mjolnir.plotting.live_view#

This module provides several live-plotting classes that use qutil.plotting.live_view.

Classes

ImageLiveView(station[, exposure_time, ...])

Show a video of CCD live images.

PowerLiveView(station[, display_duration, ...])

Monitor readings from the power meter.

SpectrumLiveView(station[, exposure_time, ...])

Show a video of CCD live spectra.

TimeTaggerLiveView(station, channels[, ...])

class mjolnir.plotting.live_view.ImageLiveView(station, exposure_time=0.1, subtract_background=True, data_rate=False, light_source='laser', horizontal_scale='wavelength', read_mode='image', read_mode_settings=None, update_interval_ms=1000, autoscale=True, autoscale_interval_ms=1000, show_fps=False, useblit=True, style=('dark_background', 'fast'), img_kw=None, fig_kw=None, log_level=None)[source]#

Bases: _CcdMixin, BatchedLiveView2D

Show a video of CCD live images.

Parameters:

  • station (Station) – The logical station in which the ExcitationPath instrument lives.

  • exposure_time (float) – The (maximum) exposure time.

  • subtract_background (bool) – Subtract a background image from the data before displaying.

  • data_rate (bool) – Plot the count rate instead of the total number of counts.

  • light_source (Literal['laser', 'white_light']) – Use the white light or the laser.

  • horizontal_scale (Literal['energy', 'wavelength']) – Show energy or wavelength on the bottom axis.

  • read_mode (Literal['image', 'random track', 'multi track']) – Use image, random track, or multi track mode.

  • read_mode_settings (Any | None) – Read mode settings to apply for data acquisition.

  • update_interval_ms (int)

  • autoscale (bool | None)

  • autoscale_interval_ms (int | None)

  • show_fps (bool)

  • useblit (bool)
