Currently, data correction settings for the download charts are only accessible from the charts themselves:

• chart modal (open from the button adjacent to the sparkline chart in the package page)
• compare page

After some time, users might forget they had them modified, and might be surprised to see some differences in intermediary download values, compared to other sources (see #2510 ) . The smoothing algorithm preserves the first and last values, but smoothens intermediate values). In this case, remembering where the inputs are located could become a challenge.

Proposed solution:

• add a 'data correction' section in the settings page, and show a reset button, enabled if any correction was applied. It should reset default parameters to:

  chartFilter: {
    averageWindow: 0,
    smoothingTau: 0,
    anomaliesFixed: true,
    predictionPoints: 4,
  }

• optional: add an explanation on where the data correction parameters are located, with a link to the downloads modal route.
