Hello All  
I am working on a window containing data reported from a water flow meter in an Easy Chart component. The meter reports back in GPM\*1000  
I would like to scale this back down to GPM for the y axis. I have tag historian enabled on the tag.

I cannot find the way to resize the values or the axis to fit this format.

Any help is greatly appreciated, thank you

The EasyChart doesn’t support that. You have to change the data itself. Normally that would be done by applying scaling to the OPC tag. Doesn’t help with your history, though.

Thank you. For others that may stumble on this, scaling: [Tag Scaling Properties - Ignition User Manual 8.0 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC80/Tag+Scaling+Properties)

Probably better to link to docs for a **supported** version of Ignition:
