Automatic Updates

Time series are all about change. dataZoa's automatic updates recognize changes and propagate them wherever appropriate.

Data

When you drag-and-drop data series into dataZoa from other sites around the Web, we monitor for changes and make updates accordingly.
For sites with important and closely watched data release schedules, we sync up as quickly as the sites allow.
There are many nuances and details in the updating process, but generally speaking we check for changes everywhere at least once a day.

Despite all appearances, we do not have magic powers. When you have uploaded your own data you will need to keep it up to date by updating it or re-loading.
If you are officially responsible for some particular data, encourage your colleagues to follow it in dataZoa rather than making copies. No copies means no confusion.
Don't forget to preserve your series keys if you re-load your data. That's how your displays and calculations stay up to date.

When you update existing series in your account manually, the changes are fully propagated.
Series keys are naturally preserved.

Changes to series in your account that are shared with you, rather than owned by you, are fully propagated.

dataZoa displays are not static snapshots. If you embed a dataZoa display into a presentation, the presentation will show the up-to-the-moment state of things.
Whenever you view a dataZoa display, you are seeing the current state of the data, not a copy of how things were at the time it was created.
That said, dataZoa does not refresh displays that are currently on screen; the on-screen display stays put until you refresh it.
Make that presentation just once. As data changes, last month's presentation then automatically becomes this month's.
To archive a display at a particular point in time, hit the PDF button and store a snapshot.

dataZoa calculations work kind of like a world-scale spreadsheet. Change a number anywhere and everything that depends on it changes downstream, automatically.
Dependencies can get complicated and that's AOK. dataZoa keeps track of the multiple parent/child relations for you (yes, even non-traditional situations).
Whenever you view a calculated series, by itself or in a dataZoa display, you are seeing the current state of the data, not a copy of how things were at the time it was created.
When you change a calculation that other calculations depend on, that change flows right through as well.
