dynamic chart based on combo box

Hello,

I am trying to create a dynamic chart based on values in a combo box (whenever the user clicks on the value in the combo box, the chart changes).

The data consists of three columns X, Y and Z.
The combo box includes the values of all X.
Whenever a value of X in the combo box is chosen, I need my chart to show Y and Z.
For example if in the combo box the user chooses -353.692, I need my chart to show the values of Y and Z (like the chart in the file attached).
Any help pls?
