Hello everyone !
Firstly thank you for your help, and sorry if my English isn't well !
I'm a beginner, hence the fact I need your help :
I've got a program where I have a datagridview which displays an excel file with many columns. But I want to display a graphic ( in a second form ) which will use just 3 columns out of dozen ^^.
In the file, the 3 columns which I want to use are :
> A column with the month when I have to contact the client(s) ( perhaps my axe X )
> The name of client(s)
> The name of the product that the client(s) have
And if it's possible, use the number of clients in a month for my axe Y.
Thank you for your help !
