Histogram

A histogram shows how often values fall within specific ranges, helping you quickly identify the distribution, such as whether values are concentrated, spread out, or skewed.

Chart setup to build a histogram:

Axis

Drag the dimension to plot on the axis (e.g., Age).

Values parameter

Drag the measure you’d like to analyze to view its distribution in the histogram (e.g., Bill Amount).

Chart type

Select Histogram Chart from the Chart Type dropdown menu.

Histograms provide a graphical representation of data distribution, making it easier to identify patterns. In this example, the histogram shows the bill amount for specific age groups.

1.1. Show cumulative bar

In a traditional histogram, bin values are totaled separately. In a cumulative histogram, each bin is the sum of the values in a bin and all previous bins.

1.2. Bin

Options: You can plot the histogram by specifying the interval or defining the total number of bins. You need to specify the number of bins or the size of each bin accordingly.

Type: Histograms plotted based on the number of bins can have closed intervals or semi-closed intervals.

1.3. Underflow bin

An underflow bin is used to group all data points that fall below the minimum value of the range of the defined bins. This is particularly useful when dealing with datasets where some values lie outside the specified range and need to be accounted for separately.
