c# - Line Chart with date and time on X axis -

-

i working line chart using zedgraph , c# in visual studio 2010. values ​​are coming serial port. date , time entering x axis, each interval number of seconds change , seems weak , lacking harmony. how solve this?

this video shows problem.

maybe try using:

        mypane.xaxis.type = axistype.date;         mypane.xaxis.scale.format = "hh:mm";         mypane.xaxis.scale.majorstepauto = false;         mypane.xaxis.scale.minorstepauto = false;         mypane.xaxis.scale.majorunit = dateunit.minute;         mypane.xaxis.scale.minorunit = dateunit.minute;         mypane.xaxis.scale.minorstep = minor;         mypane.xaxis.scale.majorstep = major;         mypane.xaxis.scale.min = min;         mypane.xaxis.scale.max = max;         mypane.xaxis.scale.maxauto = false;         mypane.xaxis.scale.minauto = false;         mypane.yaxis.scale.min = min_rr;         mypane.yaxis.scale.max = max_rr;

for minorstep , majorstep must use value 3, 5, 30 etc. max , min use eg:

xdate min = new xdate(1999, 1, 1, 0, 0, 0, 0); xdate max = new xdate(1999, 1, 1, 0, 30, 0, 0);

in changing axis type in zedgraph have example dateasordinal x axis.

i hope helps. cheers.
