Can anyone share some code (C#) or at least explain the process for displaying a waterfall using FlexAPI?

    That’s an excellent write up. It begs the question, why is the waterfall data so complex? Why couldn’t the same data that generates the panadapter be applied to a gradient and plotted?

    Mark,

    I’ve wondered the same thing but don’t have a good answer for you. If you want to look at code, take a look at my GitHub repo for xSDR6000 (the v3 branch is the latest). It’s a SmartSDR-like client for use on the Mac (i.e. Apple Mac). My implementation of a waterfall is there. The code is in Swift but probably readable by a C# programmer. It uses Apple’s graphics approach (Metal) but again, probably pretty readable.

    I figured the reasoning was something like what you said. Thanks for the explanation.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
