What is errorbar?
Error bars are graphical representations of the variability of data. They are used to indicate the error or uncertainty in a reported measurement. Error bars give a general idea of how precise a measurement is. For example, say we want to give a prediction about car sales for the next 12 months, but we are not 100% sure about our prediction. In order to indicate this uncertainty, we would provide a relative possible error. Error bars often represent one standard deviation of ...
