BAR Chart Block on dashboard shows “no data available” for Last Received Data Point if value is 0
For instance I am using a BAR Chart block to show the current RPM (last data point received) as a quick guide of the state of a collection of engines.
When they are not running it’s showing “No data returned” even though there are data points. They are just 0.
If I pick some other property that has either a negative or positive value the last data point is shown.
Looking at the last data point logged it definately has an RPM data point with a value of 0.
If I add a second data point to the graph that has a non zero value the the graph also shows data.
So it looks like a corner case where the BAR Chart block is treating 0 as no data. Rather than showing 0 if that the only data to show has a value of 0.
Which I think is different to “no data available”
