Add UMA metrics per NTP icon types, broken down per position |
||
Issue descriptionWe'd like to understand if the distribution of the types correlate with the order presented on the NTP. For example, is more common that REAL are shown before COLORED which is shown before GRAY?

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/8619a463c1a4ec861c542c9482c502a6df96acdf commit 8619a463c1a4ec861c542c9482c502a6df96acdf Author: mastiz <mastiz@chromium.org> Date: Thu Feb 09 16:46:13 2017 ntp_tiles: Add UMA histograms to correlate icon type to position The previously instrumented UMA histograms measure the number of tiles per icon type, but not their position. We suspect there could be a correlation between the position and the type, so new histograms are proposed to verify this.
