While going through Wikipedia's article History of statistics
In 1786 William Playfair (1759-1823) introduced the idea of graphical representation into statistics. He invented the line chart, bar chart, and histogram and incorporated them into his works on economics, the Commercial and Political Atlas.
William Playfair(22 September 1759 – 11 February 1823) invented the line chart, bar chart, and histogram.
And in the Histogram article
A histogram is an approximate representation of the distribution of numerical data. It was first introduced by Karl Pearson.
academic and learned online publications, take this extract from an online entry for “Karl Pearson: “Two days later he [i.e., Pearson] introduced the histogram – a term he coined to designate a 'time-diagram' to be used for historical purposes”
Histogram was first introduced and coined by Karl Pearson(27 March 1857 – 27 April 1936).
The context is not clear and I'm a bit confused on the invention of Histogram.
Does anyone know who first invented/introduced a Histogram? I would be happy to receive any additional reference from you.
