Hi,

it“s my first time I`m working with origin and I downloaded the testversion. I`m writing my seminarpaper and would like to create a temperature topography of a sample surface. Therefore I have got the following database:

I have got three temperature measurements along the length of the sample T(x) at different points of the crosssection. For Example: One in the middle of the sample, the next one shifted by 5mm from the middle and the last one shifted by 10 mm from the middle.

Now, I would like origin to create a topgraphicle Temperatureprofile by interpolation between these 3 curves.

I already tried to create it by the funktion 3D surface plot, but origin doesn“t interpolate between the three curves. between the fix x terms, it shows a temperature of 0°C.

I hope you understood my proble. I would be very pleased, if somebody could help me.

sincerly,

dickie

Hi,

I found a solution. The problem was, that the time steps weren`t equivalent. Now, I averaged the time steps. The result is, that I can youse the fixed column for the time and distance respectively. Afterwards I only have got to scale this axis to my steps é voilį it works.

Hello dickie,

It may not be enough to generate a topograph if only three curves are provided, unless the temperature distribution varies quite slowly?
