3D graph slow drawing

[elset191]

Is this sufficient?

hello elset, unfortunatelly it is not. I really need to see the lines. But thanks anyway

I shut of auto-scale on all axis and tossed the code that removes and creates all of the plots.

With those changes your example completes in less than a second and there is no jumping around.

2 C. Minnella:sorry but it still causes not really appreciated/expected behaviour for the user

2Ben:May I ask you for the code Ben? Since I do not see difference here, thanks

[Ben]

Not usre if I saved this before shutting down that machine. I'll look again in the AM to see if you had trouble with this.

Hi Ben, the problem is that I always have to erase and recreate the plots since I do not know their amount in advance -> therefore I still see the process of drawing.

[Ben]

Have you tried adding more than enough plots but leaving the extra empty?

If you want to wipe out all of the old plots and re-do them every time....

Then you lanch a dialog screen saying "Now updating plots! The may take some time, so please wait".

It your call. Have fun!

This is kinda lame, but you could place a picture of the graph in front of the graph while it is updating. I ran into this problem once, I and used a tab control where the graph tab wasn't visible while updating. A much better solution is to just use a different graph control. I'm not sure exactly what you are going for, but I've mentioned ZedGraph a bunch of times here. It's free, and produces very nice looking graphs. Also, since the 3D graph control is just an activeX object, ZedGraph isn't much harder to implement.

2C. Minnella: Thanks for the info. I might give a try to that in my next project!

2Ben: I will try that, it is not sucha bad idea 🙂

After playing with the new 3D graphs and realizing how buggy they are I reverted back to the ActiveX graphs and found a workaround for the slow drawing of multiple lines when the defer panel updates doesn't work. Maybe somebody will find it useful.
