x=[1,-2,4,6,-5,8,10];
stem(x);

i want to plot x , but x(0)=-5.

If you don't want just default x-axis values of 1 upto the length of the array you need to define the values and plot e.g.

stem( x, y )

where y would normally be what you have called x and x would be e.g.

x = -4:2
y = [1,-2,4,6,-5,8,10];

I guess if you want x = 0 at y = -5.
