This plot shows the history of the correlation (in %), the SNR and DSL ratios.
By default, the number of iterations displayed in the graph is 50.
To change the plot history length, see advanced settings.
In the upper plot, the red curve correspond to the DSL ratio and the green curve to the SNR ratio
In the lower plot, the green curve is the correlation factor and the red curve is the correlation threshold.
Plots are cleared when guiding is started. You can manually clear the plots with the button.
To record the history into a file that can be later on used for analysis, SKG allows to write all Information into a Comma Separated File. Output to CSV can be enabled/disabled while guiding at any time.
By default the scale of the Y axis is automatically adjusted to fit the values displayed in the plots but sometimes to ease the reading it could be good to use a fixed scale.
The vertical toolbar for each plot allows to define how the Y axis will be displayed:
The check box allows to fix use the value displayed under Y axis label as a fixed scale.
To change the Y axis scale you must use the slider bellow the Y axis label.
