Drawing graphs

Graphs in VisiData can be used to visualise the relationship between numeric dependent variables vs a numeric independent variable. Optionally, a second independent variable, which is categorical, adds an additional colored scatter plot for each category.

This example uses the file StatusPR.csv.

How to graph a single column

Press ! to set a column as the x-axis. This column must be numeric.
Set that column to a numeric type by pressing # (int), % (float), $ (currency), or @ (date).
Optional: Press ! on a categorical key column to add it as an additional independent variable.
Set the type of the column you wish to set as the dependent variable with a numeric type.
Press . (dot=plot) on that column.

How to graph multiple columns

Press ! to set a column as the x-axis. This column must be numeric.
Set that column to a numeric type.
Optional: Press ! on a categorical key column to add it as an additional independent variable.
Type all of the columns you wish to set as the dependent variables with a numeric type.
Press - (dash) to hide any numeric columns you don't wish graphed.
