'Timeline\gantt control in winforms approach
I want to create a control that shows a list of activities like in a gantt chart in winforms. I don't want to use any of the non official products out there. The diagram will have to:
- Show the activities as rectangles of different colors. each activity have a start and an end date
- Show an X-axis for the global time line reference (years, months, days)
- Allow the user to zoom in\zoom out, changing the axis accordingly
Where should I start? I first started from scratch with an empty User Control, I can easily draw rectangle as activities but the logic of the axis and the zoom-in zoom-out feature seems too complicated to build.
An alternative could be start from a chart like an horizontal histogram and on that grid and axis draw the activities.
