schneide	Posted - 03/06/2018 : 03:17:15 AM Origin Ver.2018 and Service Release (Select Help-->About Origin): b9.5.0.193 Operating System: win7 I have a graph window with multiple plots (xy-datasets) in one layer. I would like to programmatically retrieve statistical values such as min, max over all plots combined. I can do this manually by the menu-GUI "statistics on columns" by selecting - input data: "combined as single data set" and - DataRange: by clicking on the plot I do not manage to do this programmatically, esp.: -How do I retrieve a range that contains all plots in the graph? -How do I perform statistics over all plots from this range combined? By the way is there a way to find out the code which is executed when I perform a calculation manually by configuring a menu-GUI item? Giselher

schneide	Posted - 03/07/2018 : 06:00:02 AM Yes, this did the job, All I had to do now was to add label -rc rect; at the end to remove unwanted output onto the graph window. And to process the information in the tree variable. Thanks, Giselher
yuki_wu	Posted - 03/06/2018 : 10:26:21 PM Hi Giselher, I think you could try the X-Function: addtool_curve_stats //Execute XF to create gadget addtool_curve_stats; //Declare LT gadget variable gadget gg = rect; //Expand ROI to full range gg.expand(); //Define a tree variable tree mytr; //Output result to the tree variable mytr gg.getresult(mytr); //view the tree variable mytr.=; For more info, please refer to these pages: https://www.originlab.com/doc/X-Function/ref/addtool_curve_stats https://www.originlab.com/doc/LabTalk/ref/Gadget-obj For some X-Functions, there is Generate Script context menu to generate X-Function Script. Let us take the addtool_curve_stats X-Function as an example: 1. Select Gadgets: Statistics: Open dialog from menu 2. Set the options in the dialog as usual 3. Click the triangle button at the upper right corner 4. Select Generate Script from the context menu, then the Script Window will pop up with the script Hope it helps. Regards, Yuki OriginLab
