rakun	Posted - 05/27/2024 : 03:07:08 AM I'm so new to the Origin and I need to plot a huge data set but not all columns are necessary so I need to write a script. I need to select (x,y) pairs with respect to the following parametrization parm = floor((end - start) / (i * 2)) + 1; so my script is double start = 1; double end = 200; double i = 20; int parm = floor((end - start) / (i * 2)) + 1; int X[parm]; int Y[parm]; for (int k = 0; k < parm; k++) { X[k] = start + k * i * 2; Y[k] = X[k] + 1; } for (int k = 0; k < parm; k++) { if (X[k] <= end) { wks.colSel(X[k], 1); } if (Y[k] <= end) { wks.colSel(Y[k], 1); } } I keep receiving "#Command Error!". I just can't understand where is the problem. Does anyone have any suggestion?

aplotnikov	Posted - 05/27/2024 : 06:06:52 AM LT does not support array declaration in C-style with square brackets, you have to use loose datasets instead: dataset dsX, dsY; int k; loop(k, 1, parm) { dsX[k] = start + (k-1) * i * 2; dsY[k] = dsX[k] + 1; } https://www.originlab.com/doc/de/LabTalk/ref/Datasets PS. You can save time by reading of manuals.
