Hi all,  
can you please help me to switch from Line- to Bar-Chart ?

I have two msg.Objects msg1 and msg2 with individual topic and payloads.  
If I insert them into a line-chart it works perfectly fine and I see two lines in the chart.  
If I change chart type from line to bar all I see is one big bar, showing the last transfered value only ☹

No matter what I try ... I am unable to feed the bar chart in a reasonable way ☹

BR
