DPlot

Thanks for your quick reply!

Your solution (Operate on X and Operate on Y) worked just fine.

Could this behavior be made into a 'check box' option on the 'Polar Options' dialog though?

Since ...

Hello,

I ran into a situation where I have a polar equation which can generate negative radius (Y) values for some ranges of angle (X).

Can you add an option on the Linear/Log Scaling | L. Polar ...

David,

I tried to reproduce the crash with several of the same data files I plotted during development of 'split' but have not been able to recreate it.
I'm can't remember if I used the first spli ...

David, thanks for advice on how to do this!

Please note that my initial post shows incorrect equation for Z:
Z = 1+2.0*sin(75*t).

The equation accompanying David's reply with my example plot ha ...

Yes, I see the same cutoff help text for the "Split at Y=" (and I too am using WinXP). I also was able to crash DPlot (in the form of silent close of application) by selecting one of my two ...

I just discovered that when a note is newly created it may be hidden by the legend box if the latter is located in the upper-left corner of the graph window.

Even though I now know to look there, i ...

I tested your method and got the desired result - illusion of a single curve which cleanly makes the color transition(s) with no artifact lines (the false condition value plotted as a 'flatline')

R ...

Here's a suggestion for a new feature: Provide ability to define a Y-value threshold for a curve below which one color is plotted and above which another color is plotted.

A colleague of mine for w ...

Duh! (I slap my own head)

Sorry I didn't read your earlier posting closely enough.
When you wrote, "Options>Extents/Intervals/Size your Z extents", my mind was still focused on Option ...

Do you have any plans to extend 3D capabilities to allow representing 3D parametric equations?

Also, like 2D polar coordinates, in conjunction with 3D it would be nice to be able to represent equat ...

I've sent a zipped file containing the .grf file and the .set configuration file I used.

Hello,

I just noticed in the latest version (2.2.9.4) that when one attempts to either Center or Right justify text in a VERTICALLY oriented note box that the text will get redrawn outside of the b ...

Hello,

I'm running the latest version (2.2.9.4) of DPlot.
I imported a 3-column CSV formated file (X,Y,Z) ["K" Type File] and discovered that the contour color is not working properly fo ...

OK, I updated my e-mail address. You've had my proper address for update notices so it didn't occur to me that the forum profile held a separate one.
(That shows how long since I last used this forum ...

Hello.

While doing some math exercises out of a book, I got a chance to use the 3D ability of DPlot (nice to be able to do rotations with CTRL-arrow keys!)

I noticed that the axes are drawn as & ...

Whoops- When I looked at the help and briefly scanned the list of available functions, I must have unconsciously breezed past "rnd(x)" thinking it meant "ROUND"

Thanks again!

Hello David,

I would like to use DPlot to create a graphic file to imbed in a document which illustrates a digitally sampled "noisy" sinewave. However, I noticed that DPlot does not provide a "rand ...

I guess I should get familiar with the macro commands. My request in another post to have DPlot window "stay on top" was already in your macro list! Embarassed

Ray D.

I like the $X and $Y thing!
Now that I have 20/20 hindsight, I did some searching for these in Help but they did not show up -- What other "hidden" format specifiers do you have available? I could ...

David,

On the "File" pull-down menu, when one inadvertently selects a "most recent" DPlot file which is no longer available, could you provide an option to delete the shortcut link when the pop-up ...

David,

I am now using Add/Edit Note and Point Labels quite a bit and noticed that Notes are not saved with a custom setttings (.set) file.

In my application, I basically add the same 4-line note ...

David,

I've got a couple of suggestions to improve working with Polar Plots:

Idea

Point Labels:
Currently, only the magnitude value can be shown. It would be nice to have the magnitude/angl ...

David,

I don't know why I just noticed it now, but I see that linked list information is not stored with the DPlot file. When I re-open a file, my links are gone. When saving a DPlot file, could yo ...

David,

It would be a nice convenience feature to have the option of keeping DPlot's Window visible ("On Top") when I changing the focus to another application (Microsoft Excel, in my case).

This ...

OK, that did it.

Thanks Again. Very Happy

Ray D.

You could start at 47 and go around the circle to 407 (and repeat as needed)

I missed the obvious. Thanks for pointing this out.

OK, so this isn't so bad for me (only 8 data points per curve). I ...

Thanks.

Another improvement idea "hit me" while working some more with the Insert Link Dialog:

I just finished a sheet in Excel which I can use as a template for analysis sets of test data. I ju ...

David,

I am using v1.9.2.2

The example I e-mailed to you has two labelled data points. One box with "0.21" whose data point is at about 100 degrees, and one box with "0.177" whose data point is ...

David,

I wanted to take the difference between two loosely circular enclosed Polar Chart regions ("curves") generated from discrete data points (linked from an Excel Spreadsheet). I got the followi ...

David,

Thanks for the changes to DDE/Insert Links thus far.
However, I found that the Insert Link dialog's "Recently Used Links" list can get kind of "cluttered" fairly quickly when one is develop ...
