<p>Hi Jeong Hee,<\/p><p>I think you can not specify the operation in visualize using script. Either you have to create a new dataset with the squared values, and then visualize that dataset. Or you can simply plot the square values using the plot<\/a> script command and then use write<\/a> to save the values into a text file. I wrote a sample script to plot data and write them into text file, that might be useful for your case:<\/p><\/p>\n
