Expected CSV format: header row "year,SeriesA,SeriesB,..." (with "year" as the year column), values separated by commas - the same wide format as in the periodisation analyser and the data import assistant. Loading several files or loading repeatedly adds further series without replacing those already loaded.

➕ Calculate new series from formula
Refer to series by their symbol (Z1, Z2, …); operators + − * /, power ^ and brackets. Coefficients as numbers (e.g. 0.5) or as placeholders a1, a2, … – input fields appear below for placeholders. Also available: ln(), exp(), sqrt(), abs(). The calculation uses the original values, year by year; years in which a series used is missing or a division by 0 would occur remain empty.
3. Individual charts
The series marked under "Compare" in section 2, each with the transformation selected there.
No series marked for the comparison chart yet.
4. Comparison chart
Shows all series marked under "Compare" in section 2 together (each with its own transformation). With different scales/units, a common y-axis is only of limited informative value.
No series marked for the comparison chart yet.
Comparison of HP trends
The same marked series, each showing only the smoothed HP trend (instead of the raw values) - makes it easier to compare long-term developments without short-term fluctuations.
5. Export
The export always contains the original values of the series marked under "Export" (regardless of the transformation selected for display) in wide format, covering all years of the selected series; missing values are kept as empty fields.
