MQTT Sensor Floating point rounding problems

Configuration
1

I’m trying to display a graph of an MQTT sensor but the GRAPH entity keeps rounding down numbers like “0.41” to “0”

How do I force the graph to display numbers to two decimals?

I solved my own problem. HA does not like floating point numbers without a leading zero. By changing my MQTT sensor to “0.41” HA displays the number as “0.41”. If the sensor outputs “.41” HA rounds the number to “0”
