Hey Paulo,
Sorry for the long reply! I don't have an example I can easily strip out for you, but I can describe one!
I'm doing a simple graph for our SaaS solution, and it counts the number of users per tenant every night using a simple trigger. It fills an entry into this table

After 180 days I have 180 of those, and the graphs looks like above. From my understanding the datetime x-axis would not write all those labels out explicitly, but only take a few to show people where about in time you are.
The other issue is that the current x-axis that is not time aware doesn't scale correctly if you do not have a daily value:

As you can see the first 50% of the graph is just April, then 2 months until We're in June, then suddenly we're in September (so 50% of the graph is 6 months, and the first half is 3 days). I believe the time axis would fix this issue as well - admittedly a side issue, but still related.
