Settings Menu

1. Click on the Setting gear icon to draw out the Setting menu


The Save option allows the users to save the chart with the current configurations. This will allow them to reopen them as they were saved.


  • The user would enter the name of the chart to be saved in the top field.

  • Under Folder Path, the user can either select nothing, or select any existing Folder Paths that might have been created, or create a new custom Folder Path. A folder path is a way for the user to organize and categorize the charts. All the charts in a folder path will be nested together in a folder.

    • Selecting nothing will display the chart and not nest it under a folder.

    • Selecting an existing folder path will nest the current chart into that selected folder.

    • To create a new Folder Path, toggle to Custom and enter a name. Next time a new chart is created, the newly created folder path will appear as an option to save the new chart under.

Example of existing Folder Paths:

Example of how Folder Paths appear in the app. They will have a grid icon on the left, the name and an arrow of the right side indicating nested charts.

Inside the Folder Path, you’ll find the available nested chart(s).

Series Options

The Series Settings menu allows to customize trends to the user’s preference.


Choose a suitable interval for the charts to rollup the data. Rollups are inclusive of start and exclusive of end times. For example a daily rollup includes midnight of the current day, but excludes midnight of the next day. All the items found within the interval are passed to the folding function to compute a timestamp/val pair with each timestamp aligned to the start of the interval.

For example a rollup interval of 1day over a one year range would calculate 365 (or 366 if leap year) items with the start time being midnight of each day. Interval rules:

  • Less 1day: use absolute time, aligned off start (example 1hr)

  • 1day: daily rollup, aligned off midnight

  • 1wk: weekly rollup, aligned off midnight on Sunday

  • 1mo: monthly rollup, aligned off midnight on 1st of month

  • 3mo: quarterly rollup, aligned off midnight on 1st of 3 month intervals

  • 1yr: yearly rollup, aligned off midnight Jan 1st


Change the color either by hex-code or selecting from the palette.
