@mhdajmalik,
Zoom in and Zoom out is not working
Please take a look at this jsfiddle. Setting appropriate minimum and maximum values should work fine.
Line Marker:- I don’t want the whole line, I need a line like what we marked in image 1 (see image-1, marked as option 1)
This feature is not available as of now. However, you can place stripLines at the values you need, as shown in this jsfiddle.
Can I handle zoom in and zoom out by an event (see image-1, marked as option 2)
This feature is not available as of now. However, you can achieve this by changing viewportMinimum and viewportMaximum every time zoom in / zoom out is clicked.
