This section details how points are assigned colors and symbols.
- Colors for Trajectories:
- Trajectories (and multiple trajectories)
have both an alternating
color and a pick color. The pick color can be chosen by the user
using the Color window. The alternating color is automatically
the next (non-system) color in the colormap.
Each trajectory of a
flow object is colored using the same alternating and pick colors.
The default symbol (shown in the Defaults window) is always assigned.
- Colors for fixed points:
- The DsTool convention for hyperbolic fixed points is:
saddle points are marked as green crosses, sinks are
blue triangles, and sources are red squares. In each case, the alternating
color is negative, and the pick color and symbol code are the appropriate
integers.
Hyperbolic fixed points that are found by the Fixed Points window always
follow the convention. Hyperbolic equilibrium points that are
found by the Equilibrium Continuation window may or may not be colored
according to the convention, depending upon the value of the Monitor
Switch setting.
In either setting, the equilibrium points are assigned dots, save those found
by the ``Search'' operation, which are assigned triangles.
- Colors for periodic orbits:
- Periodic orbits are colored using the DsTool
convention: attracting periodic orbits are colored blue, repelling periodic orbits
are colored red, and saddle periodic orbits are colored green. Periodic orbits
are always assigned dots.
- Colors for bifurcation points:
- Bifurcation points found by the Equilibrium
Continuation window will be colored according
to the colors in the Continuation Colors window.
Saddle node bifurcation points are colored green. Hopf bifurcation
points, degenerate Hopf points, and resonant saddle node points are colored
using the last three colors in the colormap, which can
be changed by the user. In the default
colormap, the corresponding colors are magenta, orange, and
sea green, respectively.
Bifurcation points are always assigned dots, save those found by the ``Search''
operation, which are assigned triangles.
- Colors for selected points:
- Points which are saved from the Selected Point
window are assigned the pick color designated by the Color window, negative alternating
color, and the default symbol.
