Hello.

I can't find a very "basic" tutorial about data file plotting and I have very simple questions.

Assume that we have a file that contains :

0.5 0.2

0.3 0.9

0.4 0.1

0.7 0.6

The first thing to do is to read data. I have no problems for that :

mydata:=readdata("test.txt",2)

Then

mydata=[[0.5,0.2],[0.3,0.9],[0.4,0.1],[0.7,0.6]]

Question n°1

Hello.

My question is quite simple : how can we define the size in pixels of a plot ?

After plotting we can change the size of the image with the mouse but it is quite approximative.

For example is it possible to display (by default) all the plots of a worksheet in 800x800 pixels ?

Thank you very much.
