qcodespp.plotting.RemoteQtPlotWidgets.make_rgba(colorscale)

qcodespp.plotting.RemoteQtPlotWidgets.one_rgba(c): convert a single color value to (r, g, b, a) input can be an rgb string ‘rgb(r,g,b)’, ‘#rrggbb’ if we decide we want more we can make more, but for now this is just to convert plotly colorscales to pyqtgraph tuples

qcodespp.plotting.RemoteQtPlotWidgets.qtapp

class qcodespp.plotting.RemoteQtPlotWidgets.PlotTrace(*args, **kargs)

Bases: pyqtgraph.PlotDataItem

PlotDataItem with benefits

delete() update() - check if data has been updated - call set_data() with the updated data

setData(*args, **kwargs): Clear any data displayed by this item and display new data. See __init__() for details; it accepts the same arguments.

update_data()

class qcodespp.plotting.RemoteQtPlotWidgets.PlotLinecuts(*args, **kargs)

Bases: pyqtgraph.PlotDataItem

PlotDataItem with benefits

delete() update() - check if data has been updated - call set_data() with the updated data

setData(*args, **kwargs): Clear any data displayed by this item and display new data. See __init__() for details; it accepts the same arguments.

update_data()

class qcodespp.plotting.RemoteQtPlotWidgets.PlotImage(*args, **kwargs)

Bases: pyqtgraph.ImageItem

ImageItem with benefits

delete() update() - check if data has been updated - call set_data() with the updated data

x_data = None

y_data = None

z_data = None

setImage(*args, **kwargs)

Updates the image displayed by this ImageItem. For more information on how the image is processed before displaying, see makeARGB().

For backward compatibility, image data is assumed to be in column-major order (column, row) by default. However, most data is stored in row-major order (row, column). It can either be transposed before assignment:

imageitem.setImage(imagedata.T)

or the interpretation of the data can be changed locally through the axisOrder keyword or by changing the imageAxisOrder global configuration option

All keywords supported by setOpts() are also allowed here.

Parameters

image: np.ndarray, optional

Image data given as NumPy array with an integer or floating point dtype of any bit depth. A 2-dimensional array describes single-valued (monochromatic) data. A 3-dimensional array is used to give individual color components. The third dimension must be of length 3 (RGB) or 4 (RGBA).

rect: QRectF or QRect or array_like, optional

If given, sets translation and scaling to display the image within the specified rectangle. If array_like should be the form of floats [x, y, w, h] See setRect()

autoLevels: bool, optional

If True, ImageItem will automatically select levels based on the maximum and minimum values encountered in the data. For performance reasons, this search subsamples the images and may miss individual bright or or dark points in the data set.

If False, the search will be omitted.

The default is False if a levels keyword argument is given, and True otherwise.

levelSamples: int, default 65536

When determining minimum and maximum values, ImageItem only inspects a subset of pixels no larger than this number. Setting this larger than the total number of pixels considers all values.

update_data()

class qcodespp.plotting.RemoteQtPlotWidgets.PlotDock(*args, **kwargs)

Bases: pyqtgraph.dockarea.Dock

Dock with benefits

contains a list of traces
turns on and of Hist item

setGeometry() clear() save() to_matplolib()

theme = ((60, 60, 60), 'w')

grid = 20

dock_widget

hist_item

plot_item

legend

set_cmap(cmap=None, traces=None)

add_item(*args, pen=False, **kwargs): Shortcut to .plot_item.addItem() which also figures out 1D or 2D etc.

set_labels(config=None)

close(): Remove this dock from the DockArea it lives inside.

clear()

class qcodespp.plotting.RemoteQtPlotWidgets.QtPlot(*args, title=None, figsize=(1000, 600), figposition=None, window_title=None, theme=((60, 60, 60), 'w'), parent=None, cmap='viridis', **kwargs)

Bases: PyQt5.QtWidgets.QWidget

auto_updating = False

theme = ((60, 60, 60), 'w')

area

clear()

closeEvent(event): Make sure all dock-widgets are deleted upon closing or during garbage- collection. Otherwise references keep plots alive forever.

add_dock(title=None, position='right', relativeto=None)

Add a new dock to the current window.

Args:

title (str):: Title of the dock
position (str):: ‘bottom’, ‘top’, ‘left’, ‘right’, ‘above’, or ‘below’
relativeto (DockWidget, int):: If relativeto is None, then the new Dock is added to fill an entire edge of the window. If relativeto is another Dock, then the new Dock is placed adjacent to it (or in a tabbed configuration for ‘above’ and ‘below’).

add(*args, subplot=0, **kwargs)

qcodespp.plotting.RemoteQtPlotWidgets.plot
