Add remove fields from chart
How i can dynamically add and remove fields from a chart.
I want to start with a chart without any fields only y axis value. And based on the json data pulled i will populate the fields.
I got a very large data set and want to provide the users ability to select the data points. Mostly for comparison.
It may be safer to remove the chart and add it again.
i got a large set of data and want to show 6 out of 60 series at one time.
i can plot all but that will be messy.
i can turn that on off as well
what i want is that i should be able to define the fields while js. May be add then and remove then in Ext.chat.ChartPanel and render the charts.
The other approach is to pull the js through a php script but i would love to do all through js only.
