Openpyxl设置图表标题
在使用openpyxl绘制图表时,有时候我们需要设置图表的标题,包括标题的内容和字体样式。以下是根据搜索结果得到的方法:
要修改openpyxl图表的标题内容,首先需要创建一个图表对象,然后设置其`title`属性。例如,创建一个饼状图,并将其标题设置为'饼图',可以使用以下代码:
```python
from
openpyxl
import
Workbook
from
openpyxl.chart
import
PieChart
wb
=
Workbook()
ws
=
wb.active
pie
=
PieChart()
pie.title
=
'饼图'
```
要修改openpyxl图表标题的字体,我们需要利用`openpyxl.chart.text.RichText`类来创建一个富文本对象,然后设置其字体属性。例如,将图表标题的字体大小设置为35pt,可以使用以下代码:
```python
from
openpyxl
import
Workbook
from
openpyxl.chart
import
AreaChart
from
openpyxl.styles
import
Font
from
openpyxl.chart.text
import
RichText
wb
=
Workbook()
ws
=
wb.active
rows
=
[['Number',
'Batch1',
'Batch2'],
[2,
40,
30],
[3,
40,
25],
[4,
50,
30],
[5,
30,
10],
[6,
25,
5],
[7,
50,
10],]
for
row
in
rows:
ws.append(row)
chart
=
AreaChart()
chart.title
=
RichText(p=[Paragraph(pPr=pp,
endParaRPr=cp)
for
pp,
cp
in
[
(ParagraphProperties(defRPr=CharacterProperties(latin=Font(typeface='Arial',
sz=35))),
CharacterProperties(latin=Font(typeface='Arial',
sz=35)))
]])
chart.x_axis.title
=
RichText(p=[Paragraph(pPr=pp,
endParaRPr=cp)
for
pp,
cp
in
[
(ParagraphProperties(defRPr=CharacterProperties(latin=Font(typeface='Arial',
sz=10))),
CharacterProperties(latin=Font(typeface='Arial',
sz=10)))
]])
chart.y_axis.title
=
RichText(p=[Paragraph(pPr=pp,
endParaRPr=cp)
for
pp,
cp
in
[
(ParagraphProperties(defRPr=CharacterProperties(latin=Font(typeface='Arial',
sz=10))),
CharacterProperties(latin=Font(typeface='Arial',
sz=10)))
]])
```
以上两种方法都可以实现openpyxl图表标题的设置,你可以根据实际需求选择合适的方法。
