The stacked XY chart displays the priorities for the selected
view and all criteria. This chart displays only three dimensions,
but you can visualize the contributions of all criteria. Because this
is a complex chart, you must select and clear the check boxes in the
criteria list carefully.
The
connector feature
If you display a stacked bar chart, you can select which
criteria to include in the chart. The black triangles indicate the
total score for each element. Then, if you display a stacked XY chart
and select the same criteria for the X axis as you did for the stacked
bar chart, the element check boxes have the same positions on the
X axis as the black triangles had in the stacked bar chart. This means
that the element check boxes can be both on the right and the left
of the Y axis.
The elements positions on the Y axis are calculated
the same way as the positions are for the X axis. If the same set
of criteria is selected both for the X and the Y axes, elements to
the left of the Y axis are located below the X axis, and elements
to the right of the Y axis are located above the X axis.

If you select a Connector attribute, all
of the elements with the same value for the attribute are connected
with lines. In the image below, the requirements that were changed
last by the same person are connected with a line.

Criteria priorities
When stacked bar charts
and stacked XY charts are displayed, you can take criteria priorities
into account. To understand how criteria priorities affect charts,
see “Using criteria priorities in charts.” To use criteria priorities
in charts, follow the steps in the topics in the “Configuring criteria”
section.
