## Problem

Chart rendering fails due to the “wrong sign in ‘by’ argument” error.

## Cause

This error occurs when the “Upper Range” or “Lower Range” values set in the category settings are inconsistent with the actual range of the data. Specifically:

- The “Upper Range” value is smaller than the minimum value in the actual data range.
- The “Lower Range” value is larger than the maximum value in the actual data range.

For example, if the X-axis uses “Age” (with a data range of 0–100), the following Category settings would cause the error:

- Setting the “Upper Limit” to “-10”.
- Setting the “Lower Limit” to “1000”.

## Solution

Open the Category Setting dialog and set appropriate values to the **Upper Range** and **Lower Range**.
