My main problem right now is to find a way to: - Control the specific time of the trend in order to set the limits of the curve, for example, if I view two or more curves (I only have one trend tag, but with some different values in datalog) and just need to print just one in a specific range I can't do it with he forward and backward buttons of the trend because It is not possible to set the start and end of the curve in the graphics. I can see a ruler in the F(X) trend but I don't know how to set a date/time values (like the normal trend view) in the X axis. - To be clear, I'm only acquiring data from a pressure transducer, these values are being also log in another screen in a trend view using datalog, operators perform several test and they need to print the specific values in the specific times of the curve, It is not possible to save in CSV or SQL , TXT I'm doing in it in RDB to avoid any value modification and make sure that the values are not being cheat. when they review the datalog file in the trend, they want to specific select the values from a start time and stop time. Another thing is how to print this graphic in a JPG or another graphic format? because when I use PDF creator and do a snapshot of the graphic, resolution decrease. It is possible to increase the line width? I've being looking in the FAQ's and thread of the forum even in the online help, Wincc advancedSP2 manual but I cannot see it, just the table values, text among others, nothing related to increase line width. So if anybody could give me some hints about this issues, I'll be greatfull. specially in how to set a date/time values in the F(x) trendview, because this one could be helpful if I cannot do it with the normal Trend view..the F(x) trend will show the logged values of the curve regarding to time and I don't know how to configure it . Thanks and Best Regards.

What options are there for creating a screenshot in WinCC flexible ES, WinCC flexible Runtime or on panels? You can save values of tag about script in a text file. How on a PC with WinCC flexible can you use a script to save and read out information in a text file? Tweety
