mhowes Posted September 10, 2007 Report Share Posted September 10, 2007 I have a simple line chart on a tab control. Data is loaded into the chart before the user chooses that tab. When I click on that tab it takes the chart 5-6 seconds to display. Huh???? Data is bound to the chart using an ArrayList which contains Arrays, one array for each set of X values and one array for the Y values. I have 10 X/Y pairs all together with about 2500 points in each. This is just test data. The datasets will have around 20,000 data points. But I'm not convinced its the data. Once the chart has finally painted after i've clicked on the tab. I click to another tab and then immediatly click the tab with ChartFx on it. The data is NOT reloaded when this happens but it still takes 5-6 seconds for the chart to paint. I've changed almost none of default properties. any ideas what's going on? thanks mike Quote Link to comment Share on other sites More sharing options...
