- The user aims to understand the dataset's variables and structure to create accurate and meaningful charts.
Before creating any charts, ensure you have a clear understanding of the dataset's origin and identify the main question your visualization needs to answer.
Step-by-Step Approach to Analyzing and Visualizing Data
Follow a structured process to make sense of new datasets, clean the values, and pick the right chart type to communicate your findings.
Jumping straight into chart creation with messy data often leads to confusing or inaccurate visualizations. It is crucial to inspect, understand, and clean your data first. Collaborating with the original data owner can also provide necessary context.
If the data is unfamiliar, ask the person who provided it what each column represents, how the data was collected, and whether it has already been grouped or summarized.
Look at the rows and columns to identify the main variables. Check whether the data represents dates, categories, numerical values, or percentages.
Remove any blank rows, delete duplicates, and ensure that numbers and dates are formatted correctly. Consistent formatting is required for software to generate accurate charts.
Decide what message you want to convey. Determine if you are trying to show a comparison between categories, a trend over time, a data distribution, or a composition (parts of a whole).
Select a chart type that matches your goal. Use a Line chart for trends, a Bar or Column chart for comparisons, and a Pie chart for composition.

Frequently Asked Questions
How do I choose the right chart for my data?
Choose a Line chart for showing trends over a period of time, a Bar or Column chart for comparing different categories, a Pie chart for illustrating parts of a whole, and a Scatter plot for identifying relationships between two numerical variables.
What should I do if my dataset has missing values?
Depending on your analysis goals, you can either delete the rows with missing data if they are insignificant, or fill them in using averages, zeros, or estimations. In WPS Spreadsheet, you can use the 'Go To' feature to quickly find and manage blank cells.
Why is my chart not displaying the data correctly?
This usually happens when the source data is not formatted properly. Ensure that your numbers are formatted as actual Number values (not Text) and that dates are recognized as Date values before you generate the chart.
