However, the nature of most progress bars is somewhat 'stuttery' and I gather the reason why is something like my diagram below: For some reason progress bars seem to be divided into equal sections for the number of tasks to be completed, so in my example, 33% will be given to a ...
In addition, note that all I-V datasets accept only up to 100 data points. Exceeding this number of data points will prompt an error on the ibischk parser test. Set the increment of the.DCcommand such that the resulting number of data points is less than or equ...
