Hello everyone, I'm new here.
I've been working with prototype and plotr for about a month now, off
and on, and I have pretty much hit the wall on using the data returned
by Ajax.Request.
I'm using some php code to return a string:
{'foo': [[0,0.0865334429075127], [1,0.0828179861705063],
[2,0.0828173042602942], [3,0.0841707718624196]]}
But I keep getting an error: "item.pluck is not a function" on line
857 of plotr_uncompressed.js
Here is the code I'm using to grab the data into a javascript
variable:
var graphData = "";
var url = "foobar.php";
function generateGraphData(dataRange,dataUrl) {
new Ajax.Request(url, {
method: 'get',
parameters: {dR:dataRange,dU:dataUrl},
onLoading: function() {
// change this to a loading image/html
$(dataRange).innerHTML="loading...";
},
onComplete: function(request) {
if(request.status != 200) {
// change this to a pleasant error message
$(dataRange).innerHTML="unavailable...";
} else {
graphData = request.responseText;
$(dataRange).innerHTML = graphData;
}
},
onFailure: function() {
notice.update("hrm, something went wrong...");
}
});
}
And here is the code I'm using to try to load the data into the graph:
function updateChart(chartName) {
var newOptions = {
padding: {left: 30, right: 0, top: 10, bottom: 30},
backgroundColor: '#f2f2f2',
shouldFill: false,
colorScheme: 'blue',
yNumberOfTicks: 2,
xTicks: [
{v:5, label:'jan'},
]
};
document.getElementById('weekdiv').innerHTML = '<div><canvas
id="newchart"
height="250" width="700"></canvas></div>';
var weekLine = new Plotr.LineChart('newchart',newOptions);
//weekLine.addDataset(dataset2);
weekLine.addDataset(graphData);
weekLine.render();
}
As you can see in the last bit of code, I've commented out the line:
"weekLine.addDataset(dataset2)". dataset2 is an array defined in
javascript on this page, that is identical to the string that is being
passed to the page from the php script.
Any help would be greatly appreciated!!
