Steps to Reproduce:
1. Create .xlsx file using python. for example:

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

wb = Workbook()
ws = wb.active
for i in range(10):
    ws.append([i])

# drawing a graph
values = Reference(ws, min_col=1, min_row=1, max_col=1, max_row=10)
chart = BarChart()
ws.add_chart(chart, "A15")
chart.title = "Chart"

chart.add_data(values)

wb.save("Barchart.xlsx")
