The 7470A plotter has seven hardware linestyles.
Linestyle 1 is solid, and linestyles 2 - 7 are combina-
tions of dashed and dotted lines.
Colors are referred into the 7470A by the number of
the pen and not by the pen holder. This gives the
flexibility of more than.two colors on the plotter. By
default, index 1 is held in pen holder 1 and index 2 is
held in pen holder 2. If the user is using more than
these two colors, then a prompt will be generated,
telling the user to insert the desired color in a pen
station and then enter the pen station. So, the index
parameter in the routines that refer to a color index
corresponds to a pen number not a pen holder (i.e.
index 1 corresponds to pen 1, index 2 to pen 2, index
3 to pen 3 ... ). There is no limit to the number of pen
indices available on the plotter.
No GDPs are available on the HP7470A.
The required escape function is available on this
device.
