GT-Force	Posted - 02/11/2010 : 11:28:46 AM I am trying to do this: I have an XY scatter graph of a column, and I'd like to manually mark two regions by using the regional data selector. Then, I need a script that will fit a line to the first range, displaying at least the slope, and will give me the max, min and max-min for the second range. I have not used Origin before. I guess doing this should be trivial for someone who knows Origin, but I spent a few hours trying to do this to no avail. I'm only visiting a lab and do not have much more time left. If you can send me the script to do this, with instructions about how to assign a keyboard shortcut or create a toolbar button for it, I'd really appreciate it. Thank you.

easwar	Posted - 02/16/2010 : 09:10:20 AM Hi GT, Once the statement "stats r2" is executed, the min, max values are accessible via double dmin = stats.min; double dmax = stats.max; double diff = dmax - dmin; //etc Then you can build a string for the text such as: string mytext$ ="Min = $(dmin), Max = $(dmax), Diff = $(diff)"; You can then place text in a lablel in the graph, see this topic: http://wiki.originlab.com/~originla/wiki/index.php?title=Script:Creating_and_Accessing_Graphical_Objects As to running the script from a button, easiest is to assign the script to the custom button, see this topic: http://wiki.originlab.com/~originla/wiki/index.php?title=Script:Getting_Started_with_LabTalk You can also create your own custom toolbar or buttons, see this topic: http://originlab.com/www/helponline/Origin/en/mergedProjects/QuickHelp/QuickHelp/How_do_I_create_custom_toolbar_buttons_that_run_my_script_macros.html Also, at the end of your script you may want to add the linke mark -r; This will remove the data markers from the graph.

GT-Force	Posted - 02/15/2010 : 11:14:18 PM Thanks for the script. Yes, the y data of the 2nd selection. But I am not interested in all of the stats, but just the min, max and (max-min) values. Is there a way to do that? And is there a way to run this script by assigning it to a toolbar button or keyboard shortcut? Thanks again. GT
easwar	Posted - 02/15/2010 : 10:56:48 PM Hi GT, There is an x-function named get_plot_sel which can be used to get ranges corresponding to the two selections. You may need to update your Origin to 8.0SR6 (free patch) for that to work. Here is a script segment that does LR on the 1st selection. Was not very clear what you wanted stats on, I am assuming you wanted stats on the y data of the 2nd selection. Easwar OriginLab // Assume graph is active with two ranges selected // Get selection to string string sel$; get_plot_sel str:=sel$; // Declare range using 1st selected range range r1 = sel.gettoken(1,"\|")$; // Perform linear fit fitlr r1; type Linear fit results from 1st part:; fitlr.=; // Declare range of the y data for 2nd selected range range -w r2 = sel.gettoken(2,"\|")$; // Compute stats stats r2; type %(CRLF)Stats results from 2nd part:; stats.=;
