Example: Inserting a Scatter Chart which will supervise the values of two tags along 7 days.

1. Insert two tags with the names tagA and tagB, type of integer in the Tags sheet. tagB will be an array of 7 values of 1 dimension.

2. Insert a Graphic object with the name Graphic1.

3. Insert two TextBox with the names TextBox1 and TexBox2 and in the Properties Window, field Text, write @tagA in TextBox1 and @tagB in the TextBox2.

4. In Series, insert the 7 days, separated always with a semicolon ";". They could be written as the image below:

5. Insert a Line Chart object, with the name ScatterGraph1.

6. Changes the Type to "Scatter".

7. Insert tagA and tagB in the ScatterGraph1 Series.

8. Now, set the values which the tags will have every day (or the values you want to measure). It can be done using constant values or using an array tag.

9. Configures the Ribbon Settings for the Startup Graphic to be the Graphic1.

10. Save the project (clicking in the , or type CTRL + S) and Run the Application (F5).
