SubLayer_Correl
Displays a square matrix that has all entries -1 <= x <= 1, as a square subdivided into squares of color; see ScaleToColor.

SubLayer_CorrelSquare

Functions

[hide private]

make_frame(w, h, appearance, controls_showing)
Returns (left, top, right, bottom) pixel coords, telling where to draw the graph given that the whole space has dimensions (w,h).

source code

source code

make_y_transform(u0, u1, y0, y1)
Returns (y2u, u2y), where u=y2u(y) and y=u2y(u), mapping u in [u0..u1] to y in [y0..y1].

source code

gen_grid(u0, u1, z0, z1, appearance)
Yields successive gridline u-coordinates along one dimension.

source code

read_data(f)
Returns (series, names) read from file-like object f.

source code

pick_xy(series, names, x_name, y_name)
Given (series, names) from read_data, and preferred x- and y- series names, returns the most appropriate 2 series.

Function Details

[hide private]

gen_grid(u0, u1, z0, z1, appearance)

source code

Yields successive gridline u-coordinates along one dimension.

Parameters:

u0 - lowest value showing
u1 - highest value showing
z0 - lowest x- or y- coord
z1 - highest x- or y- coord
appearance - qubx.toolspace.TS_Appearance

read_data(f)

source code

Returns (series, names) read from file-like object f. The file should be tab- or comma-separated text. The first line can have column labels. Returns series, a list of numpy.array(dtype='float32'), one per column, and names, a list of str identifiers. Blank names are replaced with Y%i. If there's only one column, an ordinal series 'X' is prepended.

pick_xy(series, names, x_name, y_name)

source code

Given (series, names) from read_data, and preferred x- and y- series names, returns the most appropriate 2 series.

Returns:: (x_series, y_series, index of x_series, index of y_series)

COLOR_FITSPACE_BACKBUTTON

Value:

('fit.backbutton', (0.2, 0.3, 0.2, 1))

TheFitCopyDialog

Value:

<CopyDialog object at 0x7fd1234b9410 (GtkDialog at 0x2ff20e0)>

FIT_SPACE_HELP

Value:

'''You can enter either a function, such as
        amp * exp(-x / tau)
or a system of differential equations, such as
        y1\' = a*y2; y2\' = b*y1
The first integrated variable (e.g. y1) will be used for fitting.

You can use the minimum/maximum values of any variable, e.g.
        hi("y") - lo("y")
