How to Make Square Grid Lines in an Excel Graph (4 Ways)

The following dataset is a Product Delivery Report. We will use this dataset to generate an Excel Graph.

This graph has the traditional rectangular grid. We will use this graph to make square grid lines in an Excel graph.


Method 1 – Changing Axis Scales to Make Square Grid Lines in a Graph

Steps:

  • Press ALT + F11 to open the VBA Editor.
  • Go to Insert Module to create a new module.

  • Insert the following code in the newly opened module:
Sub Changing_Axis_Scales()

  If Not ActiveChart Is Nothing Then
    ChangingAxisScales ActiveChart

  ElseIf TypeName(Selection) = "DrawingObjects" Then
    Dim zshp As Shape
    For Each zshp In Selection.ShapeRange
      If zshp.HasChart Then
        ChangingAxisScales zshp.Chart
      End If
    Next

  Else
    MsgBox "No Chart selected. Please select at least one.", vbExclamation, "Warning!"
  End If

End Sub

Function ChangingAxisScales(zChart As Chart)

  With zChart
    With .PlotArea
      Dim xplotInHt As Double, xplotInWd As Double
      xplotInHt = .InsideHeight
      xplotInWd = .InsideWidth
    End With

    With .Axes(xlValue)
      Dim Ymax1 As Double, Ymin1 As Double, Ymaj1 As Double
      Ymax1 = .MaximumScale
      Ymin1 = .MinimumScale
      Ymaj1 = .MajorUnit
      .MaximumScaleIsAuto = False
      .MinimumScaleIsAuto = False
      .MajorUnitIsAuto = False
    End With

    With .Axes(xlCategory)
      Dim Xmax1 As Double, Xmin1 As Double, Xmaj1 As Double
      Xmax1 = .MaximumScale
      Xmin1 = .MinimumScale
      Xmaj1 = .MajorUnit
      .MaximumScaleIsAuto = False
      .MinimumScaleIsAuto = False
      .MajorUnitIsAuto = False
    End With

    Dim Ytic1 As Double, Xtic1 As Double
    Ytic1 = xplotInHt * Ymaj1 / (Ymax1 - Ymin1)
    Xtic1 = xplotInWd * Xmaj1 / (Xmax1 - Xmin1)
         
    If Xtic1 > Ytic1 Then
      .Axes(xlCategory).MaximumScale = xplotInWd * Xmaj1 / Ytic1 + Xmin1
    Else
      .Axes(xlValue).MaximumScale = xplotInHt * Ymaj1 / Xtic1 + Ymin1
    End If
  End With

End Function

Changing Chart Size to Make Square Grid Lines in Excel Graph

  • Go back to your worksheet and click on your Excel graph to select it.
  • Press ALT + F5 to open the Macro window.
  • Select the macro Changing_Chart_Size and hit the Run button.

The VBA code will run. The code will make your rectangular grid lines square, just like the picture below:

Things to Remember

  • All 4 codes given in this article can perfectly make square grid lines when the values of both the X and Y axes are close to each other.
  • If the value of both X & Y axes differs much, then set manual values instead of using the MaximumScale & MinimumScale properties. Otherwise, the final result will be unusable.
