Title Not Rendering After Manually Setting Padding

Problem Description

When using AntV G2 to render charts, manually setting the padding can cause the chart title to not render properly or disappear entirely.

Cause Analysis

G2 dynamically calculates the space required for all components by default, but once a fixed padding value is specified, this automatic adjustment logic is skipped, which may lead to incomplete rendering of the components.

Solutions

There are two ways to resolve this issue:

1. Use the Default Layout (Recommended)

Allow G2 to automatically calculate the optimal spacing to ensure that all components are rendered correctly:

chart
  .interval()
  .encode('x', 'category')
  .encode('y', 'value')
  .encode('color', 'type');

2. Set Padding Correctly

If you must manually set the padding, make sure to reserve enough space for dynamically generated components:

chart
  .padding(50)
  .interval()
  .encode('x', 'category')
  .encode('y', 'value')
  .encode('color', 'type');

Notes

• When manually setting padding, it is recommended to debug and find the appropriate values.
• Consider the space requirements for titles, legends, and other components.
• If a specific layout is not required, it's better to use G2's automatic layout system.
