Transform Points

Follow these steps to build Affine transformation:

To select series of points in list, double click on it.
The dialog 'Information on points series' opens.
Click the <Transform...> button.
The dialog Transform selected points to new series... starts.
On a page Formula we choose relations Y( u, v )=v*16/(u*u + v*v) and X( u, v )=u*16/(u*u + v*v).
On a page Series we select color, marker, and radius of points.
Input series title.
Use the <Apply> button as Preview.
New series of points appears.

Follow these steps to subtract regression line:

To select series of points in list, double click on it.
The dialog 'Information on points series' opens.
Click the <Function...> button and build the regression line Y( x ) = Yappr(x).
Click the <Transform...> button.
The dialog Transform selected points to new series... starts.
On a page Formula we choose relations Y( u, v ) = v - a + b and X( u, v ) = u.
Select parameter a = Yappr.
Select parameter b = Medium Y.
On a page Parameters we vary parameter c = 0.
On a page Series we select color, marker, and radius of points.
Input series title.
Use the <Apply> button as Preview.
New series of points appears.

Examples:

Y( u, v ) = 4/v; X( u, v ) = 4/u;
Y( u, v ) = v*16/(u*u + v*v); X( u, v ) = u*16/(u*u + v*v);
Y( u, v ) = v/ a + b; X( u, v ) = u; a = approximation y( x ), b = Ymedium;
Y( u, v ) = (v-a + b)/c; X( u, v ) = u; a, b, c - formulas.
