A recommendation to handle graph-dataset changes would be great. #1/ unique function: I tried the code from: https://www.originlab.com/doc/LabTalk/ref/Unique-func In the text-column A the cells have: 1,10,3,A,B,1,A inside for testing. Code from webpage: StringArray sa; sa = unique(col(a)); // assign unique values in col(a) to stringArray sa, sort in ascending order range bb=col(b); sa.CopyTo(bb); // copy contents of stringArray sa to col(b) The code does not work – i.e. it seems the transfer from the unique function to the stringarray has problems because if one directly writes “col(b)=unique(col(a));” it works. There is no error message and on the webpage I see no limitation of this function to a special origin-version. #2/ Some questions to dataset/stringarray: The dataset with –a option should be able to accept numbers and text: dataset -a test={1,2,A,B,A}; (A or “A” makes no difference) but test[1]$= shows correctly the 1 but test[3]$= shows only –- I can’t transfer text to the dataset –a. What point do I miss working with the dataset –a with text? #3/ how can I transfer text/numbers between datasets and stringarrays? Since I am stuck using dataset –a with text I could not test it yet but would this work? Stringarray arr; Dataset –a dat = col(a); Arr.append(dat); // move text/numbers from dataset to array Dataset –a sec; sec=arr; // move text/numbers from array to dataset #4/ How to switch on/off data in plots Using the search function I could not find a similar topic. I have several datasets from experiment-variations inside my project. The different data from e.g. expA and expB … are stored in different worksheets. Currently I add them to predefined graphs (>15 plots) when I load the data to the project. Later I only want to see the plots from data e.g. expA and expD but not all other data inside the project. What would be a good solution to switch on/off the data inside the plots without having to activate every graph by hand? Later on I want to compare other data so the changes must be reversible. Currently my approach is to work with a “archive” worksheet where I store the name of the worksheetname=experiment-name in the first column and in a second column I can write an “x” or not depending on whether I want to see the data inside the plot. A script then checks whether there is an x or not and switches on/off the data inside the graphs (the row-number of the data inside the archive is the same as their row-position in the plot-data-definition). Is there an easier way? Origin has so many options/functions sometimes it is difficult to find already available solutions. Thanks for your help. Best regards, Karsten8.
