SDK 4.9.1 chart optimization was on style initialization, which was done for every chart , while it was required only once per module. So the performance gain is only when you have many charts.
You say that your test has one chart, and it takes 8 seconds to initialize the axis. - Can you run the performance profiler on that part and see what is taking that 8 sec ? - your example is missing the data that is used in the chart. Can you please take the time to build a fully operational test case that show the issue, and post the source code here, so that we can help you more efficiently.

Moving to anything above 4.6 is impossible without severe development from our end. Our primary limiting factor is we use the IBM ILOG Elixir Gantt Chart component and it is critical to our application. This was not originally owned by IBM and was well supported in the early days. Nowadays following the buy out, development and support is virtually none existant. The last working version of Flex SDK that is compatible is 4.6, anything above that results in the following error: ReferenceError: Error #1065: Variable com.ibm.ilog.elixir.utils::LicenseHandler is not defined. As a result we need to write our own component to replace this one but that will require significant man days of effort or get them to support later SDK version which will also result in a long wait (if it ever happens)! So....... Maurice/Alex, I have downloaded the 4.9.1 SDK and reconfigured the application to use it. Ignoring the fact the gantt control based functionality breaks, I can test the chart functionality as it's in a completely different area. *With the 4.9.1 SDK the chart is still as slow initialising, so that change does not help after all*. I have a chart defined thus (it's only partially based on the real one but what I'm testing against at the moment): <mx:LineChart id="requiredVsActualLineChart" dataProvider="{requiredVsActualDataProvider}" showDataTips="true" dataTipFunction="requiredVsActualDataTipFunction" height="210" width="100%" paddingTop="4" paddingRight="20"> <mx:horizontalAxis> <mx:CategoryAxis id="requiredVsActualCategoryAxis" categoryField="On"/> </mx:horizontalAxis> </mx:LineChart> Now if after the chart has shown I run the following code to set up the vertical axis, it takes 8 seconds!!!! var linearAxis:LinearAxis = new LinearAxis(); linearAxis.interval = 0.1; linearAxis.baseAtZero = true; linearAxis.maximum = 100; linearAxis.minimum = 0; requiredVsActualLineChart.verticalAxis = linearAxis; So what is up with that?! -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Patching-Flex-4-6-SDK-chart-functionality-tp5527p5597.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
