Create a Safe Operating Envelope Chart in WPS Office Spreadsheet
Question details
The user needs to display a safe operating envelope and current aircraft balance points in a weight-and-balance spreadsheet so it is easy to see whether each current point falls inside or outside the approved boundaries.
- Product
- WPS Office Spreadsheet
- Device & OS
- not provided
- Scenario
- A weight-and-balance spreadsheet requires a chart that compares current aircraft balance points to approved minimum and maximum boundary values.
- Observed behavior
- The desired chart uses an XY scatter view with straight boundary lines and labeled current points to clearly identify inside or outside conditions.
Prepare the weight and balance data in separate columns, and add adjacent columns for the minimum and maximum envelope boundary values. Make sure the boundary points are ordered from left to right on the chart so the envelope forms a proper closed shape.
Create a Safe Operating Envelope Chart with an XY Scatter Chart
Use this method when you need to compare current weight-and-balance points against approved envelope boundaries in WPS Office Spreadsheet.
An XY scatter chart plots numeric coordinates on both axes, which is ideal for weight-and-balance data. Using separate series for the minimum and maximum boundaries creates the envelope lines, while the current-data series shows each aircraft balance point.
In WPS Office Spreadsheet, enter weight values in one column and balance values in the next column. Add two more columns for the minimum and maximum boundary values, ordered in the same left-to-right sequence as the envelope.
Select the current-data columns together with the boundary columns, then click Insert > Scatter > Scatter with Straight Lines.
Right-click a boundary series, choose Format Data Series, and set Marker Fill or Marker Options to None so the envelope appears as straight lines without markers.
Right-click the current-data series, choose Add Data Labels, and then format the labels to show the point name, value, or another identifier for each aircraft balance point.
Read the chart to confirm whether each current point lies inside the envelope formed by the boundary lines. If needed, adjust the axis minimum, maximum, or scale from the Axis Options panel.
Create a Safe Operating Envelope Chart in WPS Office Spreadsheet
Use WPS Office Spreadsheet to build an XY scatter chart with envelope boundary series and current balance points, then visually verify whether each point is inside the safe operating envelope.
- 1. Open the workbook in WPS Office Spreadsheet: Download and install WPS Office, open the weight-and-balance workbook, and go to the sheet that contains the weight, balance, and boundary data.
- 2. Insert the scatter chart: Select the current-data and boundary columns, then click Insert > Scatter > Scatter with Straight Lines.
- 3. Format the envelope and current points: Remove markers from the boundary series and add data labels to the current balance points so the safe envelope is easy to read.
- 4. Save as an Excel-compatible workbook: Click Menu > Save As and choose .xlsx format to keep the chart compatible with Excel users.
Frequently Asked Questions
What chart type is best for showing a safe operating envelope in WPS Office Spreadsheet?
Use an XY Scatter chart with straight lines. It plots weight and balance coordinates on numeric axes and can combine envelope boundary series with current balance points.
How do I make the envelope series appear as a clean line instead of markers?
Right-click the boundary series, choose Format Data Series, and set Marker Fill or Marker Options to None. You can also adjust the line color and width in the same panel.
Can I add labels to each current aircraft balance point?
Yes. Right-click the current-data series, choose Add Data Labels, and then format the labels to show values, series name, or a custom identifier range.
Will this chart work with an existing Excel weight-and-balance spreadsheet?
WPS Office Spreadsheet opens and saves .xlsx files, so you can open the existing workbook, create the envelope chart, and continue using it in Excel.
