If you look for "Chart Knitting", you'll find some help.
I'm no expert, but I've knit a couple charts. They aren't as hard as you think they will be.
You usually start knitting on the bottom row, reading right to left. Then, you move up to the next row, and read the symbols left to right. Then, you keep going backwards and forwards through the rows. Your knitting will start to look like the image on the chart.
