Spline Chart Maker

This spline (curved line) chart maker (with dates functionality) allows you to create simple and complex spline charts that provide a visual representation of your data.

Simple Instructions

The easiest way to create the chart is just to input your x values into the X Values box below and the corresponding y values into the Y Values box. Then scroll to the bottom of the page, and hit 'Create Chart'.

If your x values are dates, then you need to select the X-Axis is Datetime option, and specify your input and output format (e.g., MM-DD-YY).

Options

You can choose a number of options for your spline chart, including its title and axes labels, and whether you are plotting dates. You'll be offered further editing options after the tool has generated the chart.
