Error Bar in React Chart component
4 Apr 202324 minutes to read
Error Bar
Error bars are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement. To render the error bar for the series, set visible as true and inject ErrorBar module into the services.
