Again : I love OxyPlot.  Keep it going !

I am now using a plot inside a scroll viewer. Scrolling (with the scroll wheel of my mouse) through my scroll viewer while reaching my plot, interferes with the scroll zoom of the plot, mixing up my plot.

It would be nice if the scroll zoom could be disabled while keeping the zoom by rectangle enabled.

Sander.

objo wrote at 2011-08-10 13:24:

set IsZoomEnabled = false on the axes where you want the scroll wheel to be disabled. The property is only available when defining a PlotModel, I will add it to the WPF Axis controls later.

See the "Zooming disabled" example in the ExampleBrowser application (working for both WPF and Silverlight).

steunissen wrote at 2011-08-10 14:57:

IsZoomEnabled=false  disables both the zoom by scrollwheel and zoom by drawing a rectangle on the chart.

I would like to have a property like : ScrollWheelZoomEnabled=false;

objo wrote at 2011-08-24 07:34:

I added IsMouseWheelEnabled to the WPF and SL Plot controls. This will enable/disable the mouse wheel for all axes. If you need individual settings for each axis, we need to add a property to the Axis class.

Hello,

I would like to make a simple plot in a Windows Forms Application. After pressing a button the plot should be displayed. So far I have done following steps:

1. Created Windows Forms Application project,

2. Added one button that should display the plot,

3. Added OxyPlot Package by choosing Tools->Library Package Manager-> Package Manager Console and printing Install-Package OxyPlot.WindowsForms

4. I chose one Plot from the examples:

[Example("LineSeries")]

       public static PlotModel LineSeries()

       {

           var plotModel1 = new PlotModel();

           plotModel1.LegendSymbolLength = 24;

           plotModel1.Title = "LineSeries";

           plotModel1.Axes.Add();

           plotModel1.Axes.Add();

           plotModel1.Series.Add();

          var linearAxis1 = new LinearAxis();

           linearAxis1.Position = AxisPosition.Bottom;

           plotModel1.Axes.Add(linearAxis1);

           var linearAxis2 = new LinearAxis();

           plotModel1.Axes.Add(linearAxis2);

           var lineSeries1 = new LineSeries();

           lineSeries1.Color = OxyColors.SkyBlue;

           lineSeries1.MarkerFill = OxyColors.SkyBlue;

           lineSeries1.MarkerSize = 6;

           lineSeries1.MarkerStroke = OxyColors.White;

           lineSeries1.MarkerStrokeThickness = 1.5;

           lineSeries1.MarkerType = MarkerType.Circle;

           lineSeries1.Title = "Series 1";

           lineSeries1.Points.Add(new DataPoint(0,10));

           lineSeries1.Points.Add(new DataPoint(10,40));

           lineSeries1.Points.Add(new DataPoint(40,20));

           lineSeries1.Points.Add(new DataPoint(60,30));

           plotModel1.Series.Add(lineSeries1);

           return plotModel1;

       }

End there is my question. I have the code for the button like this:

  private void button1(object sender, EventArgs e)

        {

        }

How to use the code from [Example("LineSeries")] in button1?

Any help appreciated.

You need to add an OxyPlot.WindowsForms.Plot control to your Form.

Then set the Model property of that control to the model provided by your LineSeries method.

See Examples/WindowsForms/WindowsFormsDemo/Form1.cs

Hello Objo,

Thanks for the answer. In Examples\WindowsForms\WindowsFormsDemo\ I can find only these flies: OxyPlot.dll, OxyPlot.WindowsForms.dll, WindowsFormsDemo.exe and no Form1.cs

Hi!  I' ve a big problem on displaying a dataseries because in some cases not all points are being show in the graph

This is a dynamic dataseries which is refreshed every 5 second because it's done by incoming signals. The other dataseries are static. 

When i move the mouse or i try to zoom into the graph there are some points ( or segments ) which disappear and some others which appear.

Anyone could help me to solve this problem?

Thank you

Mike

I have an app where I need to trend data from a simullator as the simulator is running. I want to have a window of data and is changing as the simulator changes. I will display a fixed number of data on the plot and as the data changes the graph shifts left. It would be nice to only have to add the latest data point the graph shifts - i.e. to reduce CPU time.

Anybody got any ideas , I would like to hear them.

Thanks

Jerry
