+ | If your initial data to be integrated contains a baseline (usually constant or linear), you may want to subtract it from data **before** integrating. (A constant baseline will result in linearly growing integral.) | ||
+ | |||
+ | In such case the algorithm may be the following: | ||
+ | - Create Fit Plot with your initial table data | ||
+ | - Add a Fit Curve which simulates the baseline. You may specify a custom equation | ||
+ | - Specify Fit Interval so that it contains only noise points | ||
+ | - Fit the data by clicking '' | ||
+ | - Subtract the baseline fitting curve from data by checking '' | ||
+ | - Use menu '' | ||
