DETAILED DESCRIPTION In the related art mentioned above, various information indicating the state is mainly displayed as numerical information. For this reason, in the related art, there is a case where it is difficult for the operator of the shovel to visually ascertain the progress of the work. According to an embodiment, an operator can visually ascertain the progress of the work. Hereinafter, an embodiment will be described with reference to drawings. First, an overview of a shovel 100 according to the present embodiment will be described with reference to FIG. 1. FIG. 1 is a side view of the shovel 100 as an excavator according to the present embodiment. In FIG. 1, in the shovel 100, an example of a target track BS described below is also illustrated on an upward inclined surface ES to be excavated. The shovel 100 according to the present embodiment includes a lower traveling body 1, and an upper swing body 3 which is swingably mounted on the lower traveling body 1 via a swing mechanism 2. The shovel further includes a boom 4, an arm 5, and a bucket 6 which constitute an attachment, and a cabin 10. The lower traveling body 1 causes the shovel 100 to travel by the pair of left and right crawlers being hydraulically driven by traveling hydraulic motors 1L, 1R (described below, see FIG. 2), respectively. That is, the pair of traveling hydraulic motors 1L, 1R (an example of a traveling motor) drives the lower traveling body 1 (crawlers) as a driven part. The upper swing body 3 is driven by a swing hydraulic motor 2A (described below, see FIG. 2) to swing with respect to the lower traveling body 1. That is, the swing hydraulic motor 2A is a swing driving part that drives the upper swing body 3 as a driven part, and can change the orientation of the upper swing body 3. T
