i want to calculate entropy of histogram for that i need to find total number of pixels at given value of x-axis.

That does not appear to be possible (at least in R2015b). I would use histcounts (or histc) and then do a bar plot.

i did this too,but i need to find total no of pixels at particular value of x-axis,so that i can calculate entropy from histogram using programming rather than manually.

If you want the entropy, why not just simply use the entropy function
theEntropy = entropy(grayImage);
