Using openpyxl version 2.5.0b2 inside a docker container on a mac, I have a line chart that is dropped from the output when the title of the chart is dynamically linked to a cell through a formula.
I have attached two example files, one with the undesired behavior and one without. test_chart_with_formula.xlsx is the version of the chart with the formula in the title. test_chart_without_formula.xlsx is the version of the chart without the formula in the title.
The following code reproduces the issue. It round trips each file by loading it in and then writing it out:
import openpyxl print(openpyxl.__version__) #'2.5.0b2' wb_with_formula = openpyxl.load_workbook("/data/test_chart_with_formula.xlsx") wb_with_formula.save("/data/test_chart_with_formula_output.xlsx") wb_without_formula = openpyxl.load_workbook("/data/test_chart_without_formula.xlsx") wb_without_formula.save("/data/test_chart_without_formula_output.xlsx")
test_chart_without_formula_output.xlsx will open as expected, with the chart still there as it should be.
When I open test_chart_with_formula_output.xlsx, a dialog box will appear:
If I click "Open and repair", then another dialog box pops up saying: "Excel repaired or removed unreadable content from this workbook. Do you want to view the log file to see what changed, or delete it?" I chose to view the log file, and I've attached it to this issue as well -- it is file Repair Result to test_chart_with_formula_output0.xml.
After all is said and done, the chart is not present on the final file once it is fully opened.
