Build 3609 fixes it. Thanks!

Hi, I'm using build 3597. When the legend box is inside the plot area (cfx:Chart.TargetPanel="Inside"), and I use a GridSplitter to shrink the chart down to nothing, I get the following error: Width and Height must be non-negative. at System.Windows.Rect..ctor(Double x, Double y, Double width, Double height) at ChartFX.WPF.Internal.PlotAreaCore.b(Size A_0, UIElementCollection A_1) at

Just run the app, then use the GridSplitter (it's right above the chart) and drag it all the way to the bottom of the window, as far as it will go. This should produce the error. I've also noticed that if the chart has hardcoded SeriesAttributes, and the legend box is inside the plot area, the legend box won't show up. In the test app, uncomment the 2 SeriesAttributes lines in Window2.xaml, then in Window2.xaml.vb:ReinitializeData(), get rid of the 2 lines that set the chart's ItemSource. Thanks.

3594 fixes it - thanks!

I'm using build 3581, experiencing an issue where if you reload the fields for the dataview, then hide the dataview, then change the data in the chart, it will crash with the following exception: "Object reference not set to an instance of an object." at ChartFX.WPF.DataGridItems.MeasureOverride(Size constraint) at System.Windows.FrameworkElement.MeasureCore(Size availableSize) at System.Windows.UIElement.Measure(Size availableSize) at System.Windows.ContextLayoutManager.UpdateLayout() at System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg) at System.Windows.Media.MediaContext.FireInvokeOnRenderCallbacks() at System.Windows.Media.MediaContext.RenderMessageHandlerCore(Object resizedCompositionTarget) at System.Windows.Media.MediaContext.RenderMessageHandler(Object resizedCompositionTarget) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) at System.Windows.Threading.DispatcherOperation.InvokeImpl() at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Windows.Threading.DispatcherOperation.Invoke() at System.Windows.Threading.Dispatcher.ProcessQueue() at System.Windows.Threading.Dispatcher.WndProcHook(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) at System.Windows.Threading.Dispatcher.InvokeImpl(DispatcherPriority priority, TimeSpan timeout, Delegate method, Object args, Boolean isSingleParameter) at MS.Win32.HwndSubclass.SubclassWndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam) at MS.Win32.UnsafeNativeMethods.DispatchMessage(MSG& msg) at System.Windows.Threading.Dispatcher.TranslateAndDispatchMessage(MSG& msg) at System.Windows.Threading.Dispatcher.PushFrameImpl(DispatcherFrame frame) at System.Windows.Application.RunInternal(Window window) at ChartFXWPFTest.Application.Main() in C:\dev\ChartFXWPFTest14\ChartFXWPFTest\obj\Debug\Application.g.vb:line 62 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() I've attached an app that reproduces this.

I'm using build 3554, and I'm having a problem removing fields from the data view. If I call, for instance, chtTest.DataView.Fields.Items.RemoveAt(0) in the DataBound event of the chart after calling chtTest.DataView.Fields.ReloadFieldsFromData(), the data view stops working and I get the following error written to output: System.Windows.Data Error: 16 : Cannot get 'Data' value (type 'IEnumerable') from '' (type 'ItemsSourceHolder').

This is a follow-up to this thread: http://community.softwarefx.com/forums/t/10389.aspx We've been having issues with axis templates for a while now. Many of these are still occurring in build 3547. The main issue we're having right now is that if you resize the chart, the axis labels will either disappear or flicker. See the last post in the above thread for more details and an example app. Also, when a UserControl contains a chart and that UserControl is moved in code from one ContentPresenter to another, the following crash occurs: System.InvalidOperationException: Specified element is already the logical child of another element. Disconnect it first. at System.Windows.FrameworkElement.ChangeLogicalParent(DependencyObject newParent) at MS.Internal.FrameworkObject.ChangeLogicalParent(DependencyObject newParent) at System.Windows.FrameworkElement.AddLogicalChild(Object child) at System.Windows.Controls.UIElementCollection.SetLogicalParent(UIElement element) at System.Windows.Controls.UIElementCollection.AddInternal(UIElement element) at System.Windows.Controls.UIElementCollection.Add(UIElement element) at ChartFX.WPF.Internal.MyItemsControlCanvas.a(IEnumerable A_0) at ChartFX.WPF.Axis.AxisCategoricalItems.c(Size A_0) at System.Windows.FrameworkElement.ArrangeCore(Rect finalRect) at System.Windows.UIElement.Arrange(Rect finalRect) at ChartFX.WPF.Controls.AxisPanel.ArrangeOverride(Size finalSize) at System.Windows.FrameworkElement.ArrangeCore(Rect finalRect) at System.Windows.UIElement.Arrange(Rect finalRect) at ChartFX.WPF.Controls.SpacingDockPanel.ArrangeOverride(Size finalSize) at System.Windows.FrameworkElement.ArrangeCore(Rect finalRect) at System.Windows.UIElement.Arrange(Rect finalRect) at System.Windows.Controls.Border.ArrangeOverride(Size finalSize) at System.Windows.FrameworkElement.ArrangeCore(Rect finalRect) at System.Windows.UIElement.Arrange(Rect finalRect) at System.Windows.Controls.Border.ArrangeOverride(Size finalSize) at System.Windows.FrameworkElement.ArrangeCore(Rect finalRect) at System.Windows.UIElement.Arrange(Rect finalRect) at System.Windows.Controls.Control.ArrangeOverride(Size arrangeBounds) at System.Windows.FrameworkElement.ArrangeCore(Rect finalRect) at System.Windows.UIElement.Arrange(Rect finalRect) at System.Windows.ContextLayoutManager.UpdateLayout() at System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg) at System.Windows.Media.MediaContext.InvokeOnRenderCallback.DoWork() at System.Windows.Media.MediaContext.FireInvokeOnRenderCallbacks() at System.Windows.Media.MediaContext.RenderMessageHandlerCore(Object resizedCompositionTarget) at System.Windows.Media.MediaContext.RenderMessageHandler(Object resizedCompositionTarget) at System.Windows.Media.MediaContext.Resize(ICompositionTarget resizedCompositionTarget) at System.Windows.Interop.HwndTarget.OnResize() at System.Windows.Interop.HwndTarget.HandleMessage(Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Interop.HwndSource.HwndTargetFilterMessage(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) It works fine if there is no custom axis label. Unfortunately I can't seem to reproduce it in a sample app, it seems to be something specific to our application. As I said, this problem doesn't seem to occur anywhere else though. Are there any plans to fix the issues with custom axis labels, or can you give me any suggestions on how to get around this? Thank you.

It seems to be fixed in build 3544. Thanks!

I'm using build 3538. The initial issue I was having with generating series (http://community.softwarefx.com/forums/t/10694.aspx) has been fixed, but there are a couple of new issues: 1. If you hide the legend item for a series and then refresh the data, it crashes. 2. If you refresh the data more than once, the legend will stop highlighting series on mouse-over. I've attached an app that reproduces this. To reproduce issue 1, click "Reload Data", then "Hide Series", then "Reload Data" again - it will crash. To reproduce issue 2, click "Reload Data" twice, and the legend will stop responding to mouse-over. Thanks.

There are some problems in the latest build (3533) when setting the ItemsSource. I've attached an app that reproduces them. 1. If you click the "Reload Data 1" button (1 series), then click "Reload Data 2" (2 series) it will crash. 2. If you uncomment the line in the New() constructor that says "chtTest.ItemsSource = Nothing", the legend box for the charts will not be generated at all. Please let me know if you need any more information. Thanks.

Some of these issues have been fixed in recent builds, however there is an issue where if you resize the chart horizontally the labels disappear and there is a lot of flicker in the labels when resizing vertically. This happens in build 3532. I've attached an app that reproduces this. Thanks.

We're having an issue with build 3515.22977 where stacked bar charts will sometimes crash. It seems to happen if some of the series are set to stacked, and other aren't.

Thanks.

Build 3511 does appear to fix this issue. It also seems to fix the issues we were having with changing data bindings and using axis label templates. Thanks!

I've attached an app that reproduces this issue. If you open it, then click on "Stacked", then "Unstacked", then "Stacked" again, it should produce that error.

Using build 3499. There's a crash that happens when the following steps are performed: 1. Set a bar chart's ItemsSource to something, and set its AllSeries.StackedStyle to "No". 2. Set the chart's ItemsSource to something different, which has more points than the previous ItemsSource, and set the AllSeries.StackedStyle to "Normal".

Attached is an app that reproduces the issue. The first time you click the "Test" button (which reloads the data), it will load fine. However, if you click it again the error will occur.

Attached is a test app which reproduces the issue. Note that there now seems to be 2 separate issues - the first time you load the data (by clicking the button at the bottom) there is the issue with the labels not being hidden (you may have to scroll slowly to reproduce this). If you reload the data again, another issue happens where the labels will be too far to the right and will overlap the scrollbar. Please let me know if you need any more info - thanks again.

I forgot to mention - it looks like almost the exact same issue here: http://www.softwarefx.co.kr/Forums/ShowPost.aspx?PostID=1688 (ran this through Google Translate).

Please let me know if you'd like me to send it. I'm assuming the address is still wpf@softwarefx.com ? Thanks.

I'm using build 3499. There seems to still be an issue with axis data templates where it sometimes doesn't hide the label when the label's point is outside the scroll viewer's visible area. This seems to happen most when scrolling slowly so I suspect it's showing labels if the point is even partially in the visible area (even though the scroll behaviour is to either completely show a point or not show it at all). I'm using the following template: <cfx:Axis.Template> <DataTemplate> <TextBlock Text="{Binding Text}" /> </DataTemplate> </cfx:Axis.Template> Any ideas? Thanks.

It looks like build 3460 does fix the binding issue even without KeepVisualsOnUnload, so I've left it unset. Thanks again!

Tested with build 3460, it now works properly when the KeepVisualsOnUnload property is set. Thanks!

Test app sent - let me know if you need any more information. Thanks again.

There seems to be a bug when using binding on the chart's ItemsSource property. Steps to reproduce: 1. Create a UserControl that contains a chart. Bind the ItemsSource property of the chart to an ObservableCollection property in the code-behind of the UserControl. 2. Have a button on the UserControl that clears the ObservableCollection and adds new data (i.e. to change the data in the chart) 3. Everything works fine at this point - the button refreshes the chart as it should. Now, in some sort of event (e.g. on a Button Click event on the original window), detach the UserControl from its original container (grid, panel, etc) and attach it to a ContentPresenter in another window, then display the other window. The current data on the chart will display fine, but clicking the button no longer refreshes the chart. I'm pretty sure this is a ChartFX issue, since if I have a combo box on the UserControl which uses exactly the same binding, there is no problem. I have a test app that reproduces this issue, please let me know if you want me to send it. Thank you.

That code worked - thanks!

This seems to be fixed in build 3442 - thanks!
