Hi Soma,
Thanks for sharing your file.
I was able to clean up the Y-axis labels by replacing:
restick at ttmMajorStride = 25
time_axis_labels(ts&time,res,restick)
with:
restick at ttmMajorStride = 7
time_axis_labels(xDay&time,res,restick)
You can modify the interval between major tick marks as needed.

You may want to try using xDay&time in your time_axis_labels call, although you might also need to adjust the value of restick at ttmMajorStride to account for the smaller time dimension on xDay.
