Chart trying to plot extraneous fields, how to stop this?

Post Posted: Thu Oct 27, 2011 7:05 am

I am continuing with my charting adventures, and would like to know - how does one prevent a chart from trying to plot fields in the data that exist, but are not defined in the series that I wish to show?

I am carrying around this data for the sake of creating informative tool tips and labels, but instead the chart is plotting them.

Thank you,
Brett

Hi Brett,
You can use the seriesKeys attribute to limit the series items.
http://yuilibrary.com/yui/docs/api/classes/ChartBase.html#attr_seriesKeys

If specified, only the key values in the array will be included in the axes and series.

Code:
var mychart = new Y.Chart({
    dataProvider: myDataProvider,
    seriesKeys: [ "hi", "lo", "open", "close"],
    ...
});


Thanks,
Tripp

Thank you, Tripp.

I am dynamically building up this seriesKeys array, and I can confirm that it is only passing in the fields that I wish to be show.

I will try to come up with an example.

Nope, I was wrong. Thanks for making me double check. :)
