How to display a time series

A time series can be displayed with the qcl procedure pl_time.qcl. The following example displays a time series mkn335_91a.time, which has only one spectral channel. Lines beginning with QCL_CL require input. Note that the minimum Y-axis value to be displayed defaults to 0.0, even if the actual minimum is negative or very large, and that this examples plots two windows, one each for the top- and mid-layer light curves. The default graphics device is xw (see table 5 for alternative device names).
