Vertical interpolation not operating as expected

V3 BETA TESTS
1

If I select the 10-1 rev cells in the 60C column (values 0,31, 55, 57) and right click for “vertical interpolation”, the result does not appear to process the 0 value endpoint correctly (at 60C, 3 revs).

before interpolating the cell values are 0, 31, 55, 57:

after interpolating the cell values are 0, 44, 51, 57:

I would expect values like 0, 19, 38, 57. Is this due to the non-linear Y axis? Is it actually interpolating linearly on a per rev basis?

I performed a similar action on the VE 1 table and it behaves as expected.

Look on Y axis is 1 2 3 and 10 revolution
Maybe interpolation is tonthe value not cells number

It interpolates according axis value. So it is correct as you interpolate linear you need to get a straight line between the points.

Ok, I get that. The table has non-linear axes so the interpolated values in the table are similarly non-linear, even thought the interpolation is linear. The graph makes that apparent. Thanks for the response.

I check the documentation before posting, maybe add a note to the section on interpolation? Something like:

Note: Interpolated values in tables with non-linear axes will appear non-linear. See the corresponding graph to observe the linearly interpolated values.

Thank you for the suggestion. I add this note to the documentation.

You’re welcome, glad to help. Documentation is always a monumental task and is especially difficult when product development is in high gear. I’m always glad to see the documentation improvements that come with each beta release.
