Unanswered: adding a field or yield to the series dynamically so that the chart is updated
i want to change/update my chart by adding new fields to the series/data.
i tried to use chart.store.loadData() and passed the new data fields into store. but this didn't work as the series.items/yfields still has the old item counts.
i also tried to add new series to chart by using chart.initializeSeries(seriesData) but this still does't work
i am still looking for a good way to add fields/data to store n series dynamicaly so that i don't have to initiate ext.chart every time i want to change the data fields.
just to give u an overview of what i am trying to do is like at first create a chart with 5 data fields n then have a button on whose click i add n new field/data added to chart, but i don't want to do new Ext.cahrt every time.
chart.redraw() won't works when we do a redraw initialize series is called for each series where the old are the existing series with old data from the store are present and thus i does not allow to add a new field in the chart.
Note: i dont want to add a new year in the chart like suppose i have 2008, 2009 and then add 2010 but
i want to add new data to the existing field like if 2008 has 3 data i want to dynamically add the fourth data to the 2008, 2009, and 2010.
