使用Openpyxl更新Excel模板导致图表不再显示数据表

Question

I am updating the data behind a chart using Openpyxl. When I update the data and save the template as a new file, the excel chart that is created from that data seems to lose its formatting, specifically the data table attached.

I have already tried checking and unchecking "Properties follow chart data point for current / all new workbook(s).

I expect the chart to have the same format as the original excel template. In this case, the lines on the graph are updated, but the data table underneath the graph disappears.

Below is my openpyxl snippet, though it probably won't be useful. All I am doing is updating cell values in a loop.

    for i in range(0, 12):
        ws_S_EPE['D{}'.format(i+36)] = pr['Energy'][i] / 1000
        ws_S_EPE['E{}'.format(i+36)] = pr['pr'][i]
        ws_S_EPE['F{}'.format(i+36)] = pr_tc['pr_tc'][i]

Here are picture of the graph in the template and the file created from the template.

I have similiar issues with openpyxl. After saving a file the chart format is changed, and text boxes are deleted (see link).

truncate, copy from one xlsx and paste to another with openpyxl: messes up all text boxes, charts etc

No hints here?

PS: Ah, I see, preserving charts in existing files hasn't been included yet in openpyxl. Pity!
