Why this happens… With plot(x(i),y) you are plotting 100 single points (one in each iteration) and they are not shown by default. Therefore the plot looks empty. Solution 1: Vectorized calculation and direct plot I assume you meant to draw a continuous line. In that case no for-loop is needed because you can calculate and … Read more
You could use a colormap such as HSV to generate a set of colors. For example: cc=hsv(12); figure; hold on; for i=1:12 plot([0 1],[0 i],’color’,cc(i,:)); end MATLAB has 13 different named colormaps (‘doc colormap’ lists them all). Another option for plotting lines in different colors is to use the LineStyleOrder property; see Defining the Color … Read more
Short answer : always use Set(‘Xdata’,…’). Example code: function PlotUpdate() x = 0:.1:8; y = sin(x); h = plot(x,y); y = sin(x.^3); set(h,’XData’,x,’YData’,y); end Long answer: There are three relevant measures by which one should choose the best method. Code clarity – How easy it is for someone to read your code? Runtime – How … Read more
