Hi Guys,
I recently picked up the "Smoothing Contour Lines" Topic, I had posted here a couple of weeks ago.
Kathy suggested, that I should convert my XYZ Data to Matrix Data, in order to be able to smooth my plots and extrapolate the Data.
However, the w2m X-Function should only be used if the X/Y Values in the source worksheet are uniformly spaced, which is unfortunately not the case. So I tried to use the plotvm X-function, but I wasn't even able to create any graph with my data.
In the first picture below, you can see how my dataset looks like.
In the second picture you can see the contour plot, I created with this data using the following code:
//define axes;
wks.col1.type=4;// Make Col1 type X.
wks.col2.type=1;// Make Col2 type Y.
wks.col3.type=6;// Make Col3 type Z.
//draw contour Plot
work -s 1 1 3 100; //mark columns
menu -e 35581; //draw contour plot
What I'm trying to is:
1) Smooth the contour lines, they look too edgy
2) Extrapolate the data. Although the maximum Value for eta(contour lines) is about 0.7, I would like to show Contour lines that go up to about 0.8.
3) I need to implement this graph/data manipulation with a LabTalk script.
Additional Question:
I found out, that its possible to extract the contour lines out of the contour plot. Is it possible to use this extracted data to somehow extrapolate the contour lines.
I hope I explained my problem well enough!
Thank you in Advance,
Sebbey
