daplis_rtp.gui.MZI_tab module
This script generates the tab for online photon count plotting.
Two pixels are chosen for which the photon count registered is plotted side by side. Can be used in the Mach-Zehnder interferometer setup to follow the changes of the photon counts in two pixels, or in other setups for checking the stability.

Creation of the tab.
The tab is generated with a ‘Browse’ button along with a line edit field for choosing/inserting the address of the data file to plot. Combo boxes for LinoSPAD2 daughterboard number and the firmware version are generated. A check box for applying and a button for undoing the mask are generated. A spin box for the number of timestamps per pixel/TDC per cycle is provided. A check box for switching between a linear and a logarithmic scale of the plot is also provided. Buttons ‘Refresh plot’ for refreshing the plot and ‘Start stream’ for plotting the last file found are created. Two sliders for the left x-axis left limit and lower y-axis limit are provided.
