Vista 2.0 allows greater degree of flexibility with the presentation of the
plot axes than was present in version 1.0. These can now be tailored to
suit individual specifications. The text fields permit the editing of the X/Y limits
and the X/Y bin sizes.
The Define Limits check box disables/enables the X/Y limits text fields.
With Define Limits off, the text fields are greyed out, preventing any text input.
Attempts to type will be unsuccessful.
The bin values are only relevant for the colour density, numerical density,
contour and histogram plots. The bin text fields are greyed out for other modes.
Changing the bin values can have a profound effect on the visual appearance
of a plot and experimentation with this option to find the most representative
plot is recommended.
- toggles the plot grid on/off.
- Square Axes
- ensures that both the X and Y axis lengths are the same.
This forces the layout of the plot to change in order to accommodate the new
graph shape. The plot summary is positioned to the right of the plot and the
figures are listed vertically in one column. With Square Axes off, the plot
becomes rectangular with the width maximized. The plot summary is
positioned beneath the plot in a fashion similar to the plot output from Vista 1.0.
- Show Axes
- toggles the axes on/off for the plot.
- Show Ticks
- toggles the axial markers on/off
- Show Numbering
- toggles the axial numbering schemes (labels) on/off.
In version 1.0, the title and axial labels were set by default. The pop-up menu
available in Vista 2.0 allows the user to change the default expressions and create
their own plot labels. The check boxes for each text item can be used to dictate
whether or not a text item appears on plot.

- the default title "Y vs X" is generated automatically.
Should the title be suppressed, the Y axis will generally lengthen, as there is
free space where the title was.
- X/Y axis
- up to 20 characters are permitted for the axial labels. Disabling
either of these labels will not change the plot dimensions.
- this is the plot statistics summary.The min., max, mean, mean sd etc. are
- listed in the Analysis Summary. As mentioned in
the position of the summary is dependent on the plot shape. If the Square Axes
option is disabled and the Analysis Summary option is also disabled, the plot will
expand to fill the free space.
- Text Size
- as with the spreadsheet, the text size used for annotation can
be redefined. Values from 10 to 150 pixels are currently permitted. The size of the
text can have a profound effect on the plot dimensions, as everything is scaled
relative to the Text Size.
