Simple spline Part of PowerCharts XT
A spline chart is a specialized form of the line chart that can be used for plotting data that requires the usage of curve-fitting. Like the line chart, data values are plotted as data points. However, instead of using straight line segments to connect the data points, this chart draws a fitted curve to connect the data points. This chart can be used for applications such as rendering the impulse-response of a system or the development lifecycle for a product.
- Use the spline chart to show gradual changes in data, instead of spikes.
- Keep it simple, do away from anything that is unnecessary like grid lines.
- Highlight the critical elements.
- Choose a baseline that suits your data; choosing a zero baseline may not represent the change in data effectively.
