YUI Chart Series xData

Post Posted: Tue Jan 08, 2013 11:10 pm

Hi,

I have plotted a chart with dates in the X-axis and usercount on the Y-axix

I am able to get Series yData(User Count) by using below script
Code:
ydata = series.get("yData");



But I cannot find a way to get xData(Dates) for a series as below script is returning Indexno not dates
Code:
xdata = series.get("xData");



Below is the preview of my script. Line 7 is returning incorrect value.
Code:
sc = mychart.get("seriesCollection");
for(; i < sc.length; ++i)
    {
        series = sc[i];
        ydata = series.get("yData"); // returning correct value

        xdata = series.get("xData"); // returning incorrect value       
    }



Can you please tell me the correct way to get xData.


Thanks

The Category axis returns an array of indices for getDataByKey (which is used to define the series' xData/yData attributes). I have filed a ticket here. For now, you can use the workaround that I've written below.
Thanks,
Tripp
Code:
var i,
    sc = mychart.get("seriesCollection"),
    len = sc.length,
    isVertical = mychart.get("direction") === "vertical",
    categoryKey = mychart.get("categoryKey");
for(i = 0; i < len; ++i) {
    series = sc[i];
    if(isVertical) {
        ydata = series.get("yAxis").get("keys")[categoryKey];
        xdata = series.get("xData");       
    } else {
        ydata = series.get("yData");
        xdata = series.get("xAxis").get("keys")[categoryKey];
    }
}
