WellLogViewer - Discrete logs are displaying incorrectly

[Anders2303]

It seems that the discrete tracks in the well-log viewer are moving their data one step too early; this is mostly notable on discrete logs with low steps, such as the Volve Blocking example data.

The log-viewer is showing H12 at MD [3756, 3821], but should instead be showing it at [3821, 3829]. This offset continues for the entire curve, which stops at 3920, instead of 4130

// volve_blocking_zonelog_logs.json
      "data": [
            [
                3756.3505660463766,
                null
            ],
            [
                3821.5805660478004,
                2 // H12
            ],
            [
                3829.8305660479805,
                3 // H11
            ],
            [
                3832.460566048038,
                4 // H10
            ],
            // ... ...
            [
                3920.150566049952,
                14 // BELOW
            ],
            [
                4130.990566054554,
                14 // BELOW
            ]
        ]

Starts at 3756	Goes to "H11" at 3821	Ends at 3920

I also checked the log-curve layer in the SubsurfaceViewer, and there the logs are correctly displayed. so its likely just an index issue in one of the log viewer utils
