histogram(image_of_dif)
will plot the histogram showing the distribution of values (both positive and negative differences).

histogram() by default plots the histogram, which is what your pic represents. And it shows the negative values as you expected, right?
The h is a histogram object, not an array to plot directly. For more details: https://www.mathworks.com/help/matlab/ref/matlab.graphics.chart.primitive.histogram.html
Please accept the answer if it works for you. Thanks!
