I'm using gnuplot in conjunction with a dotNet application which has a SQL =
Server backend. I am plotting data stored on the SQL Server.

I need to be able to manipulate the data being plotted on the graph. I need=
 to be able to draw a line which steps down from left to right,  when the d=
ata may include peaks and troughs which would otherwise mean the graph woul=
d go up and down.=20

I've worked out that I can do this is I check to see whether if the previou=
s next value along is higher than the previous, and if it is, assume the va=
lue of the previous and then plot a straight line.=20

Make much sense?
Thanks
