Graphing Current State in Stepchart

Question

I've been stuck on this for a few days. I have an object that contains:

  DateTime Start;
  string State; //current state of Item "ON", "D", "SB", "OFF".
  int Duration; // in seconds

I need a step chart that charts the current state of the item by time of day. The chart has time of day along the bottom. States on Y axis 1 and duration on y axis 2. I know the data is getting through, because I have a table below the chart that displays the same data.

I currently have start on Category fields and Duration on secondary axis and Status on regular axis. The main problem is it's not graphing at all.

Answer 1

Figured it out I had to set a switch to get the state to graph correctly on the positions. I then hid the labels and put the correct tags in place. Also when I set the date time for the x axis and set it to increment by hours it set the current day I made that change so when I handed it a day in the past it threw the whole set out as not meeting the criteria.
