y-axis inverted or logarithmic

[Photelegy]

1. How can I invert the y-axis (useful for "showing" the relative height based of the air-pressure of smartphones)?
   So that 940hPa would be on top and 970hPa would be on the bottom.
   

2. How can I make the y-axis logarithmic (useful for light-sensor [lux] or corona-cases)?
   So that I can see the small changes better (without zooming) because of the logarithm.

1. Reverse axis:

layout:
  yaxis:
    autorange: reversed

2. Log Scale

layout:
  yaxis:
    type: log

3. Pro tip ;)

Most of the time you can find the answer by googlling "plotly.js [your question]". Example: "plotly.js log scale"
