Chart Component Identification

Discrete chart components can be assigned GINO segment identifiers using the following routine:

where offset is the segment number offset used when drawing the chart component. Thus when a histogram, bar chart, step chart, area chart or pie chart is drawn, each component is placed, in order, within a GINO segment of identifier 'component' + offset. Users are referred  to the Section on Picture Segments in the GINO User Manual for further information on the use of segments.

Setting offset to -1 will switch off the identification process, which is the default state when GINOGRAF is initialised.

The current segment offset setting can be enquired using the following integer function:

This feature does not operate on multi data set, polar, vector or text charts.
