Subject: [amibroker] Plotting Zero Axis Trend Bar
How do you plot a thick horizontal line at the bottom of a graph?
For example, I have a trend system, and I would like to plot the OHLC,
with a colored bar on teh bottom (green and red). I don't have an
issue with the colors, but just getting a thick bar at the bottom. I
can plot a really thin line, but that's too thin.
