best fit on a scatter plot?

  1. xlim([0 105]) ; scatter(x1,y1, ‘g’, ‘Linewidth’, 5) Fit1 = polyfit(x1,y1,1); plot(polyval(Fit1,x1));
  2. hold on. scatter(x1,y2, ‘r’, ‘Linewidth’, 5) Fit2 = polyfit(x1,y2,1);
  3. hold on. scatter(x2,y3, ‘b’, ‘Linewidth’, 5) Fit3 = polyfit(x2,y3,1);

How do you add color to a plot in MATLAB?

You can change the colors, line styles, and markers of plot objects by modifying the ColorOrder or LineStyleOrder properties of the axes, or by changing the SeriesIndex properties of the plot objects.

How do you set plot colors in MATLAB?

Create a line plot and use the LineSpec option to specify a dashed green line with square markers. Use Name,Value pairs to specify the line width, marker size, and marker colors. Set the marker edge color to blue and set the marker face color using an RGB color value.

Can there be multiple lines of best fit?

It is certainly possible (in mostly silly cases). For example, suppose you sample the same x value twice and get two experimental y values that differ. One such case might be getting the points (0,−1) and (0,1) if we sample x=0 twice.

How do I set the color of a line in MATLAB?

You can use the linespec argument to specify a named color, but to specify a custom color, set an object property. For example, Line objects have a Color property. Create a plot with a purple line that has circular markers. Specify only the line and marker symbols in the linespec argument.
