# X/Y Error Bars

Use the X or Y Error Bars dialog to display error bars for 2D charts.

Choose Insert - X Error Bars, or Insert - Y Error Bars (Charts)

An error bar is an indicator line that spans over a range from x/y - NegativeErrorValue to x/y + PositiveErrorValue. In this term, x or y is the value of the data point. When "standard deviation" is selected, x or y is the mean value of the data series. NegativeErrorValue and PositiveErrorValue are the amounts calculated by the error bar function or given explicitly.

The Insert - X/Y Error Bars menu command is only available for 2D charts.

## >錯誤分類

在 [錯誤種類] 區域中，可選擇顯示錯誤種類的不同方式。

### 無

Does not show any error bars.

### 常量

Displays constant values that you specify in the Parameters area.

### 百分比

Displays a percentage. The display refers to the corresponding data point. Set the percentage in the Parameters area.

### 函式

選取函式以計算誤差線。

標準誤差：顯示標準誤差。

Variance: Displays the variance calculated from the number of data points and respective values.

Standard Deviation: Displays the standard deviation (square root of the variance). Unlike other functions, error bars are centered on the mean.

Error Margin: Displays the highest error margin in percent according to the highest value of the data group. Set the percentage in the Parameters area.

### 儲存格範圍

按一下 [儲存格範圍]，然後指定要從中擷取正誤差線值與負誤差線值的儲存格範圍。

### 來自資料表格

For a chart with its own data, the error bar values can be entered in the chart data table. The Data Table dialog shows additional columns titled Positive X or Y-Error-Bars and Negative X or Y-Error-Bars.

### 兩者的值相同

Enable to use the positive error values also as negative error values. You can only change the value of the "Positive (+)" box. That value gets copied to the "Negative (-)" box automatically.

## Error Indicator

Specifies the error indicator.

### 正數與負數

顯示正誤差線與負誤差線。

### 正數

僅顯示正誤差線。

### 負數

僅顯示負誤差線。
