The *History XY Plot* tool is an extension to
baspl++ offering a set of standard
computational mechanics xy data extraction and graph
visualization, such as graphs displaying non-linear solid
mechanics behaviour. The
*History XY Plot* tool is targeted at supporting
B2000++ model databases, and It
can be operated interactively or with scripts, which can be
generated automatically from interactive
sessions. The *History XY Plot* tool works seamlessly
with all other baspl++ viewing
functions. An example of a typical non-linear solid
mechanics load history plot is given below.

The *History XY Plot* tool is based on
a B2000++ specific data
extraction, creating pairs of (x, y) values to be rendered
with the baspl++ * Graph * and
* Curve * classes. Data extraction functions of the
x- and y-columns of data currently include

- Reaction forces
- Sampling points of specific elements
- Degrees of freedom of specific nodes
- Distance between 2 deformed nodes
- Attributes and cycles

The extraction functions can be applied to the x- or to the
y-axis (columns). An example of a typical non-linear solid
mechanics load history plot is given below, where the data
extraction function for the x-axis is the attribute *TIME*,
and for the y-axis the sum of the forces induced by the
compression of a cylindrical composite panel.
