Chartology scale question

[allstock]

Why is the recent price action in every chart always blown up regardless of scale settings compared to past price action?

....and then say after some time, regardless of which chart, any given set of price action turns into smaller size compared to the most recent and update price action(staying in the same chart). Does this happen solely due to logarithm? because I see it in linear as well.

I've been wondering about this for a very long time and I think I know the answer, but can't put in a intelligent manner.

Could you please provide an example, I'm struggling to understand what you mean by 'blown up'?

A perfect example is if you look at the sp futures chart on FINVIZ.COM. You'll notice what was once the most recent price action that changes to the past the logarithmic attributes takes affect. But the most present price action always seems to be blown up comparative to past data.
