How to replace xtick labels on histogram plots properly?

Hello, So i am plotting a histogram of log values and i want the xaxis to show the corresponding linear values. edge_tl are the actually bin edges for the histogram (of log values - negatives) edge_test are the inverse of those values both are of a size 1 x 39

   histo_totl=histogram(hist_values(:,5), edge_tl); 
    edge_test=10.^(edge_tl);    %changed the bin (log values) to linear values to put them on xaxis
    set(ax1,'XtickLabel',edge_test)

The problem is that the xaxis replaces the major ticks (which are four) with the first four values of the edge_test array instead of taking it as a whole to replace the edge_tl.

A second thing is i would like to show the edge_test values as powers of 10. Using Xscale, log at the moment isn`t working. Thank you
