I want one rectangle for x<1 region The function does not have a direct handle for color. Then I want a box in the upper right corner which names each of the two graphs. So in a sense to apply a separate colormap to the line plotted by plot like for example in a waterfall plot. Thanks! matlab; textbox; Using different colors for text plot annotations. Note that the RGB color specs that you provided happen to be the first 4 default colors that Matlab will use in a plot so I've changed them in this example so that we could see that the colors actually change. How to color multiple lines based on their value? Hot Network Questions Thanks for contributing an answer to Stack Overflow! Please be sure to answer the question. my goal is to create a colorbar to represent the colors of data lines plotted on a figure the color of the lines follow the jet colormap pattern, so I feel this should be possible to do in Matlab Skip to content.

It has nothing to do here. i have two groups of lines, one group in blue (4 lines) and the second in red (3 lines) at the same plot. ; Decide how many different plots you want and split your concentration values into the bins. The code that I am writing is: x=1:1: MATLAB : Plot multiple lines in a single graph with different colors and Legend them. My code plots all the lines the same color. If you do not specify a line color with plot and plot3, these functions cycle through the ColorOrder property to obtain the color for each line plotted. You can specify the color explicitly for each line, or let MATLAB select from the current color order. At the moment I have something like this: for j=1:n plot(j,total,'*') hold on end total changes in each iteration as well as j. I know only these 5 colors and markers in Matlab to differentiate between them. I want to plot VI with time in ONE LINE provided that each period has different color. Each 'blade' plots a separate line. I looked all over the internet, hope somebody have a suggestion to solve it. You cannot specify different Name,Value pairs for each line using this syntax. for k = 1 : numPlots. The following is a part of my matlab code. The documentation states that 'bar' will draw a bar for each column .
