DPlot

Hi David, It has not been an issue in the past 16 years, but I just noticed the Evisive 3D importer plugin doesn't populate the Z-axis text from the .evd binary file. (It's entirely possible that I have the binary file formatted improperly, but not badly enough to break anything else) I don't have t...

Perfect!
So Y2Axis is a recognized keyword, even though the graph type doesn't use it.
Thanks!

David, Since .grf files are ASCII text, can I store/insert my own notes into a .grf file? As a test, I copied Z-axis text from a contour plot .grf and pasted the 'Y2Axis' and following title text line into a 1D line scan .grf before the 'STOP' line, and it didn't seem to adversely affect it. Are the...

I am trying to get the "FileName" of the Active DPLOT document in a VBScript. Am I correct that using the DPLOTLIB.DLL is not supported in VBSCRIPT?

Is there a DDE method? I have not had any luck in simulating this in Excel through DDE.

Any idea why doesn't appear to return values for VAR_A or VAR_B - only VAR_C?

This is the macro I am using. I am using # as a separator character to make file name parsing easier in wscript. The commented out FileSaveAs line doesn't give an error, but generates a bitmap with filename only - no title2 or xaxistitle. 'ImageConvert 'When calling from command line use: ' evimage....

I have a wscript calling a macro that is returning the following error from a ForFilesIn loop when it tries to process a file without Title2. NULL result for replaceable parameter |TITLE2| in FileSaveAs . Once I hit OK, the following box pops up. Negative acknowledgement received from server . I pre...

Does this apply to DPLOT itself, as well as DPLOT JR?

On a Windows 10 Home machine, DPLOT was installed and registered using an account with administrator permissions. In a different user account with less permissions on same computer, DPLOT says it isn't registered.

Hi David,
I am experiencing the identical issue with FileNewEx and file Save As. I am also generating XY plots via dplotlib.dll.

Any solution or workaround?

Thanks

I'm now using a simpler solution using the 3D surface plot for my application. The visual effect is better than Scatter plot anyway. I am only updating once every few seconds. DPlot has plenty of time to re-triangulate before getting the next data set. I do not need the sub-second updating of the pl...

Whether you're adding one point or 100,0000, the entire surface must be triangulated again, and triangulation is the biggest bottleneck That was my reason to try the Scatter plot. I am turning off Anti-aliasing, and deferring MinMaxCheck In my polling application, I am getting about 15 data points ...

In my VB6 application sending data to the 3D Scatter plot gives me timeout errors quicker than when sending data to a 3D Surface plot. It appears I can eliminate the timeout error sending to 3D surface plot by reducing how often I send data. Is the timeout error related to how often the addData call...

Thanks David.
I'll give it a try this week.

Hi David, Version 2.3.5.5 (27-Jan-2017) added settings for FileNew and FileNewEx commands to create an empty 3D scatter plot. I want to test that feature. A note on the page states: Green entries are programming issues, generally concerning DPLOTLIB.DLL.... Does this mean I could obtain this access ...

"bad" laptop installed enormous Windows update and it seems the problem has disappeared.

I've decided to declare success and run away.

I reproduced the issue by closing EVimage (dplot) with several plots open - without saving the plots. In Task Manager | Analyze Wait Chain, I get EVIMAGE.EXE is waiting for another process (splwow64.exe). I don't have printers installed, nor have I tried to print anything. The MS office 2016 is 32-b...

I'm having a similar issue with Windows 10 64-bit. I have two new supposedly identical GETAC S410 laptops with Windows 10 64-bit with the same version of dplot (evimage.exe ver 2.3.5.5). On one laptop closing dplot makes it go away, but still remains in task manager occasionally. On the other laptop...

Never mind.

I found a good example in C# ctest1 sample programs. I should be able to make it from here.

Thanks,
mike

My C is 25 years rusty, never learned much C++, and my C# understanding is non-existent.

I am getting an error

cannot convert from char[] to'System.Text.StringBuilder'

I'm Googling as fast as I can, but not finding the answer.

My c# code sends a to open a file in DPLOT.
How can I then retrieve the Title1 text? in my C# code?

Thanks David.
Any suggestions on masking the center of a circular shaded band plot?

attempting to use "delete thin triangles" on a fairly small data file in Shaded Band plot. Status of "Deleting thin triangles, pass 1" doesn't change. Cursor showing busy. Clicking on DPLOT title bar brings up "(Not Responding). Using Dplot version 2.3.5.5. Windows 7 32-bit ...

I took the easy way out. I am using the same XY plot code that already works well for me. The surface or scatter plot wasn't necessary for realtime feedback to the user - it was just flashy. Actually turns out the XY plot is better for user feedback during use. I'll keep the "busy" part in...

The return value from DPlot_AddData was 1 until DPLOT crashed, and it returned -16395 on the call that crashed it.
How do I know when its busy before it crashes?

Thanks, David. I just started with it. Creating a 3D scatter plot with FileNew(7) and the first several Dplot_AddData statements appear to work as expected, then DPLOT crashes and reopens full screen. It seems to do this after a random amount of iterations. Sometimes immediately - sometimes after se...

Using DPlot_Plot can I set up an empty plot with zero data points? If not, I suppose I can create a new plot with one data point at (0,0)? I have some confusion on DPLOT structure regarding maximum number of data points. Do you have a real-time example using scatter plot? Any language would suffice.

Hi David, I am currently streaming live data to a DPLOT windows to create a 3DR contour surface (shaded band). My code is somewhat based on example BTEST3. It works well, but as more data is added, the more time it takes to draw the surface. I think a simple solution for me is to just draw a scatter...

Normally I initially set up contour options on a shaded band plot (XYZ) just the way I like and save the default.set preferences. My application that sends data via the dll sends to a XY graph, then sets extents, and other parameters. I saved the default.set after the XY graph, which also saved the ...

When the command works, a new plot window is opened - I can see it appear/enlarge sometimes when it is slow enough, and then my applications starts sending data to it. When it doesn't work, the whole EvImage (DPLOT) application (main form) disappears for a split second before reappearing. I can see ...

DocNum = DPlot_Command(0, "[FileNew()]") has been performing flawlessly on several different computers running Windows 7 64-bit. On one computer I created a default.set file for the EvImage.exe (Evisive-branded DPLOT) and it seems to have broken this command. If I open a .GRF file first, t...
