Altair® Panopticon


Numeric Needle Graph (Standard & Horizontal) Settings

These are divided into four tabs:

  • General


  1. Setting


    Needle Width

















    Specifies the width in pixels of each needle.

    NOTE: This is overridden when a column is added in the Size variable. Consequently, the width of the needles will be based on the comparison of their size in relation to where they are located on the X-axis.

    Max Focus Radius


    Determines the maximum radius of the focus circle when hovering on the needles.

    This also controls the padding of the axis in the direction in which the needles expand, allowing the focus circle to have enough space to be drawn.

    Show Border around Needles

    Specifies whether a border is drawn around needles. These are only visible if the Needle Width is greater than 1 pixel.

    Show Labels in Needles

    Specifies whether node labels will be displayed.
