### Tools

Click the button
or select menu item <Analysis><Transformation> to create new series.
Select tool:

**Copy** to exchange (X, Y), to exchange (Y, Z), transpose (X, Y) to (row number, X) or to (row number, Y),
flip X or flip Y values, simulate data (Y values) with random error;
**Linear** to translate, scale, rotate data;
**Subtract** to subtract or divide data on const, or baseline, or function you input;
**Formula** to transform points;
**Normalize** to normalize data between Y limits you define;
**Prune** to skip or to combine rows (take the arithmetic mean or the harmonic mean or the geometric mean) and or exclude data out of limits X;
**Spikes **to exclude random spikes or to exclude close points;
**Neighbours **to exclude replicating points, or to exclude points near existing plot, or to exclude points near function.
**Smooth** to apply adjacent averaging;
**Interpolate** to generate a new curve with a constant spacing on the X axis;
**Differentiate** to calculate derivatives;
**Integrate** to calculate integrals.
**Convex Hull** to construct a discrete Convex Hull as a new series;
**Filter** to eliminate noise with FFT filters;

In all dialogs you can modify properties of new series
(formulas, parameters, color, radius and so on).

### Formula

It is possible to transform selected points ( u, v ) and create new series of points
( x, y ) in the form

**y( u, v ) = f2(u, v), x( u, v ) = f1(u, v)**.
You can use parameters **a, b, c, d** in formula: Const; Medium values of x and y;
Any Function or the Formula you created.

*Notes:*

- Only variables
**u, v** and parameters **a, b, c, d** are possible in formula expression.
- Default value of parameters is 0.
