采用Wiggle曲线表示二维地震剖面图，且根据地震记录中振幅的极性特征，通常将地震数据正值区域以颜色填充显示，负值区仅用曲线显示。(Two dimensional seismic profile is represented by Wiggle curve, and according to the polarity characteristics of amplitude in seismic record, the seismic data is usually filled with color in the positive region, and the negative value area is displayed only by curve.)
