Internal plotting error for area plots within console templates

[StephanErb]

What did you do?

I tried to render the following area graph within a console template:

  <script>
  new PromConsole.Graph({
    node: document.querySelector("#greedy"),
    expr: "topk(5, service:mem_limit_bytes:sum)",
    min: 0,
    renderer: "area",
    yAxisFormatter: PromConsole.NumberFormatter.humanize1024,
    yHoverFormatter: PromConsole.NumberFormatter.humanize1024,
    yTitle: 'RAM',
    yUnits: 'B'
  })
  </script>

What did you expect to see?

My expression rendered as an area plot within a console template.

What did you see instead? Under which circumstances?

• if plotted as an area plot, the graph does not show any content.
• the same expression works great:
  • as a line plot within the console templates
  • as a line plot and even as area plot within the interactive graph viewer
• for every failed rendering attempt, the following log entry can be found within the browser console log:

rickshaw.min.js:1 Uncaught stacked series cannot have differing numbers of points: 43 vs 591; see Rickshaw.Series.fill()

Environment

• Prometheus version:

  0.20.0

Dupe of #586. Topk/bottomk don't work well in graphs.

This issue seems to be differeng. Plotting doesn't work even if I strip the topk and just try to plot service:mem_limit_bytes:sum as an area plot.

The error message indicates that we might be missing this code in console templates well https://github.com/prometheus/prometheus/pull/800/files?
