Image histograms provide a means to visualize the distribution of grayscale intensity values in the entire image. They are useful for estimating background values, determining thresholds, and for visualizing the effect of contrast adjustments on the image (next section). The matlab function to visualize image histograms is imhist

Both the contour and imagesc plotting styles plot only in the xy plane. Thus, you cannot use the zlabel command in conjunction with these plotting styles. If you use either of these styles, the axis command must also be modified to axis([xmin xmax ymin ymax]). Adjusting Figures. Zoom. Matlab lets you zoom in on a particular portion of the graph.
