Beginning charting

Hello,

I have just began to chart using Excel.

I have some data calculated by a VBA program and would like to chart it, I was able to do a very simple one but I would like to customize it more.

If you could tell me how to set the maximum x and y value, I would be glad

I was not able to find a simple site which explains how to do simple things (chart color, line type, legend, title ...), if you have any, I will be pleased to check them.

Here is my code

'Initialisation
With Graph1
    Do Until .SeriesCollection.count = 0
        .SeriesCollection(1).Delete
    Loop
End With

With Graph1
    .name = "graph_name"
    .Type = xlLine
    .SeriesCollection.NewSeries.Values = Array(Feval) 'Feval is an array data
End With

Thank you in advance.
