#18 (c#)There is any way to draw AbscissaData in the same order which in reading?

[Munteanu Laura Loredana]

Hello all,

Sorry if I did submit the ticket in the correct location or to the corect person but I'm a new member and I'm quite new using c#.
I'm wondering if there is any possibility to draw the AbscissaData in the same order which in reading in c#?
For IDrawable I'm using Grid and data which is coming for AbscissaData is a DateTime[] struct.
Ex: DateTime[] ={ 2018-09-25 11:25:35, 2018-09-26 11:26:35, 2018-09-24 11:25:35, 2018-09-23 11:27:35}

For the moment, the x-coordinates are displayed chronologically , meaning 2018-09-23 11:27:35, 2018-09-24 11:25:35, 2018-09-25 11:25:35, 2018-09-26 11:26:35 but I want it to be dispalyed in the same order which is reading.
Bellow you can find my method where I'm plotting the data.

Could please help me? I'm missing some method that I can use? Any hint would be very helpful
Many thanks,
Loreadana
