Example Spreadsheet Data

Imagine a spreadsheet tracking quarterly sales data for different products:

Objective: Automatically generate a line chart to visualize the quarterly sales trends for each product.

Code Snippet

Microsoft Excel (VBA):

Sub GenerateSalesChart()
    Dim chartObj As ChartObject
    Dim ws As Worksheet
    Set ws = ActiveSheet
    
    ' Add a chart object
    Set chartObj = ws.ChartObjects.Add(Left:=100, Width:=375, Top:=50, Height:=225)
    
    ' Set chart data and type
    With chartObj.Chart
        .SetSourceData Source:=ws.Range("A1:E4")
        .ChartType = xlLine
        
        ' Customize the chart
        .HasTitle = True
        .ChartTitle.Text = "Quarterly Sales Trends"
        .Axes(xlCategory, xlPrimary).HasTitle = True
        .Axes(xlCategory, xlPrimary).AxisTitle.Text = "Quarter"
        .Axes(xlValue, xlPrimary).HasTitle = True
        .Axes(xlValue, xlPrimary).AxisTitle.Text = "Sales ($)"
    End With
End Sub

Google Sheets (Google Apps Script):

function generateSalesChart() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var chartRange = sheet.getRange("A1:E4");
  
  // Create and customize the chart
  var chart = sheet.newChart()
     .setChartType(Charts.ChartType.LINE)
     .addRange(chartRange)
     .setPosition(5, 6, 0, 0)
     .setOption('title', 'Quarterly Sales Trends')
     .setOption('hAxis', {title: 'Quarter'})
     .setOption('vAxis', {title: 'Sales ($)'})
     .build();
  
  // Add the chart to the sheet
  sheet.insertChart(chart);
}

After running this macro, a line chart titled "Quarterly Sales Trends" will be created, plotting the quarterly sales for each product. This chart visually demonstrates the sales growth over the year, making it easier for stakeholders to understand performance trends at a glance.

By automating the creation and formatting of charts, the Chart Generator macro significantly enhances the efficiency of report preparation and the impact of presentations, allowing users to focus more on analysis and less on manual chart construction.
