Maths Curve Data Check

Calculate smoothed data values from raw input data.

The calculator is intended for checking and smoothing digitised plot data. Use the Result Plot option to display the data value, slope and curvature. The value, slope and curvature curves should be smooth. Sudden changes in slope and or curvature indicate possible faulty values.

Options include data order (ascending or descending data), plot axies (Z versus X or X versus Z), smoothing type, and whether to smooth the maximum and minimum values. Smoothing uses a simple weighted mean value.

CALCULATOR : Data Check Plot (Vector Data) [FREE]   ±

Calculate smoothed value, slope, and curvature from vector data points.

Options include reverse data order (ascending or descending), and reverse plot type (Z versus X or X versus Z). Enter data as comma or tab separated pairs (X,Z), with each pair on a new line (or copy and past cells from a spreadsheet). Use the Result Plot option to plot the data points.
