To Free Draw data in a graph:

1. Ensure that the graph is unlocked (you cannot enter data into a locked graph).

   If the graph is locked, the padlock icon above the graph will look like this. If it is unlocked, it will look like this. Click on the padlock icon to change the state of the graph from locked to unlocked or vice-versa.

2. Click the Free Draw icon .
3. Click in the graph at the point on the X axis (time interval) where you want to enter data and on the Y axis (Entities Per Second) at the amount of Entities you want to enter into your model at this time interval.

   For example, if you click the X axis at 00:00:10 and the Y axis at 10 Entities Per Second, then you have entered 10 Entities into the Arrival or Event Profile at the precise time of 00:00:10.

   Note: While you are holding down the left mouse button, a tool-tip displays the time interval and number of Entities.

   
4. If you want to add values for many time intervals, click and hold the left mouse button and move your cursor over the graph. You will see that Entities are added over time as you move the cursor along the X axis and up and down the Y axis.

   Experiment by moving the cursor around the graph. Notice that the graph scrolls horizontally and vertically according to the movement of your cursor.

5. When you are happy with the demand data you have ‘drawn’ into the graph, click the Apply or OK button to save the Arrival or Event Profile.
   Note: The process is slightly different for an Availability Profile as the data only represents ON or OFF. To add data for an Availability profile, click in the graph at the point on the X axis (time interval) where you want to add or change data: for ON, click near the top of the time interval's column and to specify OFF, click near the bottom of it.
