DHTMLX Gantt is renowned for its ability to handle large projects<\/a> containing thousands of tasks without compromising performance. While large datasets are rendered smoothly, end-users may need extra time to get to specific parts of the timeline. That\u2019s where a minimap comes in handy. This small but helpful tool can enhance navigation through complex workflows. <\/p>\n

In this tutorial, you will learn how to add a custom minimap to a JavaScript Gantt chart using the API of our Gantt component and pure JavaScript.<\/p>\n

Example of a JavaScript Gantt Chart with a Mini Map<\/h5>\n

Large-scale Gantt charts are notable for extensive task hierarchies and expanded timelines, where some users might get lost in the information maze. In such cases, it is nice to have a navigation tool such as a minimap. It can serve as a compact representation of the entire project (i.e., a bird-eye view of the main Gantt chart), enabling end-users to conveniently look through the whole Gantt chart. To help developers enhance the usability of the JavaScript Gantt component<\/a>, our team prepared a live sample that vividly demonstrates how a minimap can be added to real Gantt projects.<\/p>\n
