How to generate a time-history plot

So called time history plots can be created based on a previous displayed sequence of data-sets (see ``Toggle Dataset Sequence'') with the command ``graph''. Sometimes the user wants to avoid the animation. This can be done if the required entity was selected before the sequence of datasets were selected. Do not select the entity then but use the graph command instead. It is also possible to use only the command line. For example:

- lc 1 e 3
- lc 1 2 10
- graph set t

will produce a time history plot for the nodes stored in set over all loadcases from 1 to 10 for the entity nr 3.

In case you need nodal-values along a sequence of nodes (i.e. stress vs. x-axis) you might use the ``prnt'' command. Then you grap the information from the xterm with the mouse-pointer and store it in a file with the help of an editor. The contents of that file could be displayed with gnuplot. Or you use the file ``graph.out2'' which stores the node-number and the node-coordinates and all values at this node-position for all datasets. This file is also generated by the ``graph'' command.
