> The first entry is a frequency ex 1.8 MHz
> The other values are SWR[13.8], Resistance[34], Reactance[134].
> I want to plot the last three values on three line graphs in different colors using the first value [freq] at the bottom [as the dependent].
> As you can see the freq goes from 1.8 to 54 Mhz.
