Question

我遇到了类别轴与值轴相交的设置值的问题。在代码示例下方

import time
import datetime

from pptx import Presentation

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])
chart_data = ChartData()


chart_data.categories = [datetime.datetime.strptime('2012-02-09', '%Y-%m-%d'), datetime.datetime.strptime('2012-04-09', '%Y-%m-%d'), datetime.datetime.strptime('2012-09-09', '%Y-%m-%d')]
chart_data.add_series('West',    (32.2, 28.4, 34.7))
chart_data.add_series('East',    (24.3, 30.6, 20.2))
chart_data.add_series('Midwest', (20.4, 18.3, 26.2))
x, y, cx, cy = Inches(2), Inches(2), Inches(6), Inches(4.5)
chart = slide.shapes.add_chart(
    XL_CHART_TYPE.LINE_MARKERS, x, y, cx, cy, chart_data
).chart
chart.has_legend = True
chart.legend.include_in_layout = False
chart.series[0].smooth = True
points = chart.plots[0].series[0].points
ccount = 1;
period = int(len(points)/1.0)
chart.plots[0].series[0].marker.style = XL_MARKER_STYLE.NONE
for point in points:
    if ccount== period:
        point.marker.style = 8
        fill = point.marker.format.fill
        fill.solid()
        fill.fore_color.rgb = RGBColor(*[0,0,0])
        point.marker.format.line.color.rgb = RGBColor(*[0,0,0])
        ccount = 1
    else:
        ccount +=1

try:
    chart.value_axis.crosses = XL_AXIS_CROSSES.MINIMUM
except Exception as error:
    traceback.print_exc()


chart.has_legend = True
chart.legend.include_in_layout = False
chart.legend.position = XL_LEGEND_POSITION.BOTTOM
chart.legend.font.size = Pt(6)

prs.save('chart-01.pptx')

Python iterpreter显示如下错误：

回溯（最近通话最近）：文件 “”，第56行，在 chart.value_axis.crosses = XL_AXIS_CROSSES.MINIMUM文件“ C：\ Users * \ AppData \ Local \ Continuum \ anaconda3 \ lib \ site-packages \ pptx \ chart \ axis.py”， 433行，在十字架上 cross_xAx = self._cross_xAx文件“ C：\ Users * \ AppData \ Local \ Continuum \ anaconda3 \ lib \ site-packages \ pptx \ chart \ axis.py”， _cross_xAx中的第512行 cross_axId = self._element.xpath（expr）[0] IndexError：列表索引超出范围

我认为问题在于类别轴内的日期时间值。因为如果我根据其他类型的对象（字符串，浮点或整数）创建该轴，则一切正常！

任何帮助将不胜感激！
