我有一个 Excel 表，前两列中有一些数据。我用这些数据创建了一个简单的图表。我在向图表添加轴标签时遇到问题。

这是我的脚本

from win32com.client import Dispatch, constants
excel = win32com.client.Dispatch('Excel.Application')
wb = excel.Workbooks.Open( 'output_data.xls', False, True)
excel.Visible = False
ws1 = wb.Worksheets('sheet_1)
ch = ws1.Shapes.AddChart( 73, 200, 50, 800, 500).Select()
excel.ActiveChart.ApplyLayout(1)
excel.ActiveChart.SetSourceData(Source=ws1.Range("$A:$B"))
excel.ActiveChart.ChartTitle.Text = "Integral"
excel.ActiveChart.Legend.Delete()

--------到这一切都很好。

excel.ActiveChart.axes(constants.xlCategory).AxisTitle.Caption = "Z_coordinate"

但是当我添加轴标签时，它返回一个属性错误 xlCategory。

如何添加轴标签并更改字体大小。

提前致谢。

You probably used the wrong enum axis type. Each enum (as far as I can tell) only works for certain types of charts. According to the built-in macro recorder (very useful even for python-based scripts, btw), scatter plots use xlValue, not xlCategory. Try one of the other enums until your code works.

I haven't fully figured out Excel in win32com yet, but I managed to get axis titles to appear after a bit of trial and error. Here's a short snippet from some code I wrote for an XY scatter plot with titles for X axis, Y axis, and Y2 axis:

    Foo = chart.SeriesCollection(1)
    Bar = chart.SeriesCollection(2)

    Bar.AxisGroup = 2

    Primary_Axis = chart.Axes(AxisGroup=xlPrimary)

    Foo_xAxis = Primary_Axis(1)
    Foo_yAxis = Primary_Axis(2)
    Foo_xAxis .HasTitle = True
    Foo_yAxis .HasTitle = True

    Bar_yAxis = chart.Axes(xlValue, AxisGroup=xlSecondary)
    Bar_yAxis.HasTitle = True

    Foo_xAxis .AxisTitle.Text = "Primary X axis string"
    Foo_yAxis .AxisTitle.Text = "Primary Y axis string"
    Bar_yAxis.AxisTitle.Text = "Secondary Y axis string(Y2)"
