Dear Philipp,
thanks for you help. I tried to adopt your Code to my programm. No
success. There is a prolbem I should have metioned eralier. The time
between each datapoint has a different time period. So I cant print the
y-axis over the time and add a a secound x axis for the line of
document. I might stick to the plotxyyy.
Best regards
Frieder
