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 ...

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 ...

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 ...

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 ...

Here's what I get in Matlab:

(Type "warning off MATLAB:loadlibrary:typenotfound" to suppress this warning.)

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 ...

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 ...

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 ...
