just using `aChart.configuration = ....` with new ...

just using aChart.configuration = .... with new Configuration object containing new data should work
so I would try to:

1. create a helper function to get current configuration:

fun getChartConfig() = Configuration(
        ChartType.PIE,
        listOf(
            DataSets(
                data = pieSizes
            )
        )
    )

2. create a chart with the help of this function:

val aChart = Chart(getChartConfig())

3. subscribe to the observable list:

pieSizes.onUpdate += {
   aChart.configuration = getChartConfig()
}

The pieSizes.onUpdate is neat and works as expected. Got the problem with the Configuration, though, If I add it as you suggest I get an exception at each update. It seems the labels argument is mandatory, even though it is specified as "val labels: List<String>?" in the documentation. If I add an "listOf(") the chart update works as I want.

But, I do not want the labels beside the chart. Take too much space, and I have my own label implementation through a tabulator table. 🤔

Now I got it to work the way I want. To summarise. I took your example, added a listOf() labels, and finally applied the options = ChartOptions(responsive = false, legend = LegendOptions(display = false)) to get rid of the labels beside the charts. Thanks a lot!🙂
