[Plplot-general] Can PLplot do this?

[Schwab,Wilhelm K <bs...@an...>]

Hello all,

Suppose you were challenged with producing exactly the attached output.  Do you have any thoughts on clever ways to do it using PLplot?  Are there things you would advise NOT doing? :)   To say I need exactly the displayed output is too strong; it was produced using gnuplot and is itself a compromise.  However, it gets a few things right; in particular, distinguished major and minor grid lines are a must.

Not that it really matters, but the data are blood pressures (measured a couple of different ways, hence the different symbols), and heart rate.  The minor grid lines are spaced at 15 minutes, but I could just as easily (and did so here) express time in seconds.  The vertical range of the numbers is 0-250 with heavy grid lines every 50 units.

I don't expect much in response to this.  I offer it as an example of some things that I find missing in PLSYM (mostly, the open/filled up/down trianagles are not all present?? - up/down arrows could take the place of one set) and in the hopes that somebody will offer some terse but insightful advice about how to tackle problems that might arise in "cloning" this using PLplot.  For example, would you try to get PLplot to create the grid "itself" or perhaps just draw horizontal and vertical lines at the correct places?
