datasource for line chart instead of datatable

[Jishnu U]

Hi

Im working on a website that uses google Line charts. Im receiving data from SQL table using a library function which we made that returns data as string array. 

How can I use this array to plot in line chart.

I tried using 

 var data = google.visualization.arrayToDataTable(ar);

but as all column and row are string I cant get the plot.

Does anyone has any solution to it??

If your string is formatted as a javascript array, you can try parsing it as JSON:

var data = google.visualization.arrayToDataTable(JSON.parse(ar));

im sorry .. I dont know what a java script formatted array is. but anyways what im getting from the SQL library is normal string array (as far as I know).

one column of time stamp and one column of sensor data.

can i do something with it?

Give what I posted a try anyway.  If it doesn't work, post an example of the value of ar and I'll take a look.
