I am drawing an excel scatter chart with python and xlsx writer and use custom data labels for one series. But I can not set the position of the custom labels like I can with the default labels. If I set the position of the custom labels they dont change in the chart. In the debugger or if I check their label options in excel itself I can see the changed position values, but they are not applied in the drawing. At default the custom labels seem to bet set at right. I want them on top but I cant get this. The code is like that:
chart.add_series( .., 'data_labels': {'custom': my_custom_labels, 'position': 'above'})
But the changes wont appy to the chart. I also found i can set the default label position (label_position_default) in the chart object (which is right on default) but it wont change the custom label position either. Anyone has an idea how to get a custom data label on top position?
