But given what you already have it should be trivial for you to make it do what I want

Well, no. I don't think this does what i'd like. It allows rotation around axes that I don't care about. I'd like an x/y plane and I'd like to be able to do free rotation around an arbitrary point like, oh, the origin.

OK... Like that, perhaps. There are some unfortunate zoom effects in the demo - if I grab to rotate it always also zooms in or out. Have hints on how to still have zoom and also have rotate?

I'm able to rotate about the origin 90 degrees at a time easily enough. Are there any tools to allow free rotation around some origin? I'm not finding anything!

Or, if I use a 3d graph but constrain it to 2d will this allow free rotation?

thx

Thanks Christopher. We'll keep these things in mind as we go forwards.

So I have to ship. So what I did was to make the background of the Tchart a dark color and then I hide the frame. This is suboptimal but, hey, well, it does work, I suppose. And it performs.

Although, hey, that doesn't help things work.

So, a full circle dial does work but they don't with limit stops? That doesn't really make sense to me. Ah well.

Looks like gauge.Frame.circled is really bad on performance and it doesn't appear to affect the end visual result - in this case.

Well, in theory the .NET WPF is rendering using DirectX, no? And this is, in fact, born out by that project. If you close the Forms window and open several more WPF windows and then do the performance profiling again you will see radically different results. The WPF forms render much faster. Still, ...

Thx. I'll upload something I suppose :) My feeling right this second is that implementing this (fully) in WPF will probably help. Kind of a bummer, really, since it already all exists. Hopefully that will render using the video card and not the CPU. I guess I'll do a few tests to make sure things wo...

How do we set up double/triple buffering? Any benefit to doing so? Or, can I push the processing of each gauge to a different thread (nope!) [/i]? To the video card? Assuming I'm showing 2 copies of each gauge (that's just life) can I do magic and draw each just once but show it twice (albeit, alas,...

(And... I'd rather not post my code, actually. As I'm perusing the forum right now I see that GoogleBot is as well. Sigh...)

I've made a user control that represents the gauge I'd like to use. When I make, say, 10 instances of this control and attempt to update them every .4 seconds then systems.windows.forms.ni.dll uses 94% of my computer's CPU and only the form that has focus will actually update. If you prefer, it's st...
