5 | * class for creating matrix like timeframes for items * |
---|
6 | * * |
---|
7 | * this matrix is having the days of actual month in the x-axis and the * |
---|
8 | * items, which could be projects, in the y-axis. * |
---|
9 | * You will see a top-down view of all items and their associated * |
---|
10 | * timeframes. You probably saw this in projectmanagement apps * |
