Infochart Combination chart css-how to hide data lables for line only

Hi

I am trying to hide data labels related to line on my infochart(DS1.6).

I would like to have data labels for bars only. I tried to search for a proper css class with IE F12. I tried to use following code, but no luck:

.DPInfochart svg.v-m-root g.v-m-main g.v-m-plot g g.v-plot-main g.v-datalabel-group g.v-datalabel v-morphable-label text

{

visibility:hidden !important;

}

.DPInfochart g.v-markers g.v-datashapesgroup, g.v-m-datalabel g.v-datalabel text

{

visibility:hidden !important;

}

Any of you was able to achieve such thing with with CSS? I haven't found similar case on this forum.
