Snapshot 2

Later that day...


D: What are you doing?
S: I made this program to display a bar graph, but one of the bars is not displaying.
D: How does it draw the bars?
S: It uses a color block image and stretches it to the length needed for each line.
D: And the missing one was written as a zero length line?
S: No, I checked the source and there it says the bar is some length, not zero.
D: The image you are using is called blue_block.gif? Does that mean it's supposed to show a blue bar?
S: Yes.
D: But, don't these bars look kind of transparent?
S: Oh, you're right!
