Hi evryone 
I'm using the "aggregation based" visualisation on my Dashboard, specifically the Vertical bar chart and I have something very strange which is happening: I'm using the "Show values on chart" button on the right panel settings window, it usually worked well, but this time it shows "zero" values when it's not. I did some screenshot to show you.
On this one it shows "0" but you can see (on the small black window) it should be "4" :
On this one it should be "1" instead of "0":
For all the "0" in the chart this is the same thing.
Any idea of what could it be?
Thanks in advance
