I found that it might be useful if Range node had option to set input range values dynamically. Why? For example I have a set of numeric data and it changes daily. So min and max are different for each day. For graphical representation I range that data into proper scale. But data can have anomali…

Probably easier to just write it as a function :slight_smile:

I already did that :slight_smile: But I just found that it might be useful for other cases too. Not only mine. And that other -- Node-RED and less coding -- thing :wink:

Our default behaviour on nodes is that a value can only be overridden if the field is left blank - at which point you then need to pass in the override value on every msg. - and in this case you would need 4 extra properties - minIn maxIn minOut maxOut etc... which just makes the node info messy, an…

Well comparing with Chart node to show historic data .... OK they are different enough things for sure Let it be :slight_smile:

I realize this is an old topic, but for me too it would be very helpful to be able to use a numeric input to feed the input range from and to fields. I'm building yet another plant watering system and I'm using the range node to reverse and calibrate a capacitive moisture sensor (1600, 3500, 100, 0…

Thanks for the link, I'm afraid I'm not to hot in javascript. Would that be a variation of: https://gist.github.com/AugustMiller/85b54d49493bb71ba81e#file-map-js map.js const mapNumber = (number, in_min, in_max, out_min, out_max) => { return (number - in_min) * (out_max - out_min) / (in_…

This is pseudo code to explain how this can be used in function node. Do not expect it to work out of box. You will need to make many adjustments before it actually does the trick. But basics here. var value = msg.payload;//value to be ranged //range limits var inputrange = msg.inputrange || [0,10…

All that range node does can be achieved with function also. It can be then adjusted and optimized by your specific needs.
