Visualization of Healthcare Sensor Data via CSV File in HTML?

[Lee Deneault]

Hi Group!

I would like to use Google Visualization / Developers Tools to draw a stack plot of a multi-parameter CSV File using HTML.

An example of the CSV File Format is attached to this Post.

As you will see, the rows are in 5 second increments...

Ideally, I would like like to be able to "draw" the newly "acquired" rows in real-time but, for right now, I would just like to see the data in a static fashion.

I used an on-line converter to create a JSON file of the above CSV File, if that is a better way to go and the result of this conversion is also attached to this Post.

Needless to say, any and all advise would be greatly appreciated!

Many thanks, in advance, for your time and consideration!

Best Regards,

LEE

PS - I have always been so very impressed with how easy Google Developer Tools were to use, up until now!

Successfully drawn Google Developer Charts are so "beautiful" and "stunning" that I truly hate to use anything else but, I am afraid that doing the above is either not as straight forward as I had hoped or I am just not "getting it" quite yet...! My money is on the latter...!     

  

Seriously, thanks again...!

Hi Lee,

Google Charts will work with JSON-like format if it is formatted as expected, as documented here:  https://developers.google.com/chart/interactive/docs/datatables_dataviews#javascriptliteral

If you can provide the data via a Google spreadsheet, the correct conversion is done for you. See  https://developers.google.com/chart/interactive/docs/spreadsheets

Realtime updating of the chart basically requires multiple draw() calls with the new data.  If you wrap your chart in a ChartWrapper, then you can use the setRefreshInterval() method to automatically get new data and draw it:  https://developers.google.com/chart/interactive/docs/reference#methods_4
