            Bug ID: 158282
           Summary: Web Inspector: memory category timelines should all
                    use the same y-scale
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector

Currently, they are all independently scaled to the timeline height based on the visible data. So, if a page has 1MB of images, its scale is [0, 2] and it always renders as 50% * height. Another category could have range [0, 100MB] and 50% * height would represent 50MB. So it currently isn't possible to visually compare different category timelines. This seems like it strictly reduces the usefulness of the split out timelines.

I think they should retain the relative sizes like in the stacked line graph, which seems to be scaled to [0, max(sum(categories)]. We probably instead want the scale to be [0, max(categories)] so that the max-value category reaches 100% * height at its max value.
