Hi,
You may do the following:
1, plot a graph with your XY data (in which X is the (1/T)^(1/4) and Y is the resistivity), suppose this is graph 1;
2, double click on the x axis in graph1 to bring up the axis dialog, go to "Title&Format" tab;
3, select the "top" axis and check the "show axis and ticks" box, click "apply" and the top X axis should be shown in the graph(but without tick labels yet);
4, go to the "Tick Labels" tab, for the top axis, check the box before "Show Major Labels", to show the major labels as numeric.
5, close the axis dialog, and go to the command window; (Normally it should be open when you launched your origin, but if it is not, you may open it by choosing "Window:Command Window" or use the short key "Alt+3")
6, in the command window, use the following script:
layer.x2.label.formula$ = "1/(x^4)"
This will place labels on the top X axis, at the same positions corresponding to labels in the bottom X axis, and these new labels will represent values that are computed using the specified formula. And the formula "1/(x^4)" is the one you used to calculate T value from (1/T)^(1/4).
At last, you should have a plot similar to the following figure,
Hope this information helps!
