问题 I'm asynchonrously getting data and attempting to populate a plot via the LineSeries, except the plot does not refresh when the bound collection (ObservableCollection) is updated. Note: I have a XAML behavior to call InvalidatePlot(true) when the bound collection changes. Can anyone explain why the plot is not updating as expected? WPF .Net 4.0 OxyPlot 2014.1.293.1 I have the following XAML datatemplate, as you can see the LineSeries ItemsSource is bound to a property (PlotData) in the

My project is in WPF format so I was originally using a hosted WINFORMS chart and that worked like a charm and did absolutely everything I needed it to until I needed to overlay a WPF element on top of the hosted winform chart. Due to the "AirSpace" issue, I was not able to see the WPF element that I put on top of the hosted chart no matter what I did. That is when I

问题 I'm new to wpf and oxyPlot. Now, I want create a dynamic line chart like an oscilloscope, but I don't know how to lock the axis on a value when mouse wheel zooms. Example: The red point is mouse location. In normal, zoom A -> B, zoom C -> D. now, I want to zoom C ->E, like mouse location at 0 center. 回答1: I've found a solution that works for blocking an axis zoom center.

问题 I'm trying to graph a trend line for my data. Is there anyway to define a custom function?
