The chart has a title, and is positioned to the right of column 2 and sized 800 pixels wide The X-axis is labelled "Degrees", in bold 12 point type and runs from 0 to 361 with labels every 30, and minor tick marks every 10. Degrees are shown padded to 3 digits. The Y-axis is labelled "Sine" and to allow some room above and below its scale runs from -1.25 to 1.25, and is marked off in units of 0.25 shown to two decimal places.
