Simple spline-area Part of PowerCharts XT
A spline area chart is a specialized form of the area chart that can be used for plotting data that requires the usage of curve-fitting. Like the area 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.The area between the curve and the x-axis is filled with color. 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. -Start the y-Axis at 0 to accurately reflect the proportionate difference in data. -Use appropriate colors to show the trend.
