Returns an ErrorBar object representing the vertical error bars for the series.
Error bars graphically express potential error amounts relative to each data marker in a data series. You can add error bars to data series in two-dimensional area, bar, column, line, scatter, and bubble charts. In scatter and bubble charts, you can display error bars for x values, y values, or both.
The series type does not support error bars in the Y direction. Pie, Doughnut, Surface, Radar, and 3D charts do not support vertical error bars.
