I also want to change the legend so that it changes for each i. My mesh() plot gives me the the value of the function as a color how can i specify the color of the line plotted by joining the 2 points p1 and p2 according to its corresponding velocity from matrix 'normalized' OR 'averageV' I fail to see how we plot multiple different colours from this? I am looking for something where I can plot some number of lines with different colours on the same plot by hopefully providing a matrix of (nx3) or (3xn) numbers where the 3 is the rgb triplet and n is the number of lines. MATLAB : Plot multiple lines in a single graph with different colors and Legend them. Learn more about plot, plotting, legend . I can plot these fine, and by specifying the color above I am able to change the data points to red and blue to differentiate between the two models. The question was "How to set for each point a different color" and I believe I did that. You can change the colors in that list using the colororder function, and you can change the mapping of each color to its index into For example, when you plot multiple lines, MATLAB assigns each line a color from a set of colors according to their order of creation. But I want to make each curve with one unique color. Essentially, 4 plots would be on one figure. I'd like them to have all different colors.
