Histogram

Visualise the distribution of a single continuous variable by creating a histogram displaying the tabulated frequency in discrete intervals of the data.

Details

A histogram visualises the distribution of data over a continuous interval or certain time period. Each bar in a histogram represents the tabulated frequency at each interval/bin.

Histograms help give an estimate as to where values are concentrated, what the extremes are and whether there are any gaps or unusual values. They are also useful for giving a rough view of the probability distribution.

Output

The example below shows a histogram of sea ice extent in the 1978-2018 period grouped by location.

xYesColumn Input. Decimal, IntegerThe column you want to create a histogram for. The values in this column will be divided into bins based on the bins or binwidth inputs.
fillNoColumn Input. Text, Integer, Boolean, Date, DateTime Maximum of 15 categories.The categories of this column will be used to split each bar in the histogram into different segments. The segments will be coloured by category and a legend created.
binsNoInteger > 0Number of bins to split the x-axis into. Overridden by binwidth. Defaults to 30 with a warning if not specified.
