Very Simple Qustion about binding

[Safak]

 Hi to all :

All I need to learn is : Is that possible to make chart of a log which comes with separate sheet and updates itself every lets say 30 sec.?
If yes , can you please provide a example ?
lets say my log has these information and keeping in document named  " try.json"  (this file updates itself ever 30 sec.)


 [ { "year": "2000", "sales": 200 }, 
  { "year": "2001", "sales": 450 }, 
  { "year": "2002", "sales": 300 }, 
  { "year": "2003", "sales": 125 }
]

Hi Safak,

You could achieve the described functionality using the DataViz refresh() method - this way you will be able to reload the data and repaint the chart in the needed interval. Please check this combined online example which illustrates similar functionality.

HI Nikolova , 

I already checked that example out  and also tired that reflesh() function. In that case my problem was this : 

I run my html(which has refresh button) file and created the graph it was cool , than I edited my try.json and changed some values and saved it .After this , I clicked on the refresh button to see new values but it didnt work ? What am I doing wrong?

Thanks for fast reply....

Hello Safak,

This scenario looks completely valid and I am not sure what may cause the problem in your application. Please make sure that you hook up the refresh() function of the chart to the refresh button. In case this is correctly implemented, could you please provide a full runnable project that could be examined in details? This way I will be able to assist you further.
