How to Fix Excel Chart Plotting Data at the Wrong Value or Zero
Question details
The user needs to fix an Excel chart that incorrectly plots a specific value, such as 250, at zero or an inaccurate position on the axis.

- Device & OS
- not provided
- Scenario
- Creating or updating a chart where specific data points are not reflecting their actual numeric values on the graph.
- Observed behavior
- The chart plots positive values (e.g., 250) at zero due to potential issues with data ranges, axis scaling, or series configurations.
Ensure your data cells are formatted as numbers rather than text, as numbers stored as text are often plotted as zero in spreadsheet charts.
Verify Source Data and Series References
Check if the chart is referencing the correct cells and that the data range hasn't shifted to include blank or incorrect rows.
A chart will plot zero if the series is pointing to empty cells or an incorrect column. Re-assigning the exact data range usually resolves this.
Right-click anywhere on the problematic chart and choose 'Select Data' from the context menu.
Under 'Legend Entries (Series)' on the left side of the dialog box, select the data series that is plotting incorrectly and click the 'Edit' button.
Check the 'Series values' input box. Delete the current reference and re-highlight the exact cells containing your numeric data on the worksheet, then click 'OK'.
Adjust Axis Scale Settings
Incorrect minimum or maximum bounds on the vertical axis can severely distort how data points are plotted visually.
Check Cell Formatting and Chart Type
Text-formatted numbers or incompatible chart types (like certain line charts for scattered numeric data) can cause values to plot as zero.
Create and Manage Accurate Charts with WPS Office
WPS Spreadsheet provides an intuitive chart engine that automatically detects data types and applies the correct formats, significantly reducing the chance of plotting errors. It offers robust troubleshooting tools and complete compatibility with Microsoft Excel charts.

Frequently Asked Questions
Why does my spreadsheet chart show a flat line at zero?
This usually happens when the source data cells are formatted as text, or the cells are actually empty. Select your data, apply 'Number' formatting, and re-enter the values, or click the warning prompt to 'Convert to Number'.
How do I stop my chart from plotting empty cells as zero?
Right-click the chart and choose 'Select Data'. Click the 'Hidden and Empty Cells' button at the bottom left of the window. Change the setting from 'Show empty cells as: Zero' to 'Gaps' or 'Connect data points with line'.
Why is the X-axis showing sequential numbers (1,2,3) instead of my data labels?
Your chart might be plotting your axis label column as an actual data series. Right-click the chart, choose 'Select Data', remove the label column from the left 'Legend Entries' list, and add it using the 'Edit' button under 'Horizontal (Category) Axis Labels' on the right.
Does changing the chart type fix values plotting on the wrong scale?
Yes. For example, using a standard Line chart for unevenly distributed numerical data on the X-axis can cause plotting distortion. Switching to an X Y (Scatter) chart forces the software to plot data accurately based on numerical coordinates.
