An 窶彜-curve窶 is a graph with the cumulative observed frequency along the Y-axis as a function of the output values along the X-axis. That is, for a given value on the X-axis, the corresponding value on the Y-axis is equal to the observed frequency of output values less than or equal to the chosen value on the X-axis. The S-curve is an estimate of the cumulative probability distribution function of the output value.
If the frontmost window is a main document window for a simulation data file, the 窶彜-curve窶 command produces S-curve plots for all selected data nodes.
If the frontmost window is a 窶徭imple plot窶 window created by using the 窶彜-curve窶 command, this menu item is disabled. In this case the window title is of the form:
<node>.s
where <node> is the name of the node whose S-curve is plotted.
If the frontmost window is a 窶徭imple plot窶 window created by using either the 窶廬nverse S-curve窶 command or the 窶廩istogram窶 command, this menu item is changed to either 窶廩ide S-curve窶 or 窶彜how S-curve窶 depending on the state of the window. If the plot already contains an S-curve, you can use the 窶廩ide S-curve窶 command to hide this curve. On the other hand, if the plot does not contain an S-curve, then you can use the 窶彜how S-curve窶 command to show it.
