IZones – inner-axis zones

Used to set up warning regions on trace charts. Each region is defined by a colour (use colour names or the standard HTML syntax here) and the start and end values for the region. Use ‘/’ to separate each zone, and ‘,’ to separate the parameters within each zone.

chSet 'izones' 'Yellow,3,13,4/Green,7,9,5'

The coloured bands always span the full range of the X-axis and repeat as many times as necessary for each trace on the chart.
