Draw Gridlines on Chart

In This Topic

FlexChart provides you the option to draw gridlines in front of or behind the chart data. For this, the control provides AxesOnTop property of FlexChart class to control the appearance of gridlines.

A moving image which shows gridlines on chart data.

Here, in the above use-case, we have used a button event to draw gridlines on chart at runtime.

private void button1_Click(object sender, EventArgs e)
{
  
    // for Odd clicks, ie., if the user clicks for the first time, the third time and so on.
    if (myVar % 2 == 0)
    {
        flexChart1.AxesOnTop = true;
    }
    // for Even clicks, if the user clicks for the second time, the fourth time and so on.
    else
    {
        flexChart1.AxesOnTop = false;
    }
    // Increment myVar.  
    myVar = myVar + 1;
}

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
     ' for Odd clicks, ie., if the user clicks for the first time, the third time and so on.
    If myVar Mod 2 = 0 Then
         flexChart1.AxesOnTop = True
     Else
    ' for Even clicks, if the user clicks for the second time, the fourth time and so on.
         flexChart1.AxesOnTop = False
     End If
    'Increment myVar
    myVar = myVar + 1
 End Sub
