Bug with animation when updating series of an area chart

[johannagere]

In our application, we have charts of different types (line and area charts) and we update the series-data of the charts every few seconds. When the charts are drawn initially, we want the lines/areas to be animated. However, when the series are updated we don't want the lines/areas to be completely re-animated again. Instead, only the new values should be drawn. To achieve this behaviour, we have set the animations property in the chart options to
animations: { enabled: true, easing: 'linear', dynamicAnimation: { speed: 1000 } },
and we update the series of our charts like this every few seconds
chart.options.series = updatedSeries;
For line-charts this setup leads to the behaviour we want, which means only the new values are drawn but the lines are not completely re-animated. However, for area-charts, this setup causes all the areas to be re-animated every time the series are updated. To avoid this, we tried to set the redrawPaths and animate properties in the updateOptions -method of the area-chart to false but this didn't fix this issue either. Does anyone know how we can prevent the areas to be redrawn on a series-update without having to disable animations completely?
