How to use the csvstream device

[polygon]

I've been looking into plotting some data that comes from a microcontroller via Ethernet. I built a translation layer that converts this data into the format understood by csvstream. When adding the device, data reception seems to work, I get the hardware inputs in the Filter Graph and when I hover over them I see the last received value in the tooltip and all that seems to look fine.

The issue I have is with the plotting, as the documentation mentions:

It is primarily intended for extracting low rate I2C sensor readings and ADC values from an embedded DUT, so that that these values may be plotted alongside multimeter/power supply readings or other data coming from more conventional instrumentation. 

Adding the device does not create waveform views, I cannot seem to Drag & Drop the channels to the Waveform view. The issue seems to be that the CSVStream device has STREAM_TYPE_ANALOG_SCALAR which don't seem to be plottable, yet the documentation above mentions plotting.

Is there an example on how to make this work or am I misunderstanding what this device can do?

You're probably looking for the Trend filter graph block, which takes in a scalar and outputs a live-scrolling "strip recorder" waveform plotting the scalar over time. It defaults to a 10K point max record length which is a little short but you can change the limit in the filter properties.
