Setting the general characteristics of a plot
The plot configuration dialog is displayed whenever one creates a
plot, and when one pulls down the Configure menu of a plot, and
selects "Modify Plot". This dialog allows the title
of the plot to be specified, the x-axis to be configured, and the
specification of plotting attributes. The fields are as follows:
- Plot title
Use this to set the title of the plot. This title is displayed
within the plot itself, and is also used as the X-window title of
the window both when visible and when iconized.
- Register
This is the register who's value is to be plotted along the
X-axis. It should be a single element register specification.
- Label
This is the label to draw under the x-axis.
- xmin
This is the value to give the left end of the x-axis. This
should be zero when scrolling is enabled.
- xmax
This is the value to give the right end of the x-axis.
When scrolling is enabled, this specifies the length of
the x-axis.
- Scroll margin
When the plot scrolls, a margin of this amount is left
in the direction in which the data is moving along the
x-axis. This ensures that the plot only has to scroll
every so often. The margin is specified as a percentage
of the width of the x-axis.
- Scrolling mode
This specifies whether and in which direction to scroll. The
possible values are:
- maximum
Scroll whenever data falls beyond the right edge of the
plot.
- minimum
Scroll whenever data falls beyond the left edge of the
plot.
- disabled
Don't scroll at all. The x-axis will have exactly the
limits specified by xmin and xmax.
- Marker size
This specifies how wide the plotted dots and lines appear, in
multiples of 0.005 inches. Note that the limited resolution of
Sun displays means that one has to increase the width to 6 before
any change is seen compared to a width of 1. This is not the case
on modern printers, so the result is that a given width
specification may look different when displaying on the screen
than on a printer.
- Draw lines between points
With this button depressed, lines are drawn between points that
were recorded sequentially in time by the real-time system.
