Invert value from sensor

[xZise]

Hi, I have multiple values which I want to display in a bar chart. Everything seems to work, except for that fact that one value is actually inverted/negated. Would it be possible to add an attribute to the entities object to invert one value?

One value for one particular moment of time?)))

Check this: #591
Probably what you need is a "-1" multiplier.

"multiplier" is not a function of mini-graph-card ?

[ildar170975]

Not sure if I understood your question.
Currently there is no multiplier option for mini-graph-card.

im in need of inverting my numbers and came across this post.
multiplying the entitiy value by -1 would be perfect but i dont find a function to do this as part of mini-graph-card.
i thought 'multiplier' was a suggested function, i didnt find that in the docs, or a way to perform this calc.
i didnt want to have to create a new entity for all the ones i need to apply a calculation change to.

Currently you have to create a template sensor.
