[英]Python, pptx to change line color in line chart
Created a line chart using pptx. 使用pptx创建折线图。 I want to change the line color to red.
我想将线条颜色更改为红色。
Added the "fill" and indicated the RGBColor (255, 0, 0) but it's still blue. 添加了“填充”并指示RGBColor(255、0、0),但仍为蓝色。
How can I change it to red? 如何将其更改为红色? Thank you.
谢谢。
from pptx import Presentation
from pptx.chart.data import ChartData
from pptx.enum.chart import XL_CHART_TYPE
from pptx.util import Inches
from pptx.dml.color import RGBColor
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])
chart_data = ChartData()
chart_data.categories = ["2014", "2015", "2016", "2017", "2018"]
chart_data.add_series('Series 1', ("50", "45", "46", "52", "56"))
x, y, cx, cy = Inches(0.5), Inches(2), Inches(8), Inches(3.5)
graphic_frame = slide.shapes.add_chart(XL_CHART_TYPE.LINE, x, y, cx, cy, chart_data)
chart = graphic_frame.chart
plot = chart.plots[0]
series = plot.series[0]
fill = series.format.fill
fill.solid()
fill.fore_color.rgb = RGBColor(255, 0, 0)
prs.save('c:\\My Documents\\line chart.pptx')
Use series.format.line
instead of series.format.fill
: 使用
series.format.line
而不是series.format.fill

line = series.format.line
line.color.rgb = RGBColor(255, 0, 0)
The LineFormat
object can also be used to set line style (dashed, dotted, etc.) and line width: https://python-pptx.readthedocs.io/en/latest/api/dml.html#pptx.dml.line.LineFormat LineFormat
对象还可以用于设置线型(虚线,点线等)和线宽: https : //python-pptx.readthedocs.io/en/latest/api/dml.html#pptx.dml.line .LineFormat
The lines in a line chart each have a line, but not a fill (as would say a bar-chart). 折线图中的每条线都有一条线,但没有填充线(可以说是条形图)。 In a bar-chart, you can set both line and fill, separately.
在条形图中,可以分别设置线条和填充。
