Xticklabels with exponential to the end of the axis

Question

I've this problem with tikz package. I'm creating a plot in the x-range [0; 10000] (in my real plot, up to 100000) but the xticklabels are in the form [0, 0.2, 0.4, 0.6, 0.8, 1] and at the end of the axis there is 10^4. I'd like to get the xticklabels in the form [0, 2000, 4000, 6000, 8000, 10000]. Can anyone help me? Thanks in advance.
