When working with multiple graphs in DIAdem, it is often necessary to measure the differences between specific points across two curves. For example, you may want to calculate the delta X and delta Y between two points. In this guide, we'll walk you through an easy way to achieve this using the built-in cursor tools in DIAdem VIEW.
 

  1. Open DIAdem VIEW and load the multiple graphs, make sure that all the graphs have the same unit. 
  2. Turn on the Required Cursors. In DIAdem VIEW, you'll need to activate the following cursors which is Frame Cursor, Free Cursor and Position Cursor. These cursors will enable you to easily measure the delta (difference) between two points on different graphs or even within the same graph.
    • The Free Cursor allows you to move freely across the graph, selecting specific points of interest on your curves. Use it to hover over and select the positions where you want to measure the delta X and delta Y.
    • As you move the Free Cursor, the Position Cursor will display the exact X and Y coordinates of the selected point. This is crucial for identifying the specific data values you are comparing.

  1. Identifying Cursor 1 and Cursor 2.
    • The Frame Cursor marks one of the selected points, which will always be referred to as Cursor 1. The blue marking on the frame will indicate its position.
    • The point opposite to Cursor 1, which is highlighted on the graph, will automatically be designated as Cursor 2.

  1. Once both cursors are positioned, DIAdem will automatically calculate and display the differences between the X and Y values for the two points, referred to as:
    • dX-Cursor (the difference in X values between Cursor 1 and Cursor 2)
    • dY-Cursor (the difference in Y values between Cursor 1 and Cursor 2)

Now that you have the delta values, you can interpret the results in relation to your data. For instance:
  • The dX-Cursor reveals the time interval between these points, which is useful for understanding changes over time.
  • The dY-Cursor show how much the temperature has changed between two points.
