What are the requirements for the past performance line graph?

The line graph must show the performance of a £10,000 investment, or an equivalent amount in another currency that is divisible by 1,000. It must include at least one data point per month, with the last day of each month included in the time series. The x-axis must be expressed in calendar years (or parts thereof), and the y-axis must be linear, showing values as whole-number amounts.
