### 例子

```python
from aspose.cells import Workbook
from aspose.cells.charts import ChartType, ErrorBarDisplayType, ErrorBarType

workbook = Workbook()
cells = workbook.worksheets[0].cells
cells.get("a1").put_value(2)
cells.get("a2").put_value(5)
cells.get("a3").put_value(3)
cells.get("a4").put_value(6)
cells.get("b1").put_value(4)
cells.get("b2").put_value(3)
cells.get("b3").put_value(6)
cells.get("b4").put_value(7)
cells.get("C1").put_value("Q1")
cells.get("C2").put_value("Q2")
cells.get("C3").put_value("Y1")
cells.get("C4").put_value("Y2")
chartIndex = workbook.worksheets[0].charts.add(ChartType.COLUMN, 11, 0, 27, 10)
chart = workbook.worksheets[0].charts[chartIndex]
chart.n_series.add("A1:B4", True)
chart.n_series.category_data = "C1:C4"
for i in range(len(chart.n_series)):
    aseries = chart.n_series[i]
    aseries.y_error_bar.display_type = ErrorBarDisplayType.MINUS
    aseries.y_error_bar.type = ErrorBarType.FIXED_VALUE
    aseries.y_error_bar.amount = 5.0
