Barcharts
Joseph Priestley 1765
“…a longer or a shorter space of
time may be most commodiously
and advantageously represented
by a longer or a shorter line.”
William Playfair (1759-1823)
‘Commercial and Political Atlas’
of 1786. Playfair is credited with
developing a range of statistical
charts including the line, bar
(histogram), and pie charts.

The Gantt Chart(s)
• Barcharts pre-date Gantt by 100+ years
• Gantt’s charts focused on production
• Are the forerunner to Earned Value
• But quickly declined in use
“managers would rather show what they
had done rather than consider what
could have been achieved”
