public String DateTimeFormat {get; set;}
Remarks
Chart AxisLabels have a DateTimeFormat property. DateTimeFormat is a standard DateTime formatting string specifier. Chart Axis uses it to draw the axis labels.
Specifier Displays
c Displays the date using the format given by the ShortDateFormat global variable, followed by the time using the format given by the LongTimeFormat global variable. The time is not displayed if the fractional part of the DateTime value is zero.
d Displays the day as a number without a leading zero (1-31).
dd Displays the day as a number with a leading zero (01-31).
ddd Displays the day as an abbreviation (Sun-Sat) using the strings given by the ShortDayNames global variable.
dddd Displays the day as a full name (Sunday-Saturday) using the strings given by the LongDayNames global variable.
ddddd Displays the date using the format given by the ShortDateFormat global variable.
dddddd Displays the date using the format given by the LongDateFormat global variable.
M Displays the month as a number without a leading zero (1-12). If the m specifier immediately follows an h or hh specifier, the minute rather than the month is displayed.
MM Displays the month as a number with a leading zero (01-12). If the mm specifier immediately follows an h or hh specifier, the minute rather than the month is displayed.
MMM Displays the month as an abbreviation (Jan-Dec) using the strings given by the ShortMonthNames global variable.
mmmm Displays the month as a full name (January-December) using the strings given by the LongMonthNames global variable.
yy Displays the year as a two-digit number (00-99).
yyyy Displays the year as a four-digit number (0000-9999).
h Displays the hour without a leading zero (0-23).
hh Displays the hour with a leading zero (00-23).
m Displays the minute without a leading zero (0-59).
mm Displays the minute with a leading zero (00-59).
s Displays the second without a leading zero (0-59).
ss Displays the second with a leading zero (00-59).
fff Displays the millisecond (0.000 - 0.999)
t Displays the time using the format given by the ShortTimeFormat global variable.
tt Displays the time using the format given by the LongTimeFormat global variable.
am/pm Uses the 12-hour clock for the preceding h or hh specifier, and displays 'am' for any hour before noon, and 'pm' for any hour after noon. The am/pm specifier can use lower, upper, or mixed case, and the result is displayed accordingly.
a/p Uses the 12-hour clock for the preceding h or hh specifier, and displays 'a' for any hour before noon, and 'p' for any hour after noon. The a/p specifier can use lower, upper, or mixed case, and the result is displayed accordingly.
ampm Uses the 12-hour clock for the preceding h or hh specifier, and displays the contents of the TimeAMString global variable for any hour before noon, and the contents of the TimePMString global variable for any hour after noon.
/ Displays the date separator character given by the DateSeparator global variable.
: Displays the time separator character given by the TimeSeparator global variable.
'xx'/"xx" Characters enclosed in single or double quotes are displayed as-is, and do not affect formatting.
Format specifiers may be written in upper case as well as in lower case letters--both produce the same result.
If the string given by the Format parameter is empty, the date and time value is formatted as if a 'c' format specifier had been given.
Example
[C#]
((Line)tChart3[0]).XValues.DateTime=true;Using Axis DateTime
tChart3.Axes.Bottom.Labels.DateTimeFormat="dd/MM/yyyy";
What can we do to ignore pre-defined dates in the Regional Options?
For example to ignore the Regional Options and set the date followed by AM or PM we can use :
For it to work correctly we need to format the date as above "MM/DD/YY", and NOT "DD/MM/YY".
using System.Globalization;
using System.Threading;
private void Form1_Load(object sender, System.EventArgs e)
{
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
label1.Text=DateTimeFormatInfo.CurrentInfo.AMDesignator;
line1.XValues.DateTime = true;
tChart1.Axes.Bottom.Labels.Angle = 90;
for(int i = 1; i <= 31; ++i)
{
string tempDate = "12/"+i.ToString() + "/2002 AM";
line1.Add(DateTime.Parse(tempDate).ToOADate(),i,Color.Red);
}
tChart1.Axes.Bottom.Labels.DateTimeFormat = "MM/dd hh:mm tt";
}
How can we use the format defined in the Regional Options and force the change of AM and PM without altering any other parameter?
You can use the following:
This takes everything defined in the Regional Options and only changes AM / PM
CultureInfo c=new CultureInfo(CultureInfo.CurrentCulture.LCID,true);
c.DateTimeFormat.AMDesignator="AM";
c.DateTimeFormat.AMDesignator="PM";
Thread.CurrentThread.CurrentCulture=c;
Here we are able to add dates with the "DD/MM/YY" format.
We suggest you work with the defined Regional Options, and NOT to use Dates with Strings, but to use numbers:
DON'T USE --> string tempDate = i.ToString() + "/12/2002 AM";
USE --> DateTime d=new DateTime(2002,12,i,10,00,00,00);
