Power BI Charts 2: Histogram

This is a also a very common basic chart. Histogram plots the frequency of occurrences. The input required for this is just one column of data.

Here is an example of a Histogram of quantity of items ordered from the Northwind databases' [Order Details] column.

Note that R does not interpret Quantity as a numeric and further processing of data is necessary before it can be plotted using R Script in Power BI.

Note: Without the unlist() dataset1 will be double. With unlist() it becomes a numeric.

===============
dataset1=as.numeric(unlist(dataset))
hist(dataset1, main="Distribution of Quantity")
