2. Plot

In Vista version 1.0 there were separate plotting menus for histograms, scattergrams and for PCA plots. Version 2.0 has only one plot menu. However, depending on the type of plot being created, certain buttons may be greyed out or will activate specific pop-ups.

The plot window display is split into two parts. The main feature is the plot itself, but also present is an analysis summary for each of the parameters chosen for the plot. The title of the plot relates to the parameters selected. In the case of a scattergram the title is by default Y versus X.

As in version 1.0 the plot presented in Vista 2.0 is an active plot. Data points can be selected by clicking on them. Selected data points are coloured red. Plot objects can be de-selected by clicking on them again.

Picking an active plot object will add the associated refcodes to the refcode scrolling list. These refcodes will initially be highlighted in this list. Refcodes in the list can be de-selected by clicking on them. This does not remove the refcode from the list and does not de-select the active plot object. All refcodes highlighted in the scrolling refcode list can be viewed using the ASER Viewer (as described in section 3) by selecting View Refcodes.

As new plot objects are selected the relevant refcodes are appended to the refcode scrolling list. This list is not alphabetical. The last refcode in the list always refers to the last data object selected.

Operations can be carried out on the plot using the plot function keys located to the right and to the bottom of the window. Full descriptions of the actions available with these buttons will follow.
