A Guide to Building Charts and Pivot Tables for Vendor Comparison
By The USFANS Analytics Team |
In the competitive world of e-commerce, data-driven decision-making is key to securing reliable supply chains. For businesses leveraging platforms like USFANS, analyzing seller performance across critical metrics such as QC quality, refund ratio, and shipping reliability
Step 1: Structuring Your Raw Data
Begin with a well-organized dataset. Your spreadsheet should have clear columns for each metric. A typical structure includes:
Vendor ID
Vendor Name
Month
Units Inspected
QC Pass Rate (%)
Total Orders
Refunds Issued
Refund Ratio (%)
Orders Shipped On Time
Shipping Reliability (%)
VEN101
Alpha Supplies
Jan-2023
1200
98.5
850

VEN102
Beta Goods

92.0

94.3
Tip: Use formulas to calculate key ratios. For example, Refund Ratio (%) = (Refunds Issued / Total Orders) * 100.
Step 2: Creating a Master Pivot Table for Overview
Pivot tables are powerful for summarizing and comparing vendor performance without altering your raw data.
Select Your Data:
Insert Pivot Table:Insert Pivot Table.
Configure Fields:
Rows:Vendor Name
Values:QC Pass Rate (%), Refund Ratio (%), and Shipping Reliability (%). Set the "Summarize by" option to Average.
Filters (Optional):Month
You now have a concise table comparing the average performance of all vendors across your three core KPIs.
Step 3: Building Comparative Charts
Visualizations make trends and outliers immediately apparent. Here’s how to create two effective charts:
Combo Chart for Side-by-Side Comparison
This chart allows you to plot different metrics (e.g., QC Rate and Refund Ratio) for each vendor on the same axis.
Create a new pivot table with Vendor NameQC Pass Rate (%)Refund Ratio (%)
Select the pivot table and insert a Combo Chart
Format the chart: Add axis titles, a legend, and adjust colors for clarity.

Scatter Plot for Correlation Analysis
Use a scatter plot to discover relationships between two metrics, like Shipping ReliabilityRefund Ratio.
Use your raw data or a pivot table to get the vendor-average data points.
Select the two data columns (e.g., Average Shipping Reliability and Average Refund Ratio).
Insert an X-Y Scatter Plot.
Label each point with the vendor name. Add a trendline to see the overall correlation.
