_D_e_s_c_r_i_p_t_i_o_n:

     Plot a histgram of the expression levels of one or more microarray
     data distribution at a time  containing all gene in the microarray
     slides.

_U_s_a_g_e:

     EachMicroarrayDataDistView(begin, end, expr.matrix, n.changed)

_A_r_g_u_m_e_n_t_s:

   begin: the beginning microarray number to plot 

     end: the ending microarray number to plot 

expr.matrix: a microarray expression matrix object with rows containing
          a gene expression  levels across multi-experiment while
          columns denoting expression levels of all genes contained in 
          one microarray slide. 

n.changed: the number of genes that differentially express 

_D_e_t_a_i_l_s:

     View a microarray expression level distribution containing all the
     genes in the slide. Normally, we could perform further statistical
     test and find it is a normal distribution with
     'u=mean(vec),S=var(vec)', vec is the expression vector of a
     specified microarray.

_V_a_l_u_e:

     No value returned.
