Real-time Charts

Is it possible to create a LineChart that is continuously updated as data is loaded every 5 seconds, with the chart smoothly scrolling to the left as new data points are plotted?

Don't we have a sample for real time graphs in iOS which is similar to that used in Android Charts (RealtimeLineChartActivity)

but how to change the yaxis max value, and in project when i add point to line , it compress the line in x direction, so the point in view is become more and more, can it move to left dynamicly?

Try removing the entry at the beginning of the dataset each time you add a new entry:

data.removeEntryByXIndex(0, dataSetIndex: 0)

This creates kind of a push and pop. Not sure this will meet your needs as this kinda makes the graph choppy.

Also self.lineChartView.setVisibleXRange(minXRange: CGFloat(1), maxXRange: CGFloat(50)) with
self.lineChartView.moveViewToX(CGFloat(i)) worked for me.
