First find out where the height is coming from. Do this in your (Firefox) browser’s inspector (press F12) and select the dom-element of the Gantt chart. Then in computed you can find which class sets the height:
Hi Tim,
I have found the class and adjusted the height on the browser, it works fine.
I have provided class and height on the Gantt chart, but it's not working.
Please confirm that I am providing class and height in the correct way or there is any other way to provide class and height. (Image attached)
