--------------------------------
Summary: Chart with large dataset hangs and the UI becomes
irresponsive
Key: FLEX-34999
URL: https://issues.apache.org/jira/browse/FLEX-34999
Project: Apache Flex
Issue Type: Bug
Components: Charts:Interaction, Charts:Multiple Axes
Affects Versions: Adobe Flex SDK 3.4 (Release)
Reporter: Bhaskar G
Flex Version: 3.4
Component: Line chart.
Axis: Two linear Y-axis and x-axis as Date Time Axis.
Problem:
Irrespective of OS and browsers, the chart and flash stops responding while
viewing chart with 1 full week of data that contains 6-10 line series for each
property to view the trend, each line series have 10080 points(Since it is date
time axis chart each minute have a data point and this is the maximum number of
data samples for full week range).
Workaround we tried:
1. *Tried not to load all the line series in the chart at the initial load*.
Instead enable/toggle one series at a timer using timer set to 10 seconds. The
UI is responsive till 2-3 series enabled with full week of data points, after
that the chart will start to respond slowly and when it comes to all the line
series in the chart toggled on, the UI stops responding and sometime flash
player crashes.
2. Break the large data set into two equal halves. Loaded the first half of the
data in the chart and now chart is responding. But after that while loading the
second half of the data to each line series using a timer set to 10 seconds the
UI stops responding and again we see the same issue as we had with scenario 1.
3. Toggle off all the properties in the initial load and limited the user to
enable a maximum of 2-3 line series at a time to view in the chart.
4. Suggested day mode in Chart, where in the chart is loaded with only single
day's data points. Each line series will have 1440(Maximum number of sample per
day for single property). In this scenario the chart is working as usual and we
don't have performance issue.
