在python-pptx中,可以使用chart
对象来设置散点图的字体大小、轴值和轴标题。下面是设置字体大小、轴值和轴标题的步骤:
from pptx import Presentation
from pptx.enum.chart import XL_CHART_TYPE
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])
chart = slide.shapes.add_chart(
XL_CHART_TYPE.XY_SCATTER, x, y, width, height, chart_data
).chart
其中,x
和y
是散点图的位置,width
和height
是散点图的宽度和高度,chart_data
是散点图的数据。
chart.has_title = True
chart.chart_title.text_frame.text = "散点图标题"
chart.chart_title.text_frame.paragraphs[0].runs[0].font.size = Pt(18)
通过chart_title.text_frame.text
设置标题文本,通过font.size
设置字体大小。
category_axis = chart.category_axis
category_axis.has_title = True
category_axis.axis_title.text_frame.text = "X轴标题"
category_axis.axis_title.text_frame.paragraphs[0].runs[0].font.size = Pt(14)
category_axis.tick_labels.font.size = Pt(12)
value_axis = chart.value_axis
value_axis.has_title = True
value_axis.axis_title.text_frame.text = "Y轴标题"
value_axis.axis_title.text_frame.paragraphs[0].runs[0].font.size = Pt(14)
value_axis.tick_labels.font.size = Pt(12)
通过category_axis.axis_title.text_frame.text
设置X轴标题文本,通过value_axis.axis_title.text_frame.text
设置Y轴标题文本,通过font.size
设置字体大小。
完整的代码示例:
from pptx import Presentation
from pptx.enum.chart import XL_CHART_TYPE
from pptx.util import Pt
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])
x = 100
y = 100
width = 500
height = 300
chart_data = [
("Series 1", ((1, 1), (2, 3), (3, 2))),
("Series 2", ((1, 2), (2, 1), (3, 3))),
("Series 3", ((1, 3), (2, 2), (3, 1))),
]
chart = slide.shapes.add_chart(
XL_CHART_TYPE.XY_SCATTER, x, y, width, height, chart_data
).chart
chart.has_title = True
chart.chart_title.text_frame.text = "散点图标题"
chart.chart_title.text_frame.paragraphs[0].runs[0].font.size = Pt(18)
category_axis = chart.category_axis
category_axis.has_title = True
category_axis.axis_title.text_frame.text = "X轴标题"
category_axis.axis_title.text_frame.paragraphs[0].runs[0].font.size = Pt(14)
category_axis.tick_labels.font.size = Pt(12)
value_axis = chart.value_axis
value_axis.has_title = True
value_axis.axis_title.text_frame.text = "Y轴标题"
value_axis.axis_title.text_frame.paragraphs[0].runs[0].font.size = Pt(14)
value_axis.tick_labels.font.size = Pt(12)
prs.save("scatter_chart.pptx")
