How to Fix an Excel Line Chart That Does Not Start at the First Data Point
Question details
The user needs to fix a line chart where horizontal lines bend toward the lower-left corner and fail to start at the first plotted date.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Creating or editing a combo chart with columns and horizontal line series.
- Observed behavior
- The line bends toward the lower-left corner instead of starting properly at the first plotted date, usually due to incorrect series name and value references.
Ensure your dataset has clear, distinct headers for each column and verify that there are no empty cells at the beginning of your plotted data range.
Correct Overlapping Series Name and Values References
Resolve the issue by ensuring the Series Name cell reference does not overlap with the Series Values range in the Select Data Source dialog.
When creating charts in Excel, assigning the exact same cell reference to both a Series Name and the beginning of the Series Values can confuse the chart formatting. Separating the name from the actual numeric data range prevents lines from bending off-target or missing the first data point.
Right-click on the affected chart and select 'Select Data...' from the context menu to open the Select Data Source dialog box.
Under the 'Legend Entries (Series)' list on the left, click on the problematic line series to highlight it, then click the 'Edit' button.
Examine the 'Series Name' and 'Series Values' text boxes. If your data values start at cell E5, ensure the Series Name points to a different cell, such as E4. Adjust the references so they do not overlap.
Click 'OK' to close the Edit Series window, and 'OK' again to close the Select Data Source window. Check the chart to ensure the line now properly starts at the first plotted date.
Verify Data Range and Axis Settings
Ensure the chart includes the complete data range and check if the series is incorrectly plotted on a secondary axis with different scaling.

WPS Spreadsheet offers an intuitive interface to manage chart data sources, making it easy to fix series overlaps and create professional visualizations without missing data points.
- 1. Open your data: Launch WPS Spreadsheet and open your workbook containing the chart data.
- 2. Insert or Edit Chart: Go to the Insert tab to create a new chart, or click an existing chart and choose 'Select Data' from the Chart Tools tab.
- 3. Adjust Series References: In the Edit Series window, independently select the correct header cell for the Series Name and highlight the exact numeric data range for Series Values.
Frequently Asked Questions
Why does my Excel line chart drop to zero at the beginning or end?
This usually happens if you have blank cells in your data range. You can fix this by adjusting the data range to exclude empty cells or by modifying the 'Hidden and Empty Cells' settings in the Select Data window to connect data points with a line instead of plotting zeros.
How do I align my line chart with a secondary axis correctly?
Double-click the line series to open the Format Data Series pane. Under Series Options, select 'Secondary Axis'. Ensure that the scale (minimum and maximum bounds) of the secondary axis aligns correctly with your primary axis if you need the data points to match visually.
Can I stop Excel from changing dates on my horizontal axis, which creates gaps?
Yes. Right-click the horizontal axis and select Format Axis. Under Axis Options, change the Axis Type from 'Automatically select based on data' or 'Date axis' to 'Text axis'. This prevents Excel from plotting gaps for missing dates chronologically.
