I am new with Matlab and need some help:
I have financial data that I can produce from another application to a text file.
the text file structure will be like: (I can change it)
The left column (1,2,3,4,..) represents the time in minutes.
The right collumn represents the values that I want to see in the Y axis.
I iuse the File->Import Data to import the data text file into Matlab.
1) How to write the command for plotting the graph?
2) In case that I want to have a graph of 10 min intervals instead of 1 minute intervals, how to do it from Matlab?
3) When there is no data (e.g. weekend) the right column gets value 0, What is the recommended solution for showing 0 data on the graph(but only as indicator, not spending too much graph space)?
4) How to scale the Y axis to show the correct values? (In this example from 0.9 to 2)
