I'm trying to use gnuplot with latex to create a nice looking graph that demonstrates integration by rectangular approximation along the y axis. The curve is drawn via parametric mode (has to be since there are multiple y values per x value). I figured out I can use multiplot to first plot the curve, then unset parametric to draw the bar graph - but I can't figure out how to get horizontal bars instead of vertical bars. Sure - I could theoretically use the gimp to manipulate an image created by gnuplot - but I'd rather do it in gnuplot simply because gnuplot integrates nicely with latex with respect to using latex formatting for the math stuff. The only other way I can think to do it would be to have gnuplot draw the horizontal lines and then draw the vertical lines - but that seems like a rather convoluted way of doing what *should* be as easy as having it draw horizontal bar graphs. Any ideas?
