this is my code

var googleChartObj = [];

var xValues = ['3', '4', '9', '10']

if (xValues.length > 20) {
    xValues = xValues.slice(-20);
} else {
    xValues = xValues;
}

for (var i = 0; i < xValues.length; i++) {
    googleChartObj.push([i, xValues[i]]);
}

console.log("googleChartObj",  googleChartObj);

and this is the result

googleChartObj [ [ 0, '3' ], [ 1, '4' ], [ 2, '9' ], [ 3, '10' ] ]

but I want to convert like that

googleChartObj [ [ 0, 3 ], [ 1, 4 ], [ 2, 9 ], [ 3, 10 ] ]

To convert a string into a number there is parseInt function in javascript.

So all you need to do is while pushing the index and value convert the value to integer

googleChartObj.push([i, parseInt(xValues[i])]);

Here's the full code:

var googleChartObj = [];

var xValues = ['3', '4', '9', '10']

if (xValues.length > 20) {
    xValues = xValues.slice(-20);
} else {
    xValues = xValues;
}

for (var i = 0; i < xValues.length; i++) {

    googleChartObj.push([i, parseInt(xValues[i])]);
}

console.log("googleChartObj",  googleChartObj);
