V2.0.5.7 and DDE non-variant random 3D plots

[meany]

David,
I tried the new version release V2.0.5.7, passed over a non-variant random 3D dataset through DDE and I'm still having troubles. It pops a timeout error box quickly, maximizes the hidden DPlot, and returns a NULL HBITMAP on my DPlot_PlotBitmap call. I can see non-variant data if I go through DPlot directly now, but does it work through DDE? It might be some other combination of the commands I send for the ManualScale or something, but I don't know what else to try. (On the ManualScale, I tried Z hi and low extents equal to the single value, and I tried them expanded around the single value.) I can send you the command string and the data if you'd like. Sorry, my data is a pain![/img]

Charlotte,
(After a momentary panic thinking I might have broken everything ), the demo programs work fine, at least here. I just tried the C example with 100,000 random points and producing those 100K points, sending them to DPlot and retrieving a bitmap took about 3 seconds. So I don't know what might be going wrong in your case. You're of course welcome to send me whatever you have and I'll take a look as soon as possible.

Glad yours works! Wish mine did! Maybe I broke everything! Were all your Z-values non-variant? This example has them all zero.

Here's my commands:

It will be late tonight before I have a chance to dive into this, but I'm curious about what you're up to? Since you can't programmatically edit the Z values of a data point, what's the point of all those 0's?

[meany]

I have a 3D space that I slice and dice into X, Y, or Z planes and let my user see your shaded band contour plots for individual planes in that space. It happens that some planes have non-variant data. My application allows different views into that data. They can also opt for line plots where two planes intersect and I send DPlot the points for those lines. My C++ application has OpenGL 3D views that animate through the space in addition to the DPlot plots.

I tried sending the Z extent hi and low for the entire space, not just the plane, but still had the same error (ie, I sent [ManualScale(10.16,-40.64,154.94,40.64,-3.75573,15.0682)]).

[meany]

I didn't say this in my previous post, but my 3D space (cartesian coord. system) is filled with a parameter of interest--a fourth dimension, per se. By the time I send data to DPlot, the "X" and "Y" values are two of the cartesian values (reducing the data to a single plane), and the "Z" value of the contour plot is the fourth dimension. Does that make sense now?

[DPlotAdmin]

Yes, thanks.

[DPlotAdmin]

I'm not sure what's going on yet, but your example will work fine with [ContourMethod(1)] (contour lines). I'll fix this as soon as possible.
