I want to plot (+,-) data in bar graph style with only positive Y axis

[DSMarcinko]

I have message traffic accross a buss (Receive and Transmit). I'd like to plot the message number as a (+) for transmit and (-) for receive. I'd like the messages to be conveyed as arrows up or down but I only want a positive Y axis. i.e. a 22T would be an arrow starting at zero pointing up to 22 where as a 22R would be an arrow starting at 22 pointing down to zero. Can this be done?

There are several ways to do this. You could use decorations on the front panel, but modifying them isn't real fun. You could try to customize a slide indicator, or maybe use the picture control. Basically you want the absolute value of a signal and arrows on top/bottom based on sign.

Instead of arrows, why don't you use some color coding as shown below ?

Since I need to graph this (data vs time) and I need to actively update the graph as I read the data. The best solution may be to use the color coding.

Thank you all for the input.
