X-axis to start from 0

I know this question has been asked before quite a few times, but no one seems to have come up with a solution (Not that I could find at least).

So, I have a chart for my application and I've added values

chart1.Series["Life"].Points.AddY(1);
chart1.Series["Life"].Points.AddY(30);
chart1.Series["Life"].Points.AddY(20);
chart1.Series["Life"].Points.AddY(50);

for which I get a chart like


Now this is very displeasing to the eye first of all because the X needs to start from the origin. So, question 1 - Why is it starting from 1? Question 2 - How do I solve this? This is the first time I am making a chart in c# so this might sound like a trivial dilemma.

Also, like I mentioned, I did my research and I found that I should do something like

chart1.ChartAreas[0].AxisX.Interval = 0;
chart1.ChartAreas[0].AxisX.IsStartedFromZero = true;
chart1.ChartAreas[0].AxisX.Minimum = 0;    //made this -1
chart1.ChartAreas[0].AxisX.Crossing = 0;   //and this too to -1

This didn't work so I decided to play a little with the minimum and crossing by giving them -1. Didn't work. The graph not only moved, but it still starts from 1. HOW?

You could use the Points.AddXY method to specify the X coordinate too. To make sure that the line starts from the origin prepend data points with (0, 0):

var series = chart1.Series["Life"];
series.Points.AddXY(0, 0);
series.Points.AddXY(1, 1);
series.Points.AddXY(2, 30);
series.Points.AddXY(3, 20);
series.Points.AddXY(4, 50);
chart1.ChartAreas[0].AxisX.Minimum = 0;

So you want your chart X-axis to start at 1? why not use:

chart1.ChartAreas[0].AxisX.Minimum = 1;

?

or you want your points to start at 0? why not use :

chart1.ChartAreas["Life"].AxisX.Minimum = 0;
chart1.Series["Life"].Points.AddXY(0,1);

?
