## GVIEW2D: Calculation Examples

### From BAWiki

## Contents

This page shows some data visualizations generated by the calculation functions offered by the program GVIEW2D.

## Example: Moving average

Moving average by a time window sized to period of the M2 tide.

## Example: Derivative with respect to time

The lower chart shows the derivate of the water level with respect to time.

## Example: Scatter plot

The chart shows the values of two water level time series against each other. The legend of the scatter plot curve contains the mean values of the basic time series calculated in the user specified period of analysis. Also the linear regression belonging to the scatter plot data is on display. The calculated regression coefficients are added to the legend text of the regression line.
