How to Fix Chart Points Not Matching Data in Excel and Word
Question details
The user needs to correct a chart where the plotted points do not align with the entered numeric data values.
- Product
- Excel, Word
- Device & OS
- not provided
- Scenario
- Creating or editing a chart using numeric X and Y values.
- Observed behavior
- The chart points appear inconsistent with the data because the horizontal axis is treated as categorical text labels instead of numeric X values.
Ensure that your dataset contains pure numeric values for both the X (horizontal) and Y (vertical) axes without hidden text or extra spaces.
Change the Chart Type to an XY (Scatter) Chart
Converting a standard line chart to a scatter chart ensures both X and Y axes are treated as numeric values rather than categories.
A standard line chart distributes the horizontal axis data evenly as categorical labels, ignoring the actual numerical gaps between values. An XY (Scatter) chart correctly maps the exact coordinates for both X and Y values, ensuring proportional and accurate plotting.
Click on the existing chart in your spreadsheet or document to reveal the Chart Tools.
Navigate to the 'Chart Design' tab located on the top ribbon.
Click on the 'Change Chart Type' button in the Type group.
In the dialog box, select 'X Y (Scatter)' from the list of available chart categories.
Choose your preferred scatter chart style (such as with or without connecting lines) and click 'OK'. Then, right-click the chart, choose 'Select Data', and verify that the X and Y ranges are assigned correctly.
Create and Fix Scatter Charts Easily with WPS Office
WPS Office provides a highly compatible and intuitive charting interface, allowing you to plot complex XY scatter charts effortlessly without data alignment issues.
- 1. Open your dataset: Launch WPS Spreadsheet and open the document containing your data.

- 4. Choose your chart style: Select your desired scatter chart style from the drop-down menu to instantly plot accurate coordinates.
Frequently Asked Questions
Why does my line chart show dates or numbers with equal spacing instead of proportional spacing?
Line charts treat the horizontal axis as text labels or categories. Even if your labels are numbers or dates, they are spaced evenly across the axis. To space them proportionally based on their actual mathematical value, you must use an XY (Scatter) chart.
Can I connect the points in an XY Scatter chart with a line?
Yes. When selecting the XY Scatter chart type, you can choose sub-types such as 'Scatter with Smooth Lines' or 'Scatter with Straight Lines' to connect your data points, making it look similar to a line chart but with mathematically accurate X-axis spacing.
How do I switch the X and Y axes in my chart?
Right-click the chart and select 'Select Data'. In the dialog box, click on your data series and choose 'Edit'. You can then manually swap the cell ranges for the 'Series X values' and 'Series Y values'.
Why are my scatter chart points clustered tightly in one corner?
This often happens if your axis bounds are too wide compared to your data range. Double-click the axis to open the Format Axis pane, and manually adjust the Minimum and Maximum bounds to better fit your specific data values.
