I tried one of the simplest possible spread sheets to try the graph feature. After unfruitful attempts to make it run with bar graphs (always got "invalid series" or after five minutes my ISP timed my Tiki out), I tried a pie chart. With that I immediately got a fatal error:
Fatal error: Call to undefined method GD_GRenderer::httpHeaders() in MYHOMEPAGE/tiki-18.6/tiki-graph_sheet.php on line 131
Attached please see the simple spread sheet I wanted to be plotted as pie chart.
