Matlab plot point color
My code looks something like this(very simplified). while yApr 22, I want to plot every one of these complex numbers in the complex plane in such a way that: If RegionsMap(k,j) is 1 I color the associated point .
caxis ([1,n]) where n is the number of entries. Now value K will be drawn with color from entry #K Sign in to answer this question. Create a colormap with as many entries as values you have.
How do I make all the points in a different color than the default blue I get. Thanks in advance. Hi. Im trying to make a plot change its color and having a hard time. My code looks something like this (very simplified): while yplot (x,y); hold on; end.
However, each command works as if it were generating a fresh plot, including starting with the first line color . hold on makes sure the new plot command adds to the plot instead of replacing it.

grid on;. cmap = jet(length(x)); % Make colors. title(' . % close to the edge use the red end of the colormap. ys = y(sortIndexes);. xs = x(sortIndexes);.
you can plot the graph, after that replot the point which you want. If you do not want to overlay a second plot on the first, you can plot each point individually and use handles. In that way, you can later perform. Try to hold on and then plot the point (x,y) which you want with the specified color (r) which you are interested in. 3 Answers.

Never, I don't typically share code. How often is your MATLAB code officially or unofficially reviewed?
The color values are passed as a fourth argument. The third argument is marker size (which can be fixed, or it can also have a different value for each point). 5 You can use scatter to plot all points in one go, with a different color for each point.
I tried different plot commands above (%) but nothing changed the situation. PROBLEM: It plots a color box everywhere but I want to display only the discrete values, the vacancies should be white or any known color.
