A volcano plot uses log2 fold change on the X axis and p-value significance on the Y axis.
Prepare a directly mappable table
Volcano plots need one log2FC column and one p-value or adjusted p-value column.
The example table uses volcano_demo_data with 50 rows and 6 columns. Three columns are mapped: log2FC, p_value, and gene label.

Create a volcano plot
In the Create Figure panel, map the log2FC column, significance column, and optional label column. SmartPlot creates the volcano plot from those mapped columns.
Step 1
Choose analysis data
Confirm the data range, then choose a new figure or add the plot to an existing figure.
