Using the bar-chart-data node, it will display the proper values if I want a max value shown, along with sum and average, but the chart will not display anything if you want to show the minimum value.
I'm feeding it just a simple battery voltage value (ie 12.54) every 5 seconds or so when the data comes in from a modbus device and I want to chart the daily low values.
If I set bar-chart-value to max just after midnight, the new value will pop up on the chart for the day, and then if I set it to follow the minimum, it will properly, but not if its minimum right at midnight.
Any one else seeing this issue, or have a fix for it?
Thanks in advance.
