You are defining a window through which you can see the image. The bottom of this window is *not* set to zero, it is auto configured. If all of your data is above a certain value, there's usually no desire to show the part of the image that is below this value, the bottom of your window is thus set at a value above zero. With the "--lower-limit" option, you define the *maximum* value for the bottom of your canvas. With a lower-limit of 0, the bottom of the canvas cannot be higher than 0 on the y-axis.
