In Calc, I am creating an XY diagram with two series of data. By default, the first data series is shown as blue squares and the second data series as red diamonds. However, I would like to change these colours to something that does not need colour printing, but is still easily distinguishable. In Microsoft Excel, I would be able to change the colours of both the edge and the filling of the data points. In this way, I could for instance make the square black and the diamong white with black border.
Is something like this possible in Calc?
I am using LibreOffice version 18.104.22.168.
