I fundamentally do not understand how to enter 3D data

[Keith Ryan]

I have many CSV files with 3D data that I need to make contour plots. I am trying to do this with Statistica Academic version 13 on Windows 10 Student.

I must have a profound misunderstanding on how to copy or manually enter data for 3D data. I 'get' that you are supposed to have each column header be the variables. What I do not understand is how you enter the Z data. I have attached a sample 3D data set entered into excel. The color is not important to the data, I just did that to make it clear what axis I am refering to.

Can someone help me on this conceptual basis I have searched online and looked at the manual, but this is so a basic issue that I am having that it doesn't seem like anyone has considered it.

Heck, I do not even see "Statistica" listed as a Product down below. I'm completely lost!

Hello,

You're right, statistica expects data to be in row/column format. But you can still import your data as is and transform it as required.

I ran a simple import based on the sample you attached.

1. Import data as is with X coordinates as the column names

2. Use stack operator (Data>Stack>Stack)

3. Use Variables as all X axis columns (i.e. all but the first column)

4. And stack the data based on 1st column (i.e Y axis)

5. You should have 3 columns for the respective 3 coordinate axes
