Re: ColorLine bug

I think that for now I can perhaps get away with just using a CursorTool, which can render the same effect yet stay within bounds.

Thanks.

Re: Exception w/ DoubleClick on SubChart

Since I don't need to handle double click events from my chart, for the time being it looks like I can work around the exception with a global exception handler. public App() { DispatcherUnhandledException += ApplicationOnDispatcherUnhandledException; } private void ApplicationOnDispatcherUnhandledE...

Re: Exception w/ DoubleClick on SubChart

Thanks, Sandra.

Is there any work around you can suggest? If not, is there any way we can get a hot fix?

This is a critical issue which will prevent the shipping of our application and affect product demos.

Thanks for the attention.

ColorLine bug

ColorLineBug.png My WPF TeeChart has multiple ColorLines attached to the Bottom axis. Unfortunately, the lines that have values outside of the "series area" of my chart are still being drawn. In the image above, you can see the ColorLines drawing over my axis label area. I'm adding the lines with c...

Exception w/ DoubleClick on SubChart

It seems that TeeChart.WPF throws an exception when double clicking on a subchart (well, at least in my example). I have sample code I can provide, however I would rather not attach it to this post. Is there somewhere else I can send it? Any solution or work around would be much appreciated, as this...

Axis labels in series area?

Graph example.png In developing my own custom implementation of a ScrollPager-type widget, I'd like to display the labels for my bottom axis within the area where my series are graphed, as illustrated in the image above. Is this possible with TeeChart? Is there a way to create such an effect using ...

Re: Simulate ScrollPager on Android?

I got this working with mouse events and a ColorBand on WPF, which should port over to touch events and ColorBand on Android. Thanks!

Re: Simulate ScrollPager on Android?

The Android version lacks the GanttTool, and thus it doesn't seem that there is any way to drag the Gantt rectangle. The RectangleTool is also missing, so that doesn't appear to be a viable option. The ColorBand tool is present, however I don't immediately see a way to make it draggable. (I'm also h...

Simulate ScrollPager on Android?

Since it appears that TeeChart for Xamarin.Android doesn't support scroll pager, I'm wondering if there is any way to simulate it? Perhaps using a transparent, movable Gantt that overlays my "overview" series and update the min/max of the "detail" series based upon the Gantt position? Any other idea...

Re: Gantt series performance

Thanks, Sandra! You've saved the day.

Memory usage is now a slim 50MB for 10,000 items.

Re: Gantt series performance

Thanks! This has improved execution time tremendously. However, the memory usage by the Gantt series is huge. With more than around 12000 items, I get an out-of-memory exception. Memory usage in my sample app is around 850MB with 10000 items. Is there anything that can be done to reduce memory usage...

Gantt series performance

I have a Gantt series that will ultimately need to display thousands of bars. With only ~600 bars, drawing is taking upwards of 15 seconds. I just need the Gantt to display simple, plain boxes such as those in the attached image. However, when my entire data set is loaded there will be many thousand...

Re: Resize Gantt item programically?

Thanks, so I gather that to resize an item I need to delete it and then add a new item of appropriate size.

It seems I may have a more fundamental problem with performance, though (see post to follow).
