This interface is used to control all open XY-Plot windows and files. External XY data can be loaded for plotting and/or cross plotting.
Often there is need to plot force vs. deflection response of structures. This requires a force vs. time curve and a deflection vs. time curve. Cross plotting allows users to select deflection from the deflection vs. time curve for the x-axis and force from the force vs. time curve for the y-axis. If the number of points for the 2 curves is not the same, the data is interpolated.
Cross plotting can also be done from plot read in by using the Add button or from XY-plot windows. For cross plotting data from XY-plot windows, the Window option should be activated (The default is the File option).
The format of external XY data can be in Microsoft CSV format or XY data pairs as shown below. In this example, note how the first line of each curve definition defines the number of XY data pairs that follow:
20.0,0.0
10.0,20.0
4
0.0,0.0
30.0,20.0
40.0,10.0
50,0,10.0
Show: Show selected plots.
Cross: Cross selected plots.
Sample1: A sample to show how to plot curves.
Sample2:A sample to show how to cross curves.
