I have a floor plan in a .jpeg or .png file, that I can read and display with the function image with the x-y coordinates. I also have another quantity, z, for a few, N, selected x-y locations of the floor coordinates. I would like to draw 3D bars at the appropriate N locations corresponding to the values of z. Would appreciate any help to do this.

You can plot image as a surface (on x-y plane) using the following code
%Insert Image
Z=imread('img.jpg');
[X,map]=rgb2ind(Z,256);
x=1:25; %change x,y to suite your requirements
y=1:25;
[xx,yy]=meshgrid(x,y);
zz=zeros(size(xx));
colormap(map)
surf(xx,yy,zz,X,'FaceColor','texturemap','EdgeColor','none','CDataMapping','direct');
After that use the function provided in the link below to plot the bar graph.

As for plotting of image is concerned, the size would be adjusted to fit your x,y grid, you probably won't have to worry about it. And for bar graph I have changed my answer a bit, please check that out.
