6.2.1. itom.figure.plot

figure.plot(data[, areaIndex, className, properties]) → plots an existing dataObject, pointCloud or polygonMesh in the current or given area of this figure

The style of the plot depends on the object dimensions.

If no ‘className’ is given, the type of the plot is chosen depending on the type and the size of the object. The defaults for several plot classes can be adjusted in the property dialog of itom.

You can also set a class name of your preferred plot plugin (see also property dialog of itom). If your preffered plot is not able to display the given object, a warning is returned and the default plot type is used again. For dataObjects, it is also possible to simply set ‘className’ to ‘1D’, ‘2D’ or ‘2.5D’ in order to choose the default plot type depending on these aliases. For pointCloud and polygonMesh only the alias ‘2.5D’ is valid.

Every plot has several properties that can be configured in the Qt Designer (if the plot is embedded in a GUI), or by the property toolbox in the plot itself or by using the info() method of the corresponding itom.uiItem instance.

Use the ‘properties’ argument to pass a dictionary with properties you want to set to a certain value.


data : {DataObject}

Is the data object whose region of interest will be plotted.

areaIndex: {int}, optional :

Area number where the plot should be put if subplots have been created

className : {str}, optional

class name of desired plot (if not indicated default plot will be used, see application settings)

properties : {dict}, optional

optional dictionary of properties that will be directly applied to the plot widget.


plotHandle: {plotItem} :

Handle of the subplot. This handle is used to control the properties of the plot, connect to its signals or call slots of the subplot.
