I have a graphical counter that is fed by JSON what I wanted to err generate dynamically houses ie having a number of elements stipulated by a variable.

Example of what I tried to do:

<script type="text/javascript">
// Get the context of the canvas element we want to select
var ctx = document.getElementById("piechart").getContext("2d");
var data = [
while(i=2)
{
{
    value: <?print $valor;?>,
    color:"#F7464A",
    highlight: "#FF5A5E",
    label: "Red"
},
i++;
}


];

var options = {
  animateScale: true
};

var myNewChart = new Chart(ctx).Pie(data,options);

php javascript

An example next to yours that should work:

<script type="text/javascript">
// Get the context of the canvas element we want to select
var ctx = document.getElementById("piechart").getContext("2d");
var data = [];
var i = 0;
while(i <= 2)
{
    data.push({
        value: <?print $valor;?>,
        color:"#F7464A",
        highlight: "#FF5A5E",
        label: "Red"
    });
    i++;
}

var options = {
  animateScale: true
};

var myNewChart = new Chart(ctx).Pie(data,options);
</script>

It worked. But I'm not able to pass value from an array of PHP.

 <script type="text/javascript">
