Hello, I ran into a problem - with a small window size, the graphics tracker goes beyond it. The problem is visible on the attached image. Maybe there are some ways to display the tracker in a certain position, regardless of the point being watched (the most preferred option), or can this problem be solved in other ways? Thank.

  • What position do you want to put the tracker in? - Ev_Hyper
  • Why not just forbid minimizing to such a size? - Ev_Hyper
  • @Ev_Hyper can be placed somewhere right below, closer to the contour of the window. - SNMetamorph

You can set the appearance and location of the tracker by overriding the DefaultTrackerTemplate .

A simple sketch - the direction in which direction to look:

 <oxy:Plot Title=""> <oxy:Plot.DefaultTrackerTemplate> <ControlTemplate> <Canvas> <TextBlock Canvas.Left="0" Canvas.Top="0" Margin="10" Background="LightYellow" Padding="5" Text="{Binding}" /> </Canvas> </ControlTemplate> </oxy:Plot.DefaultTrackerTemplate>

The result will be as follows

The TrackerFormatString property is responsible for the way the data is TrackerFormatString . They are different for each series; you can also find out which parameter you are responsible for in the documentation.

For example for LineSeries :

 {0} - заголовок текущей серии {1} - название оси X {2} - значение X {3} - название оси Y {4} - значение Y

Specific example

 <oxy:LineSeries Title="Sin (x)" ItemsSource="{Binding Points}" TrackerFormatString="X = {2:00}, Y = {4:00}" Color="Red" />

Also examples of customization of the tracker template can be viewed in the examples for the project on GitHub.

More information about the capabilities of the tracker can be found in the documentation.

  • I thank, dealt with the position. Now I’m trying to insert a string with time in TrackerFormatString, but for some reason it isn’t dynamically updated - SNMetamorph
  • @SNMetamorph write a little more details, you need at least a few test values - Ev_Hyper
  • In the picture , in the tracker, after the letter T, the X coordinate of the point is displayed, in my code this is done - the coordinate of each subsequent point is 1 greater than the previous one, that is, the very first point on the graph has a coordinate of 0, the second is 1, and so on. But instead of these coordinates I want to display in the tracker the time of appearance of each point on the chart, I tried to edit TrackerFormatString - it does not work out, apparently it can only be used with arguments provided by the library. It should look like this: T: 19:42 S: some number - SNMetamorph
  • @SNMetamorph then you need to save the acquisition time either in the model, or only save the starting time and already map the result with its account. But the first option is simpler and in this case it seems more logical - Ev_Hyper
