Integration

Open Table or Figure or Plot with initial data and use Processing -> Integrate menu item.

Integrate table columns dialog Integrate curve dialog

Baseline Correction

If your data to be integrated contains a baseline (usually constant or linear), you might to subtract it from data before integrating. The constant baseline will result in linearly growing integral.

In such case the algorithm may be the following:

Create Fit Plot with your data

Add a Fit Curve which simulates the baseline. Usually it will be Line Fit Curve. You may specify you own equation (Pro only)

Specify Fit Interval so that it does contain only noise points

Fit the data

Subtract the baseline fitting curve from data by checking 'Baseline' check box in curves table

Use menu Analysis → Integrate to integrate the data without baseline

Formula

To perform integration you should specify two columns: x and y. Missing values are ignored.

MagicPlot uses trapezoidal rule to compute the integral:
