Dear friends,
I want to change the maximum and minimum value of X-Axis that displayed.
For example, the input of Ydata is an array by size 500 but i want to
x-axis minimum & maximum values be 50 & 100 and the axis changes
between these values.
In real our data are very huge, so we must use paging. so, i must can change the labels of X-Axis ( minimum & maximum labels) . what must i do?
PLEASE HELP ME!
thanks, Majid.
