>Anything will blow off the charts if you have the wrong scale.
>I feel like the responses to my comment do not understand what a scale is or what it means for something to go off it.
Readers understand the comment and understand what a scale is.
HN readers are notoriously critical of comments that don't add substantively to the discussion. Language is often used in ways that extend beyond the direct literal meaning of the words. and maximally pedantic interpretations ceased to be interesting a long time ago for most HN readers.
Also, in practice, chart scales and scale heights are generally an implicit measure of historical data range and variability, so if something blows past the top of the chart, even in a maximally literal interpretation, that is commonly a sign that something significant has happened in the signal being charted.
