However, I can plot a line only one pixel long. I wonder why they do not simply provide the pixel plot primitive? I have seen very many graphics packages that do this and I have always wondered why. The primitive obviously exists in the underlying code, because that is what everything else is built upon. Does Tk actually have a something like a create_pixel method in the canvas widget that I have missed? -Bill
