Remember that in images, white is data present. When you superimpose the large amounts of white from the top image on top of the grid on the bottom, then almost everything is going to turn white, leaving you with only a few dots where the curved line from the first happens to intersect the grid.

You may wish to consider converting to black and white, then inverting the image so that the black becomes true, doing a logical or of the two, then inverting again.

No, you do not have to do that: that is just a typical way of thinking about doing the addition of images.

In your particular case, you could instead AND the two images in their present form:

combine_image = FirstMatrix & SecondMatrix;

provided that they are the same size.

This will give 0 anywhere that either image is 0, which is equivalent to drawing in black.
