Method for Making a Pareto Chart

1. Open the sample database Northwind.mdb (or NWIND.MDB in version 2.0).
2. Create the data source for the chart as follows:
   
   
   1. Copy and paste the Sales By Category query to a new query. Name this new query qrySalesbyCategory.
   2. Open the qrySalesbyCategory query in Design view. Delete the CategoryID field and the ProductName field. (In Microsoft Access 2.0, delete the Product Name field.) Set the Sort order of the ProductSales field to Descending.
   3. Change the query to a Make Table query. In the Make Table dialog box, type tblSalesbyCategory in the Table Name box.
   4. Save the query and run it. Accept the message to paste rows to a new table.
   5. Close the query.
   6. Create a new query. Add the tblSalesbyCategory table to the query. Drag the CategoryName field to the QBE grid.
   7. Make a calculated field to the right of CategoryName. Name it ProductSalesTotal. Set it equal to the ProductSales field from the tblSalesbyCategory table:
      

                ProductSalesTotal: [ProductSales]
      								

   8. Make another calculated field to the right of ProductSalesTotal. Name it CumPct. Set this field equal to the following.
      
      NOTE: In the following example, an underscore (_) at the end of a line is used as a line-continuation character. Remove the underscore from the end of the line when re-creating this example.
      

                DSum("[ProductSales]","tblSalesbyCategory","[ProductSales]>=" _
                & [ProductSalesTotal] _
                & "")/DSum("[ProductSales]","tblSalesbyCategory")

   9. Save the query and name it qrySalesbyCategoryPareto. Close the query.
3. Create a Chart Form as follows:
   
   
   1. Create a new form using the Chart Wizard based on the query qrySalesbyCategoryPareto. (In Microsoft Access 2.0, in the Select a Table/Query box, select the qrySalesbyCategoryPareto query. Click the Form Wizards button. In the Form Wizards box, select Graph, and then click OK.)
   2. Move all three available fields to the Fields For Chart box. Click Next. (In Microsoft Access 2.0, move all three available fields to to the Fields For Chart box. Click Next. Select Category Name as the field to be on the horizontal axis, and click Next. Select both remaining fields to appear on the legend. Accept the default totaling method of Add(Sum) the numbers, and click Next.)
   3. Select the Line Chart as the type of chart to use. Click Next.
   4. Double-click SumofProductSalesTotal, and select None for Summarize. (In Microsoft Access 2.0, skip this step.)
   5. Click the CumPct field, and drag it underneath the ProductSalesTotal field. (Do not replace ProductSalesTotal, but add CumPct to the Data section.) (In Microsoft Access 2.0, skip this step.)
   6. Double-click the SumofCumPct field, and select None for Summarize. Click Next. (In Microsoft Access 2.0, skip this step.)
   7. For the chart title, type Sales by Category - Pareto, and then click Finish. (In Microsoft Access 2.0, type the chart title Sales by Category - Pareto. Click Modify the design of the form or the graph, and then click Finish.)
4. Update the form's design view with the graph's actual data:
   
   
   1. Set the graph's Enabled property to Yes and Locked property to No.
   2. Close and save the form.
   3. Open the form in Form view.
   4. Click the Graph object so it has the focus.
   5. On the Edit menu, point to Chart Object and then click Open to start Microsoft Graph. Note that Microsoft Graph displays the actual data.
   6. On the File menu, click Update.

   8. Close the form.
5. Modify the Chart Design as follows:
   
   
   1. On the View menu, click Form Design. (In Microsoft Access 2.0, the form will already be open in Design view.)
   2. Using the right mouse button (right-click), click the chart in Form design, click Chart Object, and then click Edit.
