DPlot

That was just enough info to get me going. I did a google search on "matlab XTYP_REQUEST" and found an example (from among ALL 3 matches returned) that used the command 'ddereq', and this does the job. Thanks, Chris

Hi David, I notice that the latest version has dde commands MaxCurves and MaxPoints - Thanks! But how do I use them? Here's how I get on with Matlab: h = ddeinit('DPlot','System'); rc = ddeexec(h,'[SelectCurve(2)]'); ...and I have tried, for example: curves = ddeexec(h,'MaxCurves'); but this throws ...

Hi David, Just a few minor suggestions regarding the macro editor. first, it would be great if you could open up a macro from within the editor. As it stands, you have to save, close, then start over with the file menu. Also (very minor), it took me a while to find out how to assign keystrokes to ma...

The problem I am experiencing with dplotlib.dll stems from my lack of knowledge. Matlab requires a header file for the dll, and I don't know what it is supposed to look like. >> loadlibrary('c:\work\dplotlib.dll','c:\work\dplot.h') Warning: The data type 'error' used by function DPlot_Command does n...

Hi David, Is there a command to tell me how many curves are already allocated with dde? For example, if I use filearrays to create 2 curves, and then I want to add a new curve at a later time, I would like to be able to obtain maxc (and maxp for that matter) so I can add to that number without havin...

Here's what I get in Matlab: >> loadlibrary('c:\work\dplotlib.dll','c:\work\dplot.h') Warning: The data type 'error' used by function DPlot_Command does not exist (Type "warning off MATLAB:loadlibrary:typenotfound" to suppress this warning.) Warning: The data type 'error' used by function ...

Hi David, I have been doing some research on Matlab and external dlls. it can do it, but it needs a header file containing function prototypes to be able to load the library. I tried using 'dplot.h', which I found in the dplotjr\dplotlib\c directory, but it didn't work. Any suggestions? Thanks. -Chris

Cancel that request. I forgot about the sprintf command in Matlab.

Hi, I am creating plots using Matlab and DDE. Works like a charm. I am using the XYXY command to pass data to be plotted. Matlab's extensive use of arrays and matrices makes me wonder. How hard would it be to have a command that would allow me to pass arrays of data, instead of X,Y pairs? Perhaps th...

Any idea how I can send data to DPlot from Matlab? -C-B

Minor suggestion: How about making the save as dialog more like, say, PhotoShop, where the file type pull-down determines the format? The window with all the radio buttons is getting crowded and is a bit non-standard.

Hi, I love the get/set preferences option. What I do is use a text editor to go in and delete the variables that I don't want applied. For example, the axis ranges may be different for two plots, but I want the formatting to be the same. One nice feature would be the ability to update preferences in...
