Is it possible to select an area on a graph and to delete data directly from it?

Question

Hi,as written in the message subject, I'm interesting in the possibility of delete data directly from a graph, using two cursors on the x-axis, or selecting directly an area.
In fact I don't know how to link the cursor position to the data position in an array, in fact if I'm able to do this, I can use the cursors to select an interval on the x-axis and then with the help of a control on the front panel, delete the data from the array, and obtain a new graph without the selected area.
Thanks for your kindly attention

Answer 1

I'm assuming from your question that you have an XY graph built from an array, and I'm also assuming the array is sorted by the X axis.
Create a property node for the graph (Right-click on the terminal and select Create>>Property node). Now you can either select the Cursor>>Cursor position and Cursor>>Active cursor properties to get the coordinates of the cursor(s), or you can select the Cursor List property to get an array of clusters that holds the data for all the cursors. Assuming you only have two cursors, you can use a for loop and place an Unbundle by name VI in it to get the cursor position. Now that you have the positions for both cursors, go back to the original array and remove the data that's between these values.
