Hi,

We are using Infra version 6.3.
We use GanttChart to display Day\Week\Month wise tasks with in a ASP.Net page.

Problem: 
Tasks within the chart is not exactly aligned to the corresponding Start and End days (in X2 axis). 
Tasks are overlapping the Days grid lines and sometimes tasks stop before reaching the End date Grid line.
Also last grid line is not drawn.

Steps to reproduce the issue:
1.  Create a DB table as required for Gantt Chart
2.  Drag a Ultra chart to the design and paste the below source in Code behind page to set the properties of the Chart Control.

Please look into the below Source and help me out of this issue.

Thanks,
Anandhev
