y axis range not automatically recalculated when adding entry to data set

[SimonNick]

Hi guys,

When I add a data entry to a entry data set of a line plot the y axis range of the chart data is not recalculated.

let dataSet = lineChartView.data!.getDataSetByIndex(0)
let dataEntry = ChartDataEntry(x: 12.0, y: 30.0) // where 30.0 > maximum of other y values
dataSet?.addEntryOrdered(dataEntry)
lineChartView.data?.calcMinMax() // if i do not call this the y axis range is wrong
lineChartView.notifyDataSetChanged()

I have to call calcMinMax() to recalculate the range of the y axis. The x axis seems to be fine.

Is it intended or a bug?

Best,
Nick

it's intended. as you have add new data, you can call lineChartView.data?.notifyDataChanged actually. it will call calcMinMax() for you.
