Using openpyxl, the charts inserted into my worksheet have a border on them. Is there any way to set the style of the chart (pie/bar) to either via the styles.Style/styles.bord
This isn't easy but should be possible. You will need to work through the XML source of a suitably formatted sample chart and see which particular variables need setting or changing. openpyxl implements the complete chart API but this unfortunately very complicated.
