Hi,

In my application, I need to ensure that the actual plot area where the chart is drawn in always square.

Please advice - sample code welcome.

Thanks,

Warm Regards,

- Vikram

I think you can change the "PlotMargins" of the plot each time the size of the plot changes...

Or make sure the size of the control is square (handle the sizechanged event on the control or override the coerce value callbacks on the width/height dependency properties?).

Thanks for your reply.

I understand that I need to adjust plot margins in resize event of the control. I am not clear about the calculation. I have adjusted margins using height / width of the control, and height / width of the title area. This still does not make the plot area square. Here is my calculation:

        private void AdjustPoincareChartMargins(Plot plot, double dWidth, double dHeight)
        {
            Debug.WriteLine("Available W: " + dWidth + ", H: " + dHeight);

            plot.Model.IsLegendVisible = false;
            var availableWidth = dWidth;
            var availableHeight = dHeight - plot.Model.TitleArea.Height;

            var horzMargin = Math.Max(0, (availableWidth - availableHeight)) / 2;
            var vertMargin = Math.Max(0, (availableHeight - availableWidth)) / 2;

            plot.Model.PlotMargins = new OxyPlot.OxyThickness(horzMargin, vertMargin, horzMargin, vertMargin);

            Debug.WriteLine("Plot W: " + plot.Model.PlotArea.Width + ", H: " + plot.Model.PlotArea.Height);
            Debug.WriteLine("PlotAndAxisArea W: " + plot.Model.PlotAndAxisArea.Width + ", H: " + plot.Model.PlotAndAxisArea.Height);
        }

Thanks,
- Vikram

• ...to overlay different ploting series in one ploting area?
• ...to add annotations to each datapoint?
• ...to position these annotations outside of the ploting area?

The result shoud be something like this:

Yes, you can overlay any number of plotting series in the same plot - it should not be any problem to combine line, scatter points and columns (bar) series as in your example.

You can create a string for each data point that will be shown when you use the mouse tracker, but currently only the BarSeries has the ability to render labels (will add this to the other series later).

You can create your own custom annotatiosn that renders in screen coordinates, anywhere in the control area.

You could also create a custom x-axis to render the club names. Simply override the Render method.

I have now an OxyPlot version of my plot: 

Using the Oxyplot library without changes of source code. 
Thank You for support, Franz
