how to read a cell's value from a line

Just in case you can't find them, there are a couple of links to tutorials at the bottom of this message. Once you work through them, Google more.

this is what i do .

the matter is .in my waveform . i just have zero 

[Dennis_Knutson]

That's because you are not using the 2D array output.

[Dennis_Knutson]

It is also just silly to keep reading the same file over and over. Move it to outside the loop. Same thing for the Index Array if it's always the same column.

[pousse]

if i do that ,anything is working. i am going to explain you what i want to have.

[Dennis_Knutson]

That makes no sense. How do you create a waveform from a single point?

[pousse]

you read the value of the point.

if the first line is over. we start the second one. 

values which are in a same column will be in a same waveform. 

for example 10 and 40 are in a same waveform

[Dennis_Knutson]

I have a hard time understanding. With a single index array, you can read all columns and write to separate graphs.

I think this will do what you want.

This assumes your text file is tab delimited. I tried it out by creating a text file from the image you originally posted.

cool .

and how to put it in three different waveform . each of them has his own waveform
