Wrong task date range filter in Gantt charts (does not show all the tasks)

opened 07:15AM - 19 Feb 23 UTC

### Description Current behavior is has incorrect date filter. Now it checks if… task only **start date** is in the selected date range, but should check if task date (from **start till the end**) intersects with the selected date range. Problem: Gantt chart is not displaying tasks that should be visible. ### Vikunja Frontend Version 0.20.3 ### Vikunja API Version 0.20.1 ### Browser and version All ### Can you reproduce the bug on the Vikunja demo site?

### Description In the Gantt view, if the start date of a task is earlier than …the start date of the selected date range, the task is not rendered in the Gantt chart. However, if the task's end date falls within the date range, the task should still be visible in the chart. This behavior means that for long-running tasks (e.g., tasks that last two months), once the task's start date has passed, the task will no longer be displayed in the table, even if its end date falls within the visible date range. ### Vikunja Version v0.24.4 ### Browser and version Google Chrome Version 130.0.6723.117 (Official Build) (64-bit) ### Can you reproduce the bug on the Vikunja demo site? Yes ### Screenshots ![vikunja issue](https://github.com/user-attachments/assets/84146287-f741-4d56-89cc-26e2a1cc47b0) In the second screenshot, the start date of the date range is moved forward by one day, causing the task 'Test' to disappear.

### Description When looking at tasks in the Gantt view, if you have a task tha…t starts before the start date of the view, but ends >= that start date of the view, it doesn't show in the Gantt chart. This is confusing, since the task is still "open". I would expect it to show up starting at the far left of the Gantt chart, and extending until it's end date (which may be within the Gantt view date range, or after it, in which case it would extend to the far right of the Gantt chart. ### Vikunja Version Latest (I assume) -- on try.vikunja.io ### Browser and version Brave 1.74.51 Win 10 ### Can you reproduce the bug on the Vikunja demo site?
