I wonder if there are following possibilities in Origin:
1. to convert (export) data of graphs and curve fittings to ASCII format (ASCII table) and transfer files to Kaleidagraph
2. to reverse X axis data (I am working with IR spectroscopy data. Scale goes from 4000 to 500 from left to right. Although I import IR spectra as ASCII file which goes 500 to 4000, on the drawing I want to see reverse scale). Simple sorting of data in this case wouldn't work.
1. To export data obtained from curve fittings ... (a) Double click on the fitted to activate the plot details dialog box (b) Click on the worksheet button to create/open the worksheet for the data (c) Export the worksheet data using the Eile .. Export ASCii menu option
2. To reverse the x-axis display ... (a) Click on the layer contain the graph to make that layer active (b) Open the scriopt window (c) Issue the LabTalk command "Layer.x.reverse=1" in the script window
The solution to your second question suggested above certainly reverses the data but it also moves the Y axis and its labels to the opposite side of the graph. You can reverse the data without moving the Y axis by selecting Axis -> X Axis on the Format menu and swapping the From and To values on the Scale tab...
