Openpyxl - Creating a chart on a different sheet

Question

I have been using Openpyxl to transfer pandas dataframes to an Excel file. I have to work utilising a template file given to me by work.

Because I cannot modify much in the 'printable' sheets, I created a worksheet at the end of the workbook where I added all of my dataframes. Now I must plot them and put the various charts in different sheets.

My question is, can I use openpyxl methods to create charts on sheets that are not active? All of the data/labels for the charts are on one sheet, and I want to make the graphs for different sheets. I have searched all of the documentation and this site and cannot find the answer.

An alternative question is, can I copy charts from one sheet to another within the same file? and if so, how can I do it?

Thanks!

You can create charts on non-active sheets. Instead of using active you can use fixed references to each sheet, eg

wb = Workbook()
ws_data = wb['Data']

I always use worksheets like this ( Explicit is better than implicit ).

Example:

from openpyxl import Workbook
from openpyxl.chart import BarChart, Reference, Series

wb = Workbook()
wb.create_sheet('Data')

ws_data = wb['Data']
for i in range(10):
    ws_data.append([i])

sheetlist = ['Test1', 'Test2', 'Test3']

for w in sheetlist:
    wb.create_sheet(w)

for s in sheetlist:

    values = Reference(ws_data, min_col=1, min_row=1, max_col=1, max_row=10)
    chart = BarChart()
    chart.add_data(values)

    ws = wb[s]
    ws.add_chart(chart, "B5")

wb.save("SampleChart.xlsx")
