I am trying to make a google chart dashboard and tried the following code:

var temp3 = null ;
var longArray = ['Year','Positive','Negative','Neutral','Comments','Status','Score'];
var shortArrays = [], m, len;
var arrayOfArray = [];
var temp = listOfValues.split("-");

longArray.push(temp3[0]);

arrayOfArray.push(shortArrays[m]);

After executing this code I get table data clearly; but, it doesn't show the chart properly (I have used combo chart and Line chart). It is throwing the following error:
"Data column(s) for axis #0 cannot be of type string"
Can someone please tell how to solve this issue.
Thanks.
when you alert listOfValues you will get these values :
2010,84,65,45,facebook,bad,12345-2011,64,75,85,facebook,bad,2345-
Basically these are two rows in database which i have separated by a hyphen. Please let me know if you need further details.

Your data series must be type "number" in order to draw a chart (your x-axis data can be type "string"). Since you are spliting a string into an array, the array elements will all be strings. Assuming all of your data is numeric, you can replace this line:
longArray.push(temp3[0]);
with this:
longArray.push(parseFloat(temp3[0]));
or this, if your data is all integers:
longArray.push(parseInt(temp3[0], 10));
[Edit: more complete answer to deal with different datatypes]
There are two ways you can address this. The first way is to define your column data types up front:
var longArray = [
{label: 'Year', type: 'number'},
{label: 'Positive', type: 'number'},
{label: 'Negative', type: 'number'},
{label: 'Neutral', type: 'number'},
{label: 'Comments', type: 'string'},
{label: 'Status', type: 'string'},
{label: 'Score', type: 'number'}
];
You can also do some crude type detection when inputting your data:
for(var i=0; i<temp.length; i++){
temp2 = temp[i].split(',');
if(temp2.length == 7){
for(var j=0; j<temp2.length;j++){
// this does nothing except make temp2[j] into a 1-element array
// temp3[0] === temp2[j], since you split on ',' already
temp3 = temp2[j].split(',');
if (temp3[0] == parseInt(temp3[0])) {
longArray.push(parseInt(temp3[0]));
}
else if (temp3[0] == parseFloat(temp3[0])) {
longArray.push(parseFloat(temp3[0]));
}
else {
longArray.push(temp3[0]);
}
}
}
}
You can combine these two methods just in case something slips through. See them working here: http://jsfiddle.net/asgallant/xLKcx/
As an aside, I suggest cleaning up your code - you have a lot of spaghetti code in your section building the data array. Here's a simpler version: http://jsfiddle.net/asgallant/xLKcx/1/
