I have plotted Histogram, now I need to remove the middle part of the plotting data on histogram, in details I need to plot only first part i.e 1% to 10% and last part i.e 60% to 100% so, I need to remove middle part i.e 10% area to 60% area on histogram plot, how to do that.

Define "remove". Do you want to simply zero out the middle bins (and they'll plot as a flat line along the axis), or do you want to somehow clip out the middle chunk of the bar chart (in which case you'll have to reassign the tick marks on the x axis)?

Hi.

I=imread('cameraman.tif');
h=imhist(I);
h(ceil(1/10*256):floor(6/10*256))=0;
bar(h,.2)
