Hi,
I am plotting a figure using Polar Contour (Plot--> Contour --> Polor Contour Theta(x) r(y)). The output figure by Origin is like below,
The black dots are the input raw data. It is apparently that Origin has done some type of interpolation for the original raw data. What I what to know is, what interpolation method does Origin use to interpolate raw data in this type of figure ? Thanks a lot.
The x, y and z data set I have used to plot this figure is as follows:
X Y Z
280 1.7 123.94603
173.5 3.1 115.31733
230 1.7 101.78426
332.8 1.4 102.38491
314.4 0.8 119.97431
163.6 3.1 129.61121
206.8 1.7 130.86418
322.4 1.7 148.28239
210.5 3.1 85.28629
263 2.2 131.71093
241.7 3.1 114.24681
254 2.8 156.6991
304.1 2.8 79.55933 |

Here is some description about how we create a 2D contour, we use linear interpolation to find contour lines.
