Box whisker charts depicts data through their quartiles. The top of the box represents the upper quartile and the bottom of the box represents the lower quartile. The median of the data is presented as a line through the box. The whiskers are the lines extending vertically from the box that indicate variability outside the upper and lower quartiles. Outliers may be plotted as individual points.
Box whisker plots are ideal for comparing distributions of data since the median, spread and overall range are immediately apparent. Within EnviroInsite, data can be charted by location or by constituent.
