Selecting Entries Selecting an entry in the graph automatically selects the corresponding entry in the table and vice versa regardless of how the data is sorted in the table Use the Ctrl and Shift keys to select contiguous and non contiguous entries When a graph entry is selected and the corresponding entry is not already visible in the table the selected entry is highlighted and scrolled to the top of the table When a table entry is selected and the corresponding entry is not already visible in the graph the selected entry is highlighted and scrolled to the middle of the graph Y Axis Max The Y Axis Max field sets the height of the y axis and is provided primarily to allow the user to deal with the degenerate case of the entire network pausing for a long time When that happens the single token rotation duration that includes the time that the network was paused can dwarf the other token rotation durations to the point of near invisibility Setting the y axis height to an appropriate value pushes the outlier s past the top of the graph while placing the rest of the values below the top of the graph Checking the Auto box causes the y axis height to be adjusted dynamically such that the height of the largest token rotation duration is 95 99 of the height of the graph regardless of whether that token rotation duration is currently visible on the graph The Auto box is checked by default 162 ee frontline Debug Communicat
