VizFrame chart combined properties

Hi everyone,

i'm using the VizFrame Combination-chart (sap.viz.ui5.Combination) to display some values. I tried to delete the markers (like i already did here with the line-graph), but the following code does not work.

plotArea: {    marker:{    visible : false    },
},

I also tried to make the bars a little bit thicker, but i can't find any documentation of the VizFrame-properties. It would be great if someone can give me a hint how to make these changes. Here is a screenshot of my actual chart:

Thanks and Regards,

Andreas
