Troubleshooting

Plot does not generate

Symptom	Cause	Resolution
Plot area is empty after mapping	Effect Size column not mapped, or Y-axis label column not selected	Confirm Effect Size is assigned in Map Data Columns and a Y-axis label column is selected in Grouping & Selection
Plot area is empty after mapping	Effect Size column contains non-numeric values in all rows	Open Table View to inspect. Replace string-encoded missing values (NA, #N/A, null, –) with empty cells in the source CSV.
File does not upload	File is not comma-separated or lacks a header row	Re-export as CSV from R or Excel. Confirm the first row is column names and delimiters are commas throughout.

Confidence intervals are missing

Symptom	Cause	Resolution
No CI lines visible	Neither CI columns nor SE column is mapped	Map Lower CI + Upper CI, or map an SE column
No CI lines visible	Only one of Lower CI / Upper CI is mapped	Both must be mapped together
CI lines appear for some rows only	SE or CI columns contain missing values for some rows	Rows with missing CI / SE values render as point estimates only. Inspect in Table View.
CI lines visible but look wrong	Lower CI and Upper CI columns mapped in reverse	Swap assignments in Map Data Columns
CI lines visible but look wrong	Wrong X-axis mode for the effect type	Check whether the effect column is a linear β (Beta mode) or multiplicative OR/HR (Odds Ratio mode). Mismatch produces a misleading axis scale.

Label and layout issues

Symptom	Resolution
Row labels overlap	Increase Row Height in Canvas & Display. Reduce Table Text Size in Theme Designer.
Labels clipped at edge	Increase Canvas Padding.
Plot too small for export	Increase Global Zoom. Increase Canvas Padding.
Group headers missing	Enable Show Headers in Grouping & Selection.
Groups not separated visually	Increase Plot Gap in Canvas & Display.

Project / load issues

Symptom	Resolution
Plot does not render after loading project	Column names in the saved mapping no longer match the current CSV headers. Re-map affected fields in Map Data Columns.
Grouping or sorting not applied after load	Grouping column name has changed in the CSV. Re-select in Grouping & Selection.
