Goodmorning! :)
I am using OriginPro 8 and I am having some trouble doing a 3d plot.
I have experimental data of Intensity units vs width vs height.
I am trying to make a 3d plot, where x and y are width and height and z is intensity. I did convert the worksheet to matrix and then made the 3d plot using the matrix.
Although the shape turns out as expected, the scales are really messed up! The width scale is from -2 to +2, however on the 3d plot it is from -2 to 1 and also the center is also displayed wrong.
The height scale however is correct.
Any ideas why this is happening? I thank you in advance!! :)

Hi orillion909,
There is a set of options to specify the XY range of the mapped matrix. The default is the minimum and maximum of X (and Y) values in your data.
You notice the range is shown as pink dot lines in the preview.
Does it work?

Thank you very much for replying, but unfortunately it does not seem to work.I selected the range for y to be from -2 to 2 but it did not work. Also, i tried various ranges for y, for example -2 to 4, from -2 to 3 etc but the final 3d plot the y axis is the same as the first image I attached.
Do you have any other suggestions?
Thank you again.
EDIT: Maybe I should upload the worksheet? |

Hi orillion909,
I'm sorry for my misunderstanding above - the settings are provided to limit the input range of the data.
Although the expansion of the output range beyond the given minimum-maximum range may
behave "wildly", and may mislead the viewers (I mean like below), you can proceed the menu:
"Analysis: Mathematics: 2D Interpolate/Extrapolate"to expand (slightly!) the result matrix of gridding.

Thank you again for you immediate answer, I really appriciate!
This didn't work either :/
On the workbook to matrix conversion screen, the preview image is exaclty as I want it! I just can't figure out what I might be doing wrong.
Maybe I should upload the workbook file? |

Hi orillion909,
Not sure, but the max Y value in the preview seems around 1, though the Y axis scale is up to 2. Please check the maximum value of your original data. if the Y maximum is either around 1.0, or goes to 2.0. Is 2.095 (in your screenshot) the actual max of your data?
If your data indeed goes to >2.0, but you got such result, maybe you can send your Origin file to us (by clicking "Send File to Tech Support" link above).

The measurements on the Y axis are from -2 to 2..
I have sent the file to you and I hope maybe we can sort it out. |

Thank you, orillion909. I have received your file, and tried on my machine.
However, it worked okay as below. it worked fine on my Origin8.
So, now I suspect that your build of Origin 8 is old, and had a bug (then fixed).
My build(Service Release is the latest SR6), and if yours is older, please try to upgrade to SR6.
If your Origin8 is SR6, please let me know the step-by-step procedure how you get such wrong result.
Hope this is the case.

I used a collegue's OriginPro 8.5 program and it worked. Guess it was a bug of the 8 version!
Thank you very much for the help! I am grateful! |
