we've been using Pro Essentials graph (gigasoft.com) but it doesn't play nicely with delphi so it's been causing problems.
we need to display waveforms and bar graphs (not at the same time). the waveforms could have thousands of points. we need something pretty full-featured that's a "living" product.
our app is a native win32 delphi 2009 app.
thank you for your suggestions!
