- | ====== Guess Peaks (Pro only) ====== | + | * fit has not converged, suspicious curve |
- | MagicPlot can approximately locate peaks in spectrum. To locate peaks click on '' | + | |

- | ====== Using Spline for Baseline Subtraction ====== | + | |
- | You can use cubic spline to fit and subtract baseline on Fit Plot. To create spline curve click on '' | + | |

- | ===== Fitting with Spline ===== | + | |
- | + | ||
- | Spline anchor point (//x//, //y//) coordinates are treated as fit parameters | + | |
- | + | ||
- | We recommend you to set appropriate fit intervals which contains only baseline without peaks. In such case '' | + | |

- | ====== Integrals and Statistics on Intervals ====== | + | |
- | Setting intervals in '' | + | |
- | + | ||
- | MagicPlot is capable to integrate data on selected intervals and to calculate peak moments (x mean, variance, skewness, kurtosis). Spectrum line is treated as probability distribution curve: //x// values are treated as ' | + | |
- | + | ||
- | Statistical data and integrals are automatically updated if //x// or //y// data is changed or intervals are changed. | + | |
- | + | ||

- | ===== Relative Integrals Calculation ===== | + | |
- | MagicPlot is capable of calculation relative integrals to compare the relative intensity of spectrum lines. To compute relative integrals set '' | + | |

- | ===== Displaying Column Formulas in Table ===== | + | |
- | MagicPlot indicates columns for which formulas or other evaluators (FFT, integral, etc.) are set with blue header color. You can see the formula in column header tool tip. | + | |
- | + | ||
- | {{: | + | |
- | + | ||
- | On the screenshot above: | + | |
- | * Column A has no formula | + | |
- | * Column B has formula, auto recalculation is off | + | |
- | * Column C has formula, auto recalculation is on, so this column is not editable | + | |
- | + | ||
- | ===== Fit Column Widths ===== | + | |
- | To fit the width of one column double click on right separator line in table header. To fit selected columns widths double click one of column separators in table header. | + | |
