Dear Zheng,

Thank you for your fast reply,

zoom is one of the option but it is not what I am looking for,

Basically, Graphical window of SAC pop up in a default size, I want to
enlarge this graphical window, I mean, I want larger pop up graphical
window. One of the way doing this, change my computer screen for example
using 23 inc screen, but I suppose pop up large graphical window will
do the same effect without change my screen.

All my best

Sac can zoom in.
You need use keyboard.
After 'ppk'
Move your cursor to say t=5 sec
And press 'x' from keyboard.
Then move the cursor to say t=10 and then press 'x'. Sac will magnify the portion of waveform between 5 and 10 secs. When u r down , press 'o'.

Dear SAC users,

I am using SAC for my seismogram analysis. I prepared a SAC macro which help me see the wave forms and pick the arrival times.

My question is when I read my data with read command in sac and plot them with ppk, a Graphic window is opened and I can see the wave forms but my computer screen is not so big so that I have difficulty to see exact time of arrival time. I am using my mouse to get larger of Graphical window. but the ne wave forms open small size. What I want to do is, I would like to get larger graphical window using sac commands in a macro.

I tried 'window' command but it did not worked. it does not much effect to size of seismogram.

Do you know how can increase size of opening graphical window after typing 'ppk'

Best wishes
