Getting Drawing error

Hello, getting - Error Drawing Graph: Error: unkown option ‘–left-axis-format’,
on the device graphs which are related to device health, temperature, voltages.

I think it got broken after some of the updates, can’t say after exactly which one.

i think its due to the older rrdtool version on my system.

maybe it possible to disable ‘–left-axis-format’ option ? or better to update the rrdtool on my box ?

I’d update rrdtool, 1.4.8 is 12 years old.
