Origin Version (Select Help-->About Origin): Origin 7.5
Operating System: windows NT
I have tried without success to find a software that include interactive 3D scatter chart. My 3D chart contains different clouds of points and I want to select them individually (it should highlight the specific data in the data file) for more indepth statistical studies. Is it possible with Origin or with an other software?

Hi Kropcheck,
This capability does not exist currently in Origin. We are however interested in learning more on what you wish to do. When you select an individual point, do you just want the corresponding row of the worksheet to be highlighted? Or is there more to this?
Thanks,

Hi Easwar,

Firstly, I want to select more than one point at the same time (e.g.: high density of point in one part of the chart). Then the selected points should appear on the data sheet with a special sign that give them the capability to be used separately from the rest of the data.
With Origin, I think that you are very close of this kind of functionality because on a 3D chart it is only possible to select one point at the same time with a pop-up window of the respective XYZ coordinates.

Here is an example that marks individual points:
Add a fourth column of data to your XYZ worksheet (assume it's Data1_D).
Fill the column with 1.
Set the color of your 3D Scatter Graph to use column D as the color Index.
Use this script with your graph active:
dotool 3;
def pointproc {
data1_D[index] = 2;
}
As you select each point you wish to mark, double-click or press Enter and its color will change to red. When you are done, press Esc key or click the Pointer tool.
Column D will have the value 2 for each of the points you marked.
(This is similar to way masking works for 2D plots.)
Your idea of marking a region would require a different tool. I would take the approach of viewing 2D projections of your 3D data and using some kind of 'smart' rectangle to mark data points within the rectangle. This may be more work than you are willing or able to do.
