Line Chart with Time as Y Axis

ShaikRafi , I doubt you can take time on y axis. You can use time in second or minute

Hi , ShaikRafi 

Currently, it is difficult to contain time values at the y-axis of Power Bi line chart.

As a workaround, you can try R visual. Please check the solutions in similar threads below for more details.
