# Creating a histogram with specified data

I tried making a histogram with following criterion.
x = 2.5*randn(1,100000)-1.7
hist(x,[-6:0.25:4])
The middle part of the histogram looks fine to me. But there's two werid solid blocks at the beginning and end. Does anyone know how to fix it? Here's the photo for your reference. Thank you.

If you want two remove those extra blank space, you can use xlim (Limitinng x axis scale).
x = 2.5*rand(1,200)-1.7
hist(x,[-6:0.25:4])
xlim([-2 1])
Please note technically you have to keep all scale ranges, as hostogram shows the repetions in different ranges (all possible scale ranges, any particular value is not thres, then it shows 0 level).
If you looking for different issue, then let me know detail?

x = 2.5*randn(1,100000)-1.7
data1=-6:0.25:4;
hist(x,data1)
xlim([-5.8,3.8]);
Here I have just limiting the scale range. Please note you use to hist of 1 D array to plot the hist (x and data1=[-6:0.25:4];)
or
remove those data in the vector itselt
x = 2.5*randn(1,100000)-1.7
data1=-6:0.25:4;
hist(x(-5.8<x & x<3.8),data1(-5.8<data1<3.8))
