vertical spike chart

[josh]

Maybe I'm just not thinking clearly, but....

Is there an easy way to do a spike chart? Say you have a graph of frequency versus dB energy of the radio stations in your home town. Now, you don't want to have to set a y-value for every frequency on the radio, you just want to plot certain hits...but the catch is you don't want a line graph doing connect-the-dots nf the y-values. You want every frequency that is a "hit" to spike up and all the other frequencies to have no y-value.

A bar graph maybe? David, any thoughts?

clarification...

x-axis is frequency and y-value is dB

spelling mistake above: "connect-the-dots with the y-values"
