Terminals of Different Types

[Tebefia]

Hello Folks:

Am having trouble to achieve my desrire on my code, and the Labview gives giving me a broken wire that am trying to connect two different data types.  Well, what am trying to do as shown on the attached snippet is that I pass my analog input One Channel through the Digital IIR FIlter VI, and used the Unbundle by Name function to extract the Magnitude and pass it along with a Numeric Control (Gain) as inputs to a Multiplier (because I just want to use that Numeric Control to control the amplitude/magnitude of the plotted signal on my waveform chart), but am getting the broken wire when I try to connect the output of the Multiplier to my Waveform Chart.

I would appreciate any suggestion to correct this.

Thanks in advance.

Folks, I forgot to attach the snippet earlier.  Here it is!

Open the context help window (CTRL+H) and put your mouse over the Waveform Chart.  It will tell you the data type that the Waveform Chart needs to function.  You must manipulate your data so that it is in the format that the Chart can accept.  The error you get from clicking the broken arrow will tell you the data type of the source, and the sink, and how they are incompatible.
