This command draws a hydrograph from a hydrograph file (*.h1) that
is
created by SEDCAD, the Hydrograph Development, or the Single Runoff
Hydrograph
command. Multiple hydrographs can be drawn on the same grid by first
running Draw Hydrograph with the Draw Grid option on. Then run Draw
Hydrograph
for each additional hydrograph with the Draw Grid option off and pick
the
same starting time and same lower left grid corner.
Range of Times: <0.0 - 49.998>
Starting time <0.0>: press Enter When
plotting
more than one hydrograph on the same graph as above, it is best to
reference
all starting times to 0. Some starting times will begin at 6
hours
or other value, but if they share a zero reference, they can be
overlaid
correctly by picking the same lower left corner of the horizontal and
vertical
axes.
Ending time <49.998>: press Enter
Draw Hydrograph settings dialog box. Because the
vertical
axis is typically very closely spaced in the hydrograph output files,
it
is recommended to set the vertical axis grid interval at 5 times the
vertical
scale, as shown in the dialog. For many cases, horizontal scaling
of
1 and vertical scaling of 1,5,1 in that order, work well for plotting.
Pick starting point for axis <0.0 , 0.0>: pick a
point
