Not sure how you want to make chart. If you have Ami, you can upload the data to it. If you want it in excel, 1 min for 3 years data will make huge chart.
For ami, u can import via file-import data-pick file. Just follow the steps and make sure formats are same as your data.
For excel.. simple.. keep only 4 colums.. open, high, low, close. Go to insert an select chart (u can see the chart type). Google a lil bit.. will be easy.
