This is in visual studio, visual basics framrwork $4\mathrm{.}7\mathrm{.}2$

how do i create a graph functionality in my application that reads Weight, BodyFat, and BMI data from the arrResults array and displays it on a chart. The chart should update when the user presses a "Check" button for any of these metrics, plotting the selected metric on the Y$-$axis against dates on the X$-$axis.

Integrate this graph functionality into my existing data structures and form. The graph should dynamically update when the user selects a metric $($Weight$,$BodyFat$,$ or BMI$)$and display the corresponding values from the results file in a line chart format. The form will have buttons for each metric to trigger the update.

Data structures:

Module Data$\_$Structure

$$ Public arrCustomer$(999)$As Customer 'stores all the student records from the file

$$ Public indexCustomer As Integer $=0$

$\text{'}$so you dont go into empty records

$$ 'Customer record structure

$$ Structure Customer

$$ Dim CustomerID As String

$$ Dim firstname As String

$$ Dim lastname As String

$$ Dim phoneNUM As String

$$ End Structure

$$ 'trainer

$$ Public arrTrainer$(999)$As Trainer 'stores all the trainer records from the file

$$ Public indexTrainer As Integer $=0\text{'}$dont go into empty records

$$ 'Trainer record structure

$$ Structure Trainer

$$ Dim TrainerID As String

$$ Dim Tfirstname As String

$$ Dim Tlastname As String

$$ Dim Tphonenum As String

$$ End Structure

$$ 'results

$$ Public arrResults$(999)$As Result 'stores all the results records from the file

$$ Public indexResults As Integer $=0\text{'}$dont go into empty records

$$ 'Result record structure

$$ Structure Result

$$ Dim WeightID As String

$$ Dim BodyFatID As String

$$ Dim BMIID As String

$$ End Structure

$$ Public arrSession$(999)$As TrainingSession

$$ Public IndexSession As Integer $=0$

$$ Structure TrainingSession

$$ Dim SessionID As String

$$ Dim SessionDate As Date

$$ Dim Duration As Integer

$$ End Structure

End Module

File Handler:

Module File$\_$Handler

$$ Const fileCustomer As String $="$customer$.$txt$"\text{'}$filename constant

$$ Const fileTrainer As String $="$trainer$.$txt$"\text{'}$filename constant

$$ Const fileResult As String $="$result$.$txt$"\text{'}$filename constant

$$ 'reads data from the file
