Newbee here. I'm trying to use the Ultimawaterfall activeX control in
a Visual Studio 2005 (Visual Basic) program to display a spectrogram.
My problem is with the horizontal scaling of the chart. I send the
control a 1024 point FFT that I've calculated using

Waterfall.Chart(mag)

It tries to generate the plot but will only show all of the data if
the chart's width property is set to 1024. I believe this means my
chart will be 1024 pixels wide - very large. Is is possible to scale
the chart to a smaller width and still show all the data? I'm not
quite sure how this is accomplished in the sample programs provided.

Thanks in advance for your help.

Ultimawaterfall's data width is 512 only. You can pre-scale the data array before feeding it to ultimawaterfall...
