In Joining the Parameters of Fit Curves - new topic from Nonlinear Curve Fitting: Fit Plot

Joining the Parameters of Fit Curves

In some cases you may want to fit the data with two Gauss or Lorentz peaks with the same width but different positions and amplitudes, for example. You can do this in two ways: by specifying custom Fit Curve with your equation or by joining the 'width' parameters of two peaks.

To join parameters of two or more Fit Curves select one of desired Fit Curves, then select desired parameter in parameters table and press Join button in the bottom of the panel (or double click on parameter).

Joining Fit Parameters

You can specify the selected parameters as equal or proportional by entering multiplier and constant for each parameter.

Joined parameters are shown with blue color (instead of black) in curve parameters table.

In Importing Table from Text File (ASCII) new screenshot...

In Creating a Copy of Table, Fit Plot, Folder or Figure new topic

Creating a Copy of Table, Fit Plot, Folder or Figure

You can create a full copy of selected project components (Tables, Fit Plots, Folders, Figures) by selecting Create a Copy item on context menu.

Create a Copy Menu Item

Creating a Copy of Fit Plot or Figure

If the only Fit Plots and Figures are selected for creating a copy, the created Fit Plots and Figures will use data from the same tables as initial ones. If you select also the Tables which contain plotted data then the created Fit Plots and Figures will use data from created copies of Tables.

In Nonlinear Curve Fitting: Fit Plot:

about changing curves order by dragging

about adjusting parameters with mouse wheel

fit has not converged, suspicious curve

In Keyboard Shortcuts about infinity, columns rearranging on linux with Meta/Win key, Print/preview shortcut

In Adding and Arranging Axes Boxes on a Figure new screenshot

MagicPlot 1.4, Major update, Feb 2011

Added: Joint parameters can be proportional, not only equal

Added: Reading and renaming table column names when importing tables from text files

Added: Import tables from clipboard with import wizard

Added: Setting the scale of selected axes in inspector toolbar

Added: Creating a copy of Tables, Fit Plots and Figures

Added: Curve selection, editing cure style in inspector panel without dialog opening

Added: Cut, Copy and Paste curves between Fit Plots and Figures

Added: Tab/Shift+Tab and arrow keys select next/previous curve on plot or figure

Added: Changing Fit Curves order by dragging in curves table

Added: Adjusting parameters with mouse wheel (with Ctrl pressed)

Added: Help about inserting Greek letters and math symbols in shortcuts window

Added: 'Colorize Selected' item in color button menu when multiple curves are selected

Added: Parameters covariance matrix in Fit Report

Improved: Correct processing of missing values and repeated column delimiter in imported text file with table

Improved: Highlighting of suspicious curve (peak) if fit has not converged

Improved: Text redrawing on Figures and Fit Plots was optimized: much faster redrawing of big texts

Improved: New table is created in selected dataset in project tree if any

Improved: Adding Figure components in Figure properties dialog: project tree view improved, double click support

Improved: Using row number as X when adding data to Figure

Improved: Setting y error column just in import wizard, adding multiple data without closing dialog

Improved: Image zoom “smoothed”

Improved: Scale (linear/log10) type is now saved in Figure templates

Improved: Adding data to Figure from multiple Tables (in Figure properties dialog): Column selection dialog is showed once for all Tables

Improved: Continuous interval selection of legend labels (and curves) with Shift

Improved: Fit stops after tho consecutive iterations (not one) which changes Chi square smaller than the minimum deviation decrement

Fixed: Table from Curves failed to add table to new folder, some tooltips were added

Fixed: Inverted scale: log scale labels, scrolling, splitting fit intervals

Fixed: Custom grid lines at 0 position

Fixed: Scale scrollbars bounds did not account for Fit Curves after opening of Fit Plot

Fixed: Multiple selected objects bringing to front and sending to back

Fixed: Ctrl+Ins, Shift+Ins, Shift+Del shortcuts did not work with drawn objects and in text label editing

Fixed: Marker types setting when adding multiple data to Figure

Fixed: Issue on deleting table with Fit Plot data which is used on Figure

Fixed: Incorrect numbers rounding when axes labels multiplier is not equal to 1

Fixed: Fitting with joined parameters when not all joint curves are summed

Fixed: Drawing error bars when showing fit residual

Fixed: Columns rearranging on Linus with Win (Meta) key pressed

Fixed: Critical issue with saving project files with “ (quotes) in some Figure legends

Fixed: Legends format is some cases was not saved in project file

Fixed: Joining parameters of one curve

Fixed: Absence of error for formula a^-b in some cases. Now braces are always required: a^(-b)

Fixed: Measuring distance with scale zoom tool: current axes selection was ignored

Fixed: Undo of changing image size in some cases

Fixed: Filling under spline-connected data curves

Fixed: Critical issue: accounting for y errors from columns in fitting

Fixed: Deleting table with deleted columns with evaluators

Many little improvements and fixes
