sas.qtgui.Plotting.Fittings module
This module is used to fit a set of x,y data to a model passed to it. It is used to calculate the slope and intercepts for the linearized fits. Two things should be noted:
First, this fitting module uses the NLLSQ module of SciPy rather than a linear fit. This along with a few other modules could probably be removed if we move to a linear regression approach.
Second, this infrastructure does not allow for resolution smearing of the the models. Hence the results are not that accurate even for pinhole collimation of SANS but may be good for SAXS. It is completely wrong for slit smeared data.

sas.qtgui.Plotting.LineModel module
Provide Line function (y= Ax + B). Until July 10, 2016 this function provided (y= A + Bx). This however was contrary to all the other code using it which assumed (y= mx+b) or in this nomenclature (y=Ax + B). This lead to some contortions in the code and worse incorrect calculations until now for at least some of the functions. This seemed the easiest to fix particularly since this function should disappear in a future iteration (see notes in fitDialog)

sas.qtgui.Plotting.Plottables module
Prototype plottable object support.
The main point of this prototype is to provide a clean separation between the style (plotter details: color, grids, widgets, etc.) and substance (application details: which information to plot). Programmers should not be dictating line colours and plotting symbols.
Unlike the problem of style in CSS or Word, where most paragraphs look the same, each line on a graph has to be distinguishable from its neighbours. Our solution is to provide parametric styles, in which a number of different classes of object (e.g., reflectometry data, reflectometry theory) representing multiple graph primitives cycle through a colour palette provided by the underlying plotter.
A full treatment would provide perceptual dimensions of prominence and distinctiveness rather than a simple colour number.

sas.qtgui.Plotting.Plottables.
Graph
(**kw)[source] Bases:
object
Generic plottables graph structure.
Plot styles are based on color/symbol lists. The user gets to select the list of colors/symbols/sizes to choose from, not the application developer. The programmer only gets to add/remove lines from the plot and move to the next symbol/color.
Another dimension is prominence, which refers to line sizes/point sizes.
Axis transformations allow the user to select the coordinate view which provides clarity to the data. There is no way we can provide every possible transformation for every application generically, so the plottable objects themselves will need to provide the transformations. Here are some examples from reflectometry:
independent: x -> f(x) monitor scaling: y -> M*y log: y -> log(y if y > min else min) cos: y -> cos(y*pi/180) dependent: x -> f(x,y) Q4: y -> y*x^4 fresnel: y -> y*fresnel(x) coordinated: x,y = f(x,y) Q: x -> 2*pi/L (cos(x*pi/180) - cos(y*pi/180)) y -> 2*pi/L (sin(x*pi/180) + sin(y*pi/180)) reducing: x,y = f(x1,x2,y1,y2) spin asymmetry: x -> x1, y -> (y1 - y2)/(y1 + y2) vector net: x -> x1, y -> y1*cos(y2*pi/180)
Multiple transformations are possible, such as Q4 spin asymmetry
Axes have further complications in that the units of what are being plotted should correspond to the units on the axes. Plotting multiple types on the same graph should be handled gracefully, e.g., by creating a separate tab for each available axis type, breaking into subplots, showing multiple axes on the same plot, or generating inset plots. Ultimately the decision should be left to the user.
Graph properties such as grids/crosshairs should be under user control, as should the sizes of items such as axis fonts, etc. No direct access will be provided to the application.
Axis limits are mostly under user control. If the user has zoomed or panned then those limits are preserved even if new data is plotted. The exception is when, e.g., scanning through a set of related lines in which the user may want to fix the limits so that user can compare the values directly. Another exception is when creating multiple graphs sharing the same limits, though this case may be important enough that it is handled by the graph widget itself. Axis limits will of course have to understand the effects of axis transformations.
High level plottable objects may be composed of low level primitives. Operations such as legend/hide/show copy/paste, etc. need to operate on these primitives as a group. E.g., allowing the user to have a working canvas where they can drag lines they want to save and annotate them.
Graphs need to be printable. A page layout program for entire plots would be nice.

Transform
[source] Bases:
object
Define a transform plugin to the plottable architecture.
Transforms operate on axes. The plottable defines the set of transforms available for it, and the axes on which they operate. These transforms can operate on the x axis only, the y axis only or on the x and y axes together.
This infrastructure is not able to support transformations such as log and polar plots as these require full control over the drawing of axes and grids.
A transform has a number of attributes.
- name
- user visible name for the transform. This will appear in the context menu for the axis and the transform menu for the graph.
- type
- operational axis. This determines whether the transform should appear on x,y or z axis context menus, or if it should appear in the context menu for the graph.
- inventory
- (not implemented)
a dictionary of user settable parameter names and
their associated types. These should appear as keyword
arguments to the transform call. For example, Fresnel
reflectivity requires the substrate density:
{ 'rho': type.Value(10e-6/units.angstrom**2) }
Supply reasonable defaults in the callback so that limited plotting clients work even though they cannot set the inventory.
