k_fadz	Posted - 10/30/2017 : 04:14:19 AM Hello, I am trying to do a labtalk script that opens a window in which I choose the columns to be plotted ... the script would then read the column's I entered and plot them over column 1 (time). In all there's 101 columns (starting from col(2)) named "M/z = 1", "M/z = 2", "M/z = 3" ... "M/z = 101"). I don't have an idea .. Any help would be greatly appreciated K.F

Hideo Fujii	Posted - 10/31/2017 : 10:11:12 AM Hi K.F., The syntax of plotxy iy:=[Book1]!(1,$(nn$(ii)+3)) plot:=200; seems okay, but your code doesn't have nn13. Hope this suggestion helps. --Hideo Fujii OriginLab
k_fadz	Posted - 10/31/2017 : 04:17:47 AM Sorry I forgot the screenshot. As you see my M/z starts at the 4th column (it continues till column 104 where M/z=101). When I enter 17, 18 and 44 for nn1, nn2 and nn3, the error pops up ... (I have 104 columns in my worksheet though). I tried the check box, but I think entering the numbers directly is better since I have 101 possible checkboxes. Thank you so much, you're really helping me
yuki_wu	Posted - 10/30/2017 : 10:52:21 PM Hi K.F, I am sorry that I cannot find the screenshot. You may forget to upload it. I guess the error is caused by: plotxy iy:=[Book1]!(1,$(nn$(ii)+3)) plot:=200; For example, if I set nn3 = 20, the script above will create a plot with column(1) and column(23). If column(23) doesn’t exist in the active worksheet, an error message will pop up. BTW, I think checkbox is a better option. For example: getn (column1) nn1:2 (column2) nn2:2 (Which column would you like to plot ?); Hope it helops. Regards, Yuki OriginLab
k_fadz	Posted - 10/30/2017 : 11:53:38 AM Thank you so much Yuki ! Your answer was really helpful I am now using this code to draw each column in a distinct layer (I am working on the formatting and will probably make a new topic...). win -a book1; //Pop up a dialog and enter the columns index getn (M/z) nn1 (M/z) nn2 (M/z) nn3 (M/z) nn4 (M/z) nn5 (M/z) nn6 (M/z) nn7 (M/z) nn8 (M/z) nn9 (M/z) nn10 (M/z) nn11 (M/z) nn12 (M/z) nn14 (M/z) nn15 (M/z) nn16 (M/z) nn17 (M/z) nn18 (Which M/z would you like to plot ?); //loop to plot each column in distinct layer for(ii=1;ii<=18;ii++) { if (nn$(ii) == 0) {continue;}; //zeros are ignored this way plotxy iy:=[Book1]!(1,$(nn$(ii)+3)) plot:=200; nn$(ii)=; } I have a problem with the loop (part in red). In the dialog window I have 18 values. When I iterate till 18 to get all the M/z i want to plot there's an error that show up (see screen shot attached). This error disappears if I replace 18 by 13 or less in the loop (for(ii=1;ii<=13;ii++)...). Any suggestions ? K.F
yuki_wu	Posted - 10/30/2017 : 06:49:21 AM Hi K.F, You can use GetN funtion to pop up a dialog. For example: //Pop up a dialog and enter the column index in it getn (Column Index) nn (Enter the column index to be plotted); //Check the value of nn nn=; More information please refer to: http://www.originlab.com/doc/LabTalk/guide/Getting-Numeric-and-String-Input#Get_Multiple_Values http://www.originlab.com/doc/LabTalk/ref/GetNumber-cmd Hope it helps.
