python-3.x - python-pptx 颜色图例未显示与图形相同的颜色

Question

这让我抓狂。

    chart_AllData = slideref.shapes.add_chart(XL_CHART_TYPE.BAR_STACKED_100, x, y, cx, cy, chart_data)

    chart = chart_AllData.chart        
    plot = chart.plots[0]
    pointCount = 0
    for answer in consolidatedAnswersList: # Looping over the answer codes
        print('answer: ', answer)
        catBar = plot.series[pointCount].points
        for cat in catBar: # Looping over the categories (= the declarations)
            fill = cat.format.fill
            fill.solid()
            colorString = ccpStatistics.gAnswerCodeColorDict.get(answer, 'FFFFFF')
            r = int(colorString[0]+colorString[1], 16)
            g = int(colorString[2]+colorString[3], 16)
            b = int(colorString[4]+colorString[5], 16)
            fill.fore_color.rgb = RGBColor(r , g , b)
            print('setting ', answer, ' to ', colorString)
        pointCount += 1

    print(ccpStatistics.gAnswerCodeColorDict)

    category_axis = chart.category_axis
    category_axis.minor_tick_mark = XL_TICK_MARK.OUTSIDE
    category_axis.tick_labels.font.italic = True
    category_axis.tick_labels.font.size = Pt(12)

    value_axis = chart.value_axis       
    value_axis.format.line.color.rgb = RGBColor(0 , 0 , 0)
    value_axis.tick_labels.font.size = Pt(int(thisPageDict.get('SCALEFONTSIZE', ['18'])[0]))
    value_axis.major_tick_mark = XL_TICK_MARK.OUTSIDE
    value_axis.has_major_gridlines = True
    value_axis.tick_labels.font.color.rgb = RGBColor(0,0,0)
    value_axis.major_tick_mark.number_format = '0.0"%"'

    chart.has_legend = True
    chart.legend.position = XL_LEGEND_POSITION.RIGHT
    chart.legend.include_in_layout = False # set to true
    chart.legend.font.color.rgb = RGBColor(0,0,0)
    chart.legend.font.size = Pt(int(thisPageDict.get('LEGENDSIZE', ['12'])[0]))

    plot.has_data_labels = True
    data_labels = plot.data_labels

    data_labels.position = XL_LABEL_POSITION.CENTER
    data_labels.font.size = Pt(int(thisPageDict.get('LEGENDSIZE', ['10'])[0]))
    data_labels.font.color.rgb = RGBColor(0x00, 0x00, 0x00)

ccpStatistics.gAnswerCodeColorDict的内容如下:

{'oaq_NoAnswer': 'DCDCDC', 'maq_NoAnswer': 'DCDCDC', 'Answer code': 'Answer code color', '1': 'FF0000', '2': 'FF6600', '3': 'FFC301', '4': '00B050', 'OK': '00B050', 'NOK': 'FF0000', 'NA': '333333', 'NEU': 'FF00FF', 'maq': '3A87AD', 'dq': '660000', 'txta': '660000', 'nq': '660000'}

现在，图表根据系列中的设置正确着色......图例中的系列名称也可以......但图例的颜色与条形图的颜色不对应。

注意，类似的代码似乎在其他方法中也能正常工作。我现在无计可施了。

尝试在系列级别而不是在单个点级别设置颜色。

fill = series.format.fill
fill.solid()
fill.fore_color.rgb = RGBColor(r, g, b)
