Does the subject want to ask "What happened to the zebra crossing map of version 20 19?" The reasons for the dislocation of zebra crossing map in version 20 19 are incorrect data input, incorrect time scale setting and incorrect dependency setting between tasks.

1. Data input error: If the input time or task information is incorrect, the crossplot will be misplaced. For example, when you enter the start and end times, you may make an input error or ignore some tasks, resulting in incorrect display of the crossplot.

2. Incorrect time scale setting: the time scale of the crossing chart of the progress plan is one of the key factors. If the time scale is set incorrectly, it will lead to inaccurate display of the crossing map. For example, if the timescale is set to months, but the start and end times of tasks are defined according to weeks or days, the bar chart will display unevenly.

3. Incorrect dependency settings between tasks: If the dependency settings between tasks are incorrect, the bar graph will be misplaced. For example, if the end time of a task is earlier than the end time of its predecessor, the bar graph will be displayed incorrectly.
