so basically i am using an xls file to generate my graphs with fusion charts.. my xls file has roughly 4400 lines/set of variables to create the chart.. which shows data over a month's worth of time.. this file is being updated every hour via a cronjob , however I can't get the chart to display all the data...at around 5+ days worth of data.. the charts simply crash and show "no data to display" if i add it manually all the data shows correctly.. any suggestions?

any other suggestions... breaking up the graphs is not an option.. i need to have the 30 days on one graph
