Show the difference between min and max in a plot

[kede...@gmail.com]

Hi,

in skin.conf / [ImageGenerator] is there a simple way to plot the difference between intemp.max and intemp.min?

Reason: I've got new windows (that doesn't mean the "famous" OS but the optical equipment that let one look through thick walls from inside to outside) and I want to know whether there are any results in isolation.

Kind regards

Klaus

Not sure what you're looking for. What does intemp.max and intemp.min represent? The max and min for a day? Compared to last year? Something else?

Hi tom,

I can plot intemp.max and intemp.min in a diagram. But how to plot "intemp.max-intemp.min" as a curve?

kind regards

I don't know what intemp.min and intemp.max mean (there is no such notation in weewx). The "min" and "max" imply an aggregation, but over what? 

As an example, maybe you're aggregating plots over 3 hours, and want to display the difference between minimum and maximum interior temperature over that 3 hours? Something else?

We can't guess your intentions.
