Hi,
I was wondering if it is possible to stack line series, to get something like this:





I've been looking in the examples, but didn't find any similar...
Thank you

Thanks, your AreaSeries solution was exactly what I was looking for.

public IEnumerable<AreaSeries> StackLineSeries(IList<LineSeries> series)
        {
            double[] total = new double[series[0].Points.Count];

            LineSeries lineSeries;
            AreaSeries areaSeries;

            for (int s = 0; s < series.Count; s++)
            {
                lineSeries = series[s];
                areaSeries = new AreaSeries();

                for (int p = 0; p<lineSeries.Points.Count; p++)
                {
                    double x = lineSeries.Points[p].X;
                    double y = lineSeries.Points[p].Y;

                    areaSeries.Points.Add(new DataPoint(x, total[p]));
                    total[p] += y;
                    areaSeries.Points2.Add(new DataPoint(x, total[p]));
                }

                yield return areaSeries;
            }
        }

Hi obj. You have written an export demo where it is possible to export a plot model to (for instance) csv format. Can you do this also for line series? Than you can use this export routine as well for the export of plot models.

I think that an export of a line series could be interesting for developers. Having such a routine, one is able to write an export function if some clicks on the curve or on the legend to export the raw data.

Another application is to compare simulation results with measurement data. First you simulate something and plot this into a window. Afterwards you load the measurement data and plot them also to the window.

In such a situation it will be more convenient to have an import/export function for line series because the measurement data are often available in csv format.

I think this should be the responsibility of the application! But I think it requires the selection feature (http://oxyplot.codeplex.com/workitem/8193) if you want to click and export one curve only.

I see it could also be convenient to have it built-into the plot controls, so I added it as issue http://oxyplot.codeplex.com/workitem/10002!

Hi objo. Thanks for this support. Of course, I agree with you, that the application should be responsible for such a feature. On the other hand you intend to support a selection feature. I didn't know that before. 

But with this information I think that a built-in function is not necessary and yields less flexibility. Think about different possible csv formats ... Instead of a built-in function with minor flexibility an export example based on the selection feature would be sufficient. This could avoid further feature requests because everyone has than a template which can be modified for special purposes.

Hi,

Does anybody knows how to paint this kind of graphic with oxyplot?



The idea is to fill areas above of some baseline with one color and another color below baseline?

Thanks everytimer for your quick response. But how to use the AxisChanged event? This does only fire if I zoom or pan not if the values increase.

I simply added the event like so:

var timeAxis = new LinearAxis(AxisPosition.Bottom, 0) { MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Title = "Time", Unit="s" };
PlotModel.Axes.Add(timeAxis);
timeAxis.AxisChanged +=timeAxis_AxisChanged;

So there is no min/max defined and the axis increases its values as needed.

I would like to get a (oscilloscope like) behaviour like this. That the X axis is fixed to a small window of 5 seconds of the newest data, here is an example:
