What am I doing wrong here?

Disclaimer: I am a canvas newbie.

So here I am trying to plot some data. Data preview looks good. But in visualisation the Y-Axis is acting up. No values are plotted. On X-Axis time is getting plotted all right.
P.S: I had to erase some of the values from the figures.

Is it possible for you to share or mock any of the data you are using? It's hard to troubleshoot without it.
