over writing output image -- not appending timestep number

[nicolemarsaglia]

Having a scene declaration like this and each timestep is writing to this file path. We should append the timestep by default.

-
  action: "add_scenes"
  scenes:
    s1:
      plots:
        p1:
          type: "pseudocolor"
          field: "pressure"
          pipeline: "pl1"
        p2:
          type: "pseudocolor"
          field: "log_density"
          pipeline: "pl2"
      image_name: "marbl_3D_logdensity_over_pressure"

current result when running with a simulation: a single image named marbl_3D_logdensity_over_pressure.png

Does image_prefix help instead of image_name ?

You could also try:
marbl_3D_logdensity_over_pressure_{cycle:06d}.png

[nicolemarsaglia]

image_prefix works! do we want this to be the behavior of image_name? I feel like we should assume they don't want just one image and don't realize the difference until it's too late, like me.

[cyrush]

image_prefix and image_name were to be distinct, and the image_name was for when you know exactly you want. Maybe we should document this better?

[nicolemarsaglia]

Definitely.
