showing Y axis from zero

[Krispie78]

Hi Guys, I'm looking for a solution to have the Y axis always starting from zero instead of zooming in and showing only fe. from 5 to 8 on the y axis. The rest of the windows should still zoom in automaticaly as it is now. I would just really want to always see the full Y-axis, fe. from 0 to 8 (if 8 would be the maximum value in the graph). Any suggestions would be apreciated !

Current configuration:

type: custom:plotly-graph
time_offset: $fn () => (900000-(Date.now() % 900000 - 3340)).toFixed(0) + 'ms'
defaults:
  entity:
    show_value: true
entities:
  - entity: binary_sensor.capacity_warning
    line:
      color: lightgray
      width: 1

Fix yaxis range:

layout:
  yaxis:
    range: [0, 8]

Other suggestions:

time_offset: $ex (900000-(Date.now() % 900000 - 3340)).toFixed(0) + 'ms'
refresh_interval: auto
hours_to_show: 15m

Hi, thanks for your feedback. I changed all as suggested. Only thing I didn't implement is 'hours_to_show: 15m', as I want to show 15m but have to compensate for the time_offset. Please find adapted version below.

Problem is : setting the range doesn't seem to change anything. The Y axis is still not starting from zero (unless for periods where there are verry low values in the graphics). Next to that: the maximum of '8' is a problem as, the to of the Y ax would still need to be automatic..

I don't think plotly can be configured to set the minimum of a range but leave the max floating.
One Trick you could do is to add a second trace that shared the yaxis and has one datum with a y value of 0. Then you can make it transparent and hide the legend.

Hi, that would indeed be a good work around. Thanks !

[dbuezas]

Good luck!
Look into filters, particularly store_var and map_y

@Krispie78 Did you find a workaround you could share please?

I'm not certain of this yet, but null seems to work as a maximum to keep a range dynamic? I seem to have had some success configuring it so far anyway. Whether it will stop working as the data changes, only time will tell.

  yaxis:
    range:
      - -5
      - null

There's a better way now

layout:
  yaxis:
    autorangeoptions:
      minallowed: 35
