graphics: REPRESENTATION: item
Polymarker item: can be used as marker type argument to the
PLOT_MARKER procedure.
Is initialised to be an asterisk, of which you can change the
size and colour.
Polyline and polymarker item: Auger electrons result from
the return of an excited atom to a lower energy state by the
emission of an electron rather than a photon - an mechanism
known as Auger effect. The electron that is emitted may have
enough energy to ionise further gas molecules, in which case
these electrons look like delta electrons.
If an Auger electron generates secondary electrons, then a
line is drawn showing its trajectory. Otherwise a marker
indicates the point where it was produced.
Polyline and fill area item: the polyline item corresponds to
the coordinate axes, the fill area item is used in
3D diagrams for the 3 backmost panels
of the box.
The fill area item should in principle have an interior style
of SOLID
and a light colour. The colour will not be used as such - rather,
various shades will be used depending on the exposition of the panel
with respect to the light source.
Polymarker item: can be used as marker type argument to the
PLOT_MARKER procedure.
Is initialised to be a circle, of which you can change the
size and colour.
Polyline and text item: the polylines clarify lines such as
boundaries and changes in status of drift lines.
The text item is used for the information underneath the title
and also to explain what the polyline of the same type mean.
Fill area item: conductors in the chamber as entered with the
SOLIDS statement, but also the wires when asking
for a 3D plot of a chamber in which the
field is computed from wire locations rather than a field map.

should in principle be set to
SOLID.

a polyline representation is needed.
The representation is not used by normal Garfield commands.
Polyline and polymarker item: Delta electrons look like a
hairs along the track. They result from particularly large
energy transfers of the particle to an electron of a gas
molecule. The electrons thus liberated from the molecule
have sufficient energy to ionise further gas molecules before
drifting towards the anodes.
If the delta electron generates several further electrons,
then it will be drawn as a line, otherwise as a marker.

gas molecule.

(PLANE statement). The fill area item is used
in 3D layouts, the polyline item is
used for other projections.

with WIRES.
Text item: the global title of the plot.
Polyline and polymarker item: This can be either of 2 things:
- the straight line segment that you have entered via
TRACK
- the series of interaction points with the gas of the particle
that passes through the chamber
The two kinds of tracks coincide unless
- the particle has too little energy to reach the end-point of
the specified line segment
- the particle undergoes multiple scattering and deviates from
its original trajectory
In both cases, the track can be a point in some circonstances.
in that event, a marker is used rather than a line.
Polyline item: the tube enclosing the wires, the tube is
described with the TUBE statement.
Fill area item: Wires are, unless the
WIRE-MARKERS option is active,
plotted as areas to allow them to be picked in the
GRAPHICS-INPUT instruction.
Note that, by default, the wires are plotted as hollow
circles. This might give the false impression that this
is a polyline item.
If the WIRE-MARKERS option is active, then wires are shown
using C-WIRES,
OTHER-WIRES,
P-WIRES or
S-WIRES as
appropriate.
