Plotting routines

Some functionalities are preimplemented to plot dataset in the QT console

h5xplorer.menu_plot.plot_histogram(self, item, treeview, nbins=10)

Plot an histogram of the data

Example:

>>> def context_menu(self,treeview,position):
>>>     all_item = get_current_item(self,treeview,single=False)
>>>     item = all_item[0]
>>>     list_operations = ['Plot Hist']
>>>     action,actions = get_actions(treeview,position,list_operations)
>>>     if action == actions['Plot Hist']:
            plot_histogram(self,item,treeview)

Parameters:

• item (HDF5TreeItem) – treeview item
• treeview (HDF5TreeWidget) – treeview
• nbins (int, optional) – number of bins in the histogram

h5xplorer.menu_plot.plot_line(self, item, treeview)

Plot a line plot of a single item VS its index

Example:

>>> def context_menu(self,treeview,position):
>>>     all_item = get_current_item(self,treeview,single=False)
>>>     item = all_item[0]
>>>     list_operations = ['Plot Line']
>>>     action,actions = get_actions(treeview,position,list_operations)
>>>     if action == actions['Plot Line']:
            plot_line(self,item,treeview)

Parameters:

• item (HDF5TreeItem) – treeview item
• treeview (HDF5TreeWidget) – treeview

h5xplorer.menu_plot.plot1D(self, item0, item1, treeview, plot='line')

Plot a XY line or scatter plot of two items

Note: You must be able to select multiple items to use this method. So you must create the app with:

>>> app = h5xplorer(extended_selection=True)

Example:

>>> def context_menu(self,treeview,position):
>>>     all_item = get_current_item(self,treeview,single=False)
>>>     item0 = all_item[0]
>>>     item1 = all_item[1]
>>>     list_operations = ['Plot1D']
>>>     action,actions = get_actions(treeview,position,list_operations)
>>>     if action == actions['Plot1D']:
            plot1D(self,item0,item1,treeview)

Parameters:

• item0 (HDF5TreeItem) – treeview item for the X data
• item1 (HDF5TreeItem) – treeview item for the Y data
• treeview (HDF5TreeWidget) – treeview
• plot (str, optional) – ‘line’ or ‘scatter’

h5xplorer.menu_plot.plot2d(self, item, treeview)

Plot a map of a 2D data array

Example:

>>> def context_menu(self,treeview,position):
>>>     all_item = get_current_item(self,treeview,single=False)
>>>     item = all_item[0]
>>>     list_operations = ['Plot2D']
>>>     action,actions = get_actions(treeview,position,list_operations)
>>>     if action == actions['Plot2D']:
            plot2D(self,item,treeview)

Parameters:

• item (HDF5TreeItem) – treeview item
• treeview (HDF5TreeWidget) – treeview
