How To Use Patch Command

I have to plot my data on two y axes sharing one x axis. This can be done using plotyy. How do I overlay two patch plots such that one patch is on each y axis? Fruit Ninja Frenzy For Pc Windows Xp.

There are a number of ways to, and a number of ways to. Here's a way to create your coordinate data without a for loop and plot and color your patches with a single call to the function: x = [NaN 1 3 7 9 23 8];%# Sample x data y = [NaN 2 6 7 8 2 1];%# Sample y data z = [NaN 1 4 5 5 4 1];%# Sample z data N = numel(x);%# The number of sample data points X = [x; x([1 1],[N 1:N-1]); x];%# X coordinates (one patch per column) Y = [y; y([1 1],[N 1:N-1]); y];%# Y coordinates (one patch per column) Z = [z; z([N 1:N-1]); zeros(2,N)];%# Z coordinates (one patch per column) C = round(63.*Z./max(Z(:)))+1;%# Color map index map = [linspace(0,1,64).' .%'# Color map (64 values spanning from ones(64,2)];%# white to cyan) figure();%# Open a new figure patch(X,Y,Z,C,'FaceColor','interp'.%# Plot the patches 'EdgeColor','none'); colormap(map);%# Update color map hold on;%# Add to the plot line(X(1:2,:),Y(1:2,:),Z(1:2,:).%# Plot the line 'Color','b','LineWidth',2); view(3);%# Change the view And this will give you the following plot, with patches colored white at the highest values and fading to cyan at the lowest values: Explanation of the indexed color mapping. The variable map above is a 64-by-3 matrix of values between 0 and 1.

Each row represents an, thus defining a unique color ranging from cyan in row 1 to white in row 64. Calculus 1 Pre Calculus. This is used as the figure color map.
