Hi,

I have a stacked column series and I want to animate changes to the values. I have succesfully done this for IGColumnSeries by setting animateSeriesWhenAxisRangeChanges and transitionDuration and setting the data property of the datasource whenever there are changes. However, I cant do the same with a stacked series as the data property of IGStackedSeriesDataSourceHelper is readonly. Here is my code

    IGStackedSeriesBase *stackedSeries = (IGStackedSeriesBase *)[self.barchart findSeriesByKey:kVisitTypeSereisKey];
    IGStackedSeriesDataSourceHelper *datasource = (IGStackedSeriesDataSourceHelper *)stackedSeries.dataSource;
    datasource = [[IGStackedSeriesDataSourceHelper alloc] initWithData:data fields:stackedColumnFields labelPath:seriesLabelPath];
    if (!stackedSeries) {
        stackedSeries = [self.barchart addStackedSeriesForType:[IGStackedColumnSeries class] usingKey:kVisitTypeSereisKey withDataSource:datasource firstAxisKey:XAIXS_KEY secondAxisKey:YAXIS_KEY];
        stackedSeries.transitionDuration = CHART_ANIMATION_DURATION;
    }
    stackedSeries.dataSource = datasource;

Thanks,

Aniruddh
