Update Values which are smaller than x

Quick question on this: I’m using Chronograf 1.10.0 on influxDB 1.8 and I’m getting the error error calling function "to": function "to" is not implemented. Here I read that Flux in InfluxDB 1.x is read-only, so I am not able to write data back to InfluxDB. Is this true?

If yes, what’s the alternative? Using influxQL instead?
