What does this line do in plotting?

line(histImage, Point(bin_w(i - 1), hist_h - cvRound(hist.at<float>(i - 1))), Point(bin_w(i), hist_h - cvRound(hist.at<float>(i))), Scalar(255, 255, 255), 2, 8, 0);

please take another look at the tutorial

it is just a visualization of the histogram values, drawing a line from each point to the next.

since y points down in opencv, the y values are inverted inverted (subtracted from the upper border)
