high memory consumption of Series
posted

Hey Infragisitics Team,

my example iPad App has high memory consumption by using 36,000 datapoints. Each series of ChartView allocate more than 100 MB of RAM. Is that normal? I have two Series with IGCategoryDateTimeXAxis.

The example App contains one view with two Charts (one MainChart and one ZoombarChart as RangeSelector). I create a model object for this data points with two properties. One date property and one value property. For data binding The IGCategoryDateSeriesDataHelper produce for each series a sequence of IGDatePoint. I build the chart view like the guideline from Developer Guideline.

Is there a best practice solution to reduce the memory consumption? Finally, both series use the same data.

Kind regards,
