An error bar is an indicator line that spans over a range from y - NegativeErrorValue to y + PositiveErrorValue. In this term, y is the value of the data point. When &quot; standard deviation &quot; is selected, y is the mean value of the data series. NegativeErrorValue and PositiveErrorValue are the amounts calculated by the error bar function or given explicitly.
误差线是跨越 y - NegativeErrorValue 到 y + PositiveErrorValue 区域的一条指示线。y 是数据点的值。当选择“标准偏差”时，y 是数据序列的平均值。NegativeErrorValue 和 PositiveErrorValue 是由误差线函数或明确的给定值所计算的量。
