wavescan plotting question

We are using IC5141. We ran a qpss simulation and put the following equation in the calculator,

dBm(spectralPower((DATA("/RFOUT_p" "qpss-fi.qpss")-DATA("/RFOUT_n" "qpss-fi.qpss"))/VAR("Rout") (DATA("/RFOUT_p" "qpss-fi.qpss")-DATA("/RFOUT_n" "qpss-fi.qpss")) ))

We get the plot appear to have correct values but instead of showing them as spectrum plot, it connects all data points as a continuous line. How can we get a spectrum plot with separated vertical lines? Thank you.

Also, what is the difference between qpss-fi and qpss.fd result?
