Creating charts in VB.net

Hi

I'm trying to create a line graph in vb.net using the MSGraph reference and data from a access database.

New data is to be added daily and the graph updated with new plots to reflect the changes in data. Would this be the best way to go about this:

1. Open the database connection
2. Read the values from the table
3. Input them into an 2D array
4. Read through the array to plot the points?

Thanks
