Support Resolution Time Histogram

A histogram groups continuous numeric observations into adjacent ranges and counts how many observations fall in each range. This example uses customer-support ticket resolution time, with two-hour bins from zero to twelve hours. The bar heights show where resolution times cluster and whether a smaller group of tickets takes much longer. This is different from a bar chart of issue categories: the order of histogram bins comes from the numeric scale, and the bars touch because the ranges are continuous. Start with raw values or a clear frequency table, choose sensible equal-width bins, and label both the measure and the count. Adjust the bin width if the chart hides useful structure or becomes too noisy.

자주 묻는 질문

What data do I need for a histogram?

You need numeric observations, such as times, scores, sizes, or measurements, or a frequency table for numeric ranges.

What is a bin?

A bin is one numeric interval used to group observations, such as 2–4 hours.

Can I choose the bin width?

Yes. Choose a width that shows the distribution clearly and use equal widths unless there is a reason not to.
