What is 2D bar chart excel?
A bar chart is an arrangement of bars of different lengths to
represent values, laid out horizontally. They are typically used to
graphically illustrate the different values in a spreadsheet, and
how they compare to other related values. Different bars are
different colours and can be labelled to show what they correspond
to. You can also have groups of bars of similar kinds, so the the
same colour may be repeated in sets. You can also have stacked bar
charts, where different parts of one bar are made up of different
colours, to show how much the contribute to a total. See the links
below for examples.
