c# - How to draw graph using chart in .net windows forms based on time(seconds) -

-

my requirement draw graph using chart control in .net(windows form or wpf) in c# or vb.net update data serial port.the graph should show received data , plot load value(y axis) against time(x axis).the interval should in seconds , should keep on moving left in ecg or oscilloscope.

i made graph not scaling second intervals , not moving , redrawing left.

i don't think there built in chart function. guess need split up.

＞make array, hold data points.

＞then use timer, , ontimerevent method, put next data point in array, , move along, deleting last one.

＞and refresh--delete , add--all chart data points array values

timer: http://msdn.microsoft.com/en-us/library/393k7sb1(v=vs.110).aspx
