假设我们有以下代码:
from openpyxl import Workbook
wb = Workbook()
ws = wb.active
for row in range(1,10):
value = ws.cell(row=row,column=1).value = row+5
for row in range(1,10):
value2 = ws.cell(row=row,column=2).value = row
wb.save("SampleChart.xlsx")
from openpyxl.charts import Reference, Series,LineChart
values = Reference(ws, (1, 1), (9, 1))
series = Series(values, title="First series of values")
chart = LineChart()
chart.append(series)
chart.drawing.name = 'This is my chart'
ws.add_chart(chart)
wb.save("SampleChart.xlsx")
如何将第二列的值绘制到相同的折线图中? (并添加图例)?
解决方法:
我稍微重新排列了代码,以便在创建系列之前声明图表及其属性.然后,只需在第二个值范围上重复系列创建即可.据我所知,除非我误解了这个问题,否则Excel将自动创建图例.
from openpyxl import Workbook
wb = Workbook()
ws = wb.active
for row in range(1,10):
value = ws.cell(row=row,column=1).value = row+5
for row in range(1,10):
value2 = ws.cell(row=row,column=2).value = row
wb.save("SampleChart.xlsx")
from openpyxl.charts import Reference, Series,LineChart
# setup the chart
chart = LineChart()
chart.drawing.name = 'This is my chart'
# setup and append the first series
values = Reference(ws, (1, 1), (9, 1))
series = Series(values, title="First series of values")
chart.append(series)
# setup and append the second series
values = Reference(ws, (1, 2), (9, 2))
series = Series(values, title="Second series of values")
chart.append(series)
ws.add_chart(chart)
wb.save("SampleChart.xlsx")
