A plot that counts the observations in adjacent bins and draws a bar for each. Its look depends on the bin width and starting point, which is why a kernel density estimate is often drawn alongside it.
In Descriptive statistics
A histogram counts the data in a set of bins and draws a bar for each; its look depends on the choice of bins. A kernel density estimate smooths the data instead, placing a small bump at each observation and adding them up; its look depends on the width of the bumps, the bandwidth. Both show the same thing here: most patients near 1 mg/dL and a thin tail stretching to 9.
