更改chartSpace图形属性

Question

我想更改图表空间的图形属性，特别是与图表空间边框相对应的图形属性。

为了理解代码，我需要添加/修改以下方法：

'How to set up the Graphical Properties of Chart Area using openpyxl'

代码如下：

from openpyxl import Workbook
from openpyxl.chart import (
        ScatterChart,
        Reference,
        Series,
)
from openpyxl.chart.shapes import GraphicalProperties
from openpyxl.drawing.colors import ColorChoice
from openpyxl.drawing.line import LineProperties

wb = Workbook()
ws = wb.active

rows = [
        ["Size", "Batch 1", "Batch 2"],
        [2, 40, 30],
        [3, 40, 25],
        [4, 50, 30],
        [5, 30, 25],
        [6, 25, 35],
        [7, 20, 40],
]

for row in rows:
    ws.append(row)

chart = ScatterChart()

# ChartSpace graphical properties
colori = ColorChoice(srgbClr = "FF0000")
linprop = LineProperties(solidFill = colori)
prop = GraphicalProperties(ln = linprop)
chart.graphical_properties = prop

chart.x_axis.title = "Size"
chart.y_axis.title = "Percentage"

xvalues = Reference(ws, min_col = 1, min_row = 2, max_row = 7)
for i in range(2, 4):
    values = Reference(ws, min_col = i, min_row = 1, max_row = 7)
    series = Series(values, xvalues, title_from_data = True)
    chart.series.append(series)

ws.add_chart(chart, "A10")

wb.save("Example.xlsx")

但是，上述代码中的下一行似乎对图表没有影响。

colori = ColorChoice(srgbClr = "FF0000")
linprop = LineProperties(solidFill = colori)
prop = GraphicalProperties(ln = lineprop)
chart.graphical_properties = pro

是否可以为图表空间指定图形属性？
