I'm trying to create a stacked bar chart that displays two classes of data on a sequential timeline instead of grouping each data type into single box. Basically, I want to show the amount of time spent "watching movies" or "playing games" with each activity type represented sequentially on the timeline, and with size of the bar relative to the time spent for that interval. This data is per-day, and the chart needs to display several days worth of activity. Hopefully the attached image can explain much better. Any help or pointers in other directions is appreciated.
I think your best bet is to start with a Gantt chart approach - Creating a Gantt Chart for Small Time Increments | Tableau Software
