delphi - Plotting a TChart with time as the X-axis -

-

i have series of 3,600 values, 1 every second hour. want chart them single series, using tchart in delphi 7.

the values should plotted on y-axis. should pass addxy() x-axis value? count of points?

i want label x-axis mm:ss, how do that? need beyond this? ... 

   chart1.series[0].xvalues.datetime := true;    chart1.bottomaxis.datetimeformat := 'nn:ss';

i have been stuck while one. can post sample code? thanks

if not wrong, want

series1.addxy(<pass data value>, <pass value>, '', clred); series1.addxy(now,                     1, '', clred);  series1.addxy(now + ( 1 /(24*60*60)),  2, '', clred); //after 1 seconds  series1.addxy(now + ( 2 /(24*60*60)),  3, '', clred);  //after 2 seconds
