swplot.plotatom

plots crystal structure

Syntax

swplot.plotatom(Name,Value)

hFigure = swplot.plotatom(Name,Value)

Description

swplot.plotatom(Name,Value) plots the crystal structure of a SpinW object onto an swplot figure where each atom is shown as a sphere. It can display text labels, control the radius and color of the spheres.

hFigure = swplot.plotatom(Name,Value) returns the handle of the swplot figure.

Name-Value Pair Arguments

'mode'

String that defines the types of atoms to plot:

'all' plot all atoms (default),
'mag' plot magnetic atoms only,
'nonmag' plot non-magnetic atoms only.

'label'

Whether to plot the labels of the atoms, default value is false.

'dText'

Distance between the atom and its text label, default value is 0.1 Å.

'fontSize'

Font size of the atom labels in pt, default value is read using swpref.getpref('fontsize').

'radius'

Defines the atom radius, one of the following strings:

'fix' Sets the radius of all atoms to the value of the radius0 parameter,
'auto' determine the atom radius based on the atom label (e.g. the radius of Cr atom is sw_atomdata('Cr','radius')) and multiply the value by the radius0 parameter.

'radius0'

Constant atom radius, default value is 0.3 Å.

'color'

Color of the atoms, one of the following values:

'auto' all atom gets the color stored in spinw.unit_cell,
'colorname' all atoms will have the same color defined by the string, e.g. 'red',
[R G B] all atoms will have the same color defined by the RGB code.

General paraters

These parameters have the same effect on any of the swplot.plot... functions.

'obj'

spinw object.

'unit'

Unit in which the plotting range is defined. It can be one of the following strings:

'lu' plot range is defined in lattice units (default),
'xyz' plot range is defined in the $xyz$ Cartesian coordinate system in Å units.

'range'

Defines the plotting range. Depending on the unit parameter, the given range can be in lattice units or in units of the $xyz$ Cartesian coordinate system. It is either a matrix with dimensions of $[3\times 2]$ where the first and second columns define the lower and upper plot limits respectively. It can be alternatively a vector with three elements [a,b,c] which is equivalent to [0 a;0 b;0 c]. Default value is [0 1;0 1;0 1] to show a single cell.

'figure'

Handle of the swplot figure. Default value is the active figure handle.

'legend'

Whether to show the plot on the legend, default value is true.

'tooltip'

If true, the tooltips will be shown when clicking on the plot objects. Default value is true.

'shift'

Column vector with 3 elements, all object positions will be shifted by the given value in Å units. Default value is [0;0;0].

'replace'

If true the plot will replace the previous plot of the same type. Default value is true.

'translate'

If true, the plot will be centered, independent of the range. Default value is false.

'zoom'

If true, the swplot figure will be zoomed to make the plot objects cover the full figure. Default is true.

'copy'

If true, a clone of the spinw object will be saved in the swplot figure data which can be retwrived using swplot.getdata('obj'). If false, the handle of the original spinw object is saved which is linked to the input obj and so it changes when obj is changed. Default value is false.

nMesh

Mesh of the ellipse surface, a triangulation class object or an integer that used to generate an icosahedron mesh with $n_{mesh}$ number of additional subdivision into triangles. Default value is stored in swpref.getpref('nmesh'), see also swplot.icomesh.

nPatch

Number of vertices on any patch object that is not the icosahedron, default value is stored in swpref.getpref('npatch').

Output Arguments

hFigure: Handle of the swplot figure.

The name of the objects that are created are 'atom' and 'atom_label'. To find the handles and the corresponding data on these objects, use e.g. sObject = swplot.findobj(hFigure,’name’,’atom’)`.
