Thank you for your reply Gabor,
sure, the manually written axis works fine in any configuration.
but I would prefer an "automatic" input.
That means that I would like to use the datafield[1] for the minimum
time and the datafield[max] (means the last one) for the maximum time.
divided into x steps.The datafiled size could reach more than 7000 sec.

With regards Carmen
