By using ANKO Gantt chart, You can improve the efficiency of the work.

Didn’t you think that using Redmine Gantt chart is something troublesome or inconvenient? There are no edit function, but only view functions in Redmine Gantt chart, so when you want to create or correct an issue, you should move another page form there. That had very low efficiencies.

ANKO Gantt chart is the plugin to add creating and editing function to normal “Redmine Gantt chart”. You can use ANKO Gantt chart to create a WBS very easily, intuitively without moving from a Gantt chart page. You can register WBS, Schedule management easily without any stress.


Main functions



When you click “new issue” in Gantt chart page, you can register “new issue” on the same page-Gantt chart page. You can quickly and efficiently register a new issue by checking a Gantt chart.


When you click the “To register subtask” icon next to the issue name, you can register “subtask” on the same page (Automatically, the parent task number is put in the Parent task Field).


You can register a hierarchical issue like as WBS efficiently, because you can register a subtask immediately while checking the Gantt chart.



You can change the issue(title, contents, status and the related issue etc) by clicking the issue title. You took time and effort to change the issue continuously in Gantt chart page of Redmine, because you should move to the issues detail page to change, after registering, you have to move to the Gantt chart page once again.


But if you use ANKO Gantt chart, you can change the issue only in Gantt chart page, so you can operate intuitively.


CHANGE START AND DUE DATES by mouse drag and Mass update

You can change the date of the Gantt chart with the mouse drag. While dragging the Gantt chart, the color of the Gantt chart is changed to transparent color, so you can easily compare with the original Gantt chart. You can move Gantt chart side to side, or change the width of it.


It is possible to improve work efficiency and to suppress unnecessary log generation by collective Mass update function. After selecting “Mass update”, dragging the Gantt chart by mouse will not change yet,  it will show how many changes to the information until now. When clicking “## Update”, Gantt charts is updated all at once.
