Graphics

These pages mainly involve plotting data on graphs. For example, chart can plot the results of any formula you type in whilst Spirograph performs a series of calculations in order to draw a Spirograph.

• Chart A spreadsheet which can graph a given formula
• Spirograph This will plot a Spirograph when given the necessary measurements.
• Trend lines A small code sample that will automatically apply the best trend line to an Excel chart. No more worrying about Logarithmic and Polynomial - this code does all of those hard decisions for you.
