DPlot

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 ...

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 ...

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:
[ContourLegend(1)][Contour3D(0)][ContourMethod(0)][ContourLevels(32,0,0)][ContourColorScheme(2)][ContourCustomColors(16711680,16776960,65280,65535,255 ...

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 ...

On the "Always start maximized" issue, now that I have the GenerateMesh problem worked around, it seems to be okay. If it's set to maximize, there's some flashing in the background, but everything ends up okay. When I had both issues going on is when the problem looped up. I'm running V1.0.5.5 and ...

I used to use AppHide right after I started DPlot (without checking the previous use status), but that seemed arrogant of me if they had it running before my app! When I removed the AppHide, I ran into trouble if the user had the general option set to "Always start maximized" (threw me into a redraw ...

Thanks for the Windows API calls help. I'll try that.

The testcase I'm trying has a 15x9 grid and I'm using an np=4 on the GenerateMesh command. It looks like the extents grow by about 15% on this case. I'll be watching for your GenerateMesh "option", but I'll get around it in the meantime. Thanks ...

Sorry about not being specific! My code is just trapping a returned HBITMAP of NULL, so I really didn't even know what kind of error. I have since recompiled and added a call with DPlot_SetErrorMethod(2). Now I see a pop-up window that says "DPLOTLIB, Timeout error, current timeout value=20000 msec ...

I'm using a GenerateMesh command through DDE with the DPlot_PlotBitmap call. If DPlot is minimized (as is the default when it wasn't previously running), it's giving me an error, but if I have DPlot maximized (as a window behind my app), it works fine. Am I missing something? I've tried hard to have ...

Thanks for your quick responses, as usual! I'll use the temporary solution and wait for the next release for the complete fix.

I'm producing contour plot "slices" of a single plane from a 3D space through DDE. I send over only the data for the plane I wish to see at the time. Sometimes, the triplets of the plane I send to DPlot have no variation in the Z value. I send ManualScale and CustomColors commands that deal with the ...

I know I've seen this in documentation somewhere, but can't find it now...How do I force the use of DPlotJr from a DDE use (to simulate my clients state) while I have both DPlot and DPlotJr on my computer?

Thanks! The [ClearEditFlag()] option works for my application.

I'm using DDE (DPlot_PlotToRect) from C++ and doing some simple line plots. If I change the ManualScale values and call again for a new plot, then when I exit, I get the "Plot1 has Changed. Do you want to save the changes in a DPLOT file?" box. I do my own DPlot_Start and conditonal DPlot_Stop if ...

I added an OnSetCursor member to my view, put a CWaitCursor in there and it took care of the problem. I have a CWaitCursor in the routine that calls DPlot, but I think the WinProc function envokes a new WM_SETCURSOR when calling DPlot (I guess replacing the current cursor back to the default ...

I'm using DDE from C++ to get a bitmap of a contour plot represented by a large number of XYZ points. Because of it's size, there is a few seconds delay while the plot is generated and the bitmap returned. I've tried every trick I know on the C++ side to set an hourglass wait cursor to fill this ...
