User (Legacy) Posted May 8, 1999 Report Share Posted May 8, 1999 I have been creating some line XY graphs showing how a particular measurement varies over time and have had problems when trying to handle multiple series with different numbers of points. The method I tried was: a) Determine series with maximum number of points and initialise the chart with that number of points. For each series plot the actual points and then set all remaining points (i.e. up to maximum number specified for chart) to XValue = 0 YValue = CHART_HIDDEN This crashed the web server completely - it seems that hidden points are a no-no in XY graphs. To get round this I ended up setting unused points in each series to the same value as the last real point. This seems to work but setting unused points to hidden would be clearer.
