We would like to move on from phpdocx v. 7.0 to v. 7.5 and have been lately converting chart data to the new structure required by the 7.5 version. But we have problems with addChart "showTable" parameter. It just does not work. Setting it to true (true, 1 or '1') makes no difference. We have also tried examples with the same results. There was no problem with the 7.0 version but now the table of chart data does not appear under any bar chart. Weirdly enough, one can easily open a resulting docx file and manually set the option to true for any chart.
Hope that someone could help us with this issue.
