How can you get any granularity whatsoever from trading platforms like TD’s thinkorswim?

Look at the difference between TD's thinkorswim and Robinhood, both set to last week:

The Robinhood graph is insanely better – so much more detail and so much easier to make judgments about.

I've tried several trading platforms and they all seem to have the same issue.

How can I get real, actual granularity of at least Robinhood quality out of a platform like TD's thinkorswim?
