I use OxyPlot Control In silverlight ChildWindow, when I click left mouse ,to show clicked Point value, but the control show value not on my mouse arrow.it's location offset a lot. How is it?How to solve this problem?Thanks !!!

objo wrote at 2012-03-20 18:40:

Can you try to replace the OxyPlot control with a Canvas, and check the mouse locations reported there - to rule out if the problem is with your panel/container.

Hello!

I would like to know how can I export details of the plotmodel (like axis collection, lineseries collection with its configuration like color gridlines etc and the data/datapoint collection)  to a xml file.

I tried using xml serialization but since plotmodel uses generics and dictionaries thus unable to do so.

Could you please help ?

 Thanks!

Meenakshi

objo wrote at 2012-11-06 19:44:

I think this should be covered by http://oxyplot.codeplex.com/workitem/9986

But I don't recommend serializing the PlotModel directly - I will not guarantee backwards compatibility in the future...

brantheman wrote at 2012-06-05 19:37:

I'm trying to track down a zoom issue. Steps to repeat the issue:

1. Open the OxyPlot.Wpf solution.

2. Set the WpfExamples project as the startup project.

3. Modify WpfExamples.Examples.BarSeriesDemo.MainWindow.xaml.cs to look like this:

tmp.Axes.Add(new CategoryAxis { ItemsSource = Items, LabelField = "Label", AbsoluteMinimum = 0, AbsoluteMaximum = Items.Count, IsPanEnabled = true, IsZoomEnabled = true});tmp.Axes.Add(new LinearAxis(AxisPosition.Left) { MinimumPadding = 0, AbsoluteMinimum = 0, IsZoomEnabled = false, IsPanEnabled = false});

4. Fire up the BarSeries demo and zoom in and out. Give that mouse wheel a good strong spin and watch as you zoom to outer space, which wasn't expected given the axes' parameters noted above.

It's almost like the flip of a switch. I can even get it into a situation where a single click on the mouse wheel jumps the zoom/pan out of any viewable content.

objo wrote at 2012-06-19 12:41:

thanks for the bug report - will look into this later!

objo wrote at 2012-06-27 15:52:

I could not reproduce this. It works fine here.

I changed AbsoluteMinimum=-0.5 and AbsoluteMaximum=Items.Count-0.5 in order to get the CategoryAxis to look right (the AbsoluteMinimum/Maximum are not checked before the user tries to zoom/pan).

My code currently looks like this:

            tmp.Axes.Add(new CategoryAxis
            {
                ItemsSource = this.Items,
                LabelField = "Label",
                AbsoluteMinimum = -0.5,
                AbsoluteMaximum = this.Items.Count - 0.5,
                IsPanEnabled = true,
                IsZoomEnabled = true
            });

            tmp.Axes.Add(new LinearAxis(AxisPosition.Left)
                {
                    MinimumPadding = 0,
                    AbsoluteMinimum = 0,
                    IsZoomEnabled = false,
                    IsPanEnabled = false
                });

brantheman wrote at 2012-06-27 22:09:

This bug definitely still exists. I'm using a Microsoft mouse with a fairly recent version of Intellipoint. Normal mouse wheel behavior doesn't show the problem. You have to spin the wheel really fast for the problem to occur.

objo wrote at 2012-06-28 06:31:

Ok, I submitted a change that might help - can you verify? I still could not zoom fast enough to reproduce this error (I have an old Logitech G3 mouse with standard Windows 7 HID driver).

If it is still a problem, can you create a log of the Delta values from the MouseWheelEventArgs?

brantheman wrote at 2012-06-29 17:25:

Yes, that change fixes it. Thank you! As a second note, it appears that you're not setting the Handled property on the various mouse events for WPF when you use the event. Nor do you check it before using the event. Do you think that might help?

For the record, I did make a log of my delta values:

-120, -120, -240, -360, -360, -131, -131, -394, -262, -171, -514, -514, -514, -514, 120, 600, 600, 360, 240, -120, -240, -360, -120, -120, -131, -394, -394, -394, -394, -262, -171, -514, -514, -514, 120, 600, 240, 144, 722, 722, 433, 433, -120, -360, -360, -360, -360, -480, -131, -394, -394, -525, -171, -514, -686, -514, -686, -514, -686, -514, -202, -606, -809, -606, -809, -606, -606, -227, -908, -681, -908, -681, -247, -743, -1983, -1487, -991, -1487, -991, -743, -265, -797, -1063, -797, -797, -281, -844, -1126, -844, -2253, -844, -1126, -844, -1126, -295, -887, -1182, -887, -1182, -887, -308, -616, -925, -925, -2466, -925, -925, -319, -1279, -959, -1279, -959, -1279, -959, -330, -991, -2644, -991, -2644, -991, -1322, -340, -1361, -1020, -2722, -2041, -1361, -1020, -1361, -1020, -349, -2096, -4193, -2096, -2096, -1397, -1048, -1397, -357, -2863, -2147, -2863, -2147, -1431, -2147, -1073, -365, -1097, -2927, -5122, -2195, -1463, -1097, -1463, -373, -2240, -5227, -2240, -2987, -1120, -1120, -380, -1141, -3044, -2283, -3044, -2283, -3044, -1141, -1522, -1141, -387, -1162, -3098, -6972, -2324, -1549, -1162, -1549, -1162, -393, -1181, -1181, -1575, 120, 1440, 1200, 2160, 600, 1440, 600, 600, 288, 1733, 1444, 866, 722, 866, 188, 1132, 1887, 2265, 943, 222, 1335, 1112, 1335, 2225, 1335, 1112, 249, 1249, 1249, 2498, 1249, 272, 1636, 1363, 1636, 1363, -240, -1320, -360, -480, -360, -480, -131, -394, -1050, -788, -1050, -394, -525, -394, -394, -171, -686, -514, -1372, -1029, -686, -514, -686, -202, -606, -1213, -1618, -1213, -809, -606, -809, -606, -227, -681, -1816, -1362, -1816, -1362, -681, -908, -681, 120, 1200, 1440, 600, 720, 360, 144, 866, 722, 1733, 722, 722, 377, 1887, 1132, 943, 222, 1112, 2670, 1112, 1335, 1112, 1112, 249, 2997, 2498, 1498, 1249, 272, 1363, 3272, 2727, 1363, 1636, 1363, 584, 2924, 3509, 1462, 1462, -120, -720, -480, -360, 120, 720, 1200, 1440, 600, 720, -120, -960, -720, -480, -360, 120, 1440, 1200, 720, 600, -240, -960, -720, -480, -360, -480, -262, -525, -788, -1050, -788, -525, -394, -525, -171, -1029, -686, -514, -686, -202, -809, -1213, -1618, -606, -809, -606, -809, -227, -1816, -1362, -1816, -1362, -908, -1362, -681, -247, -991, -1487, -1983, -1487, -1983, -743, -991, -743, -265, -797, -3722, -1063, -1595, -1063, -797, -563, -3942, -1689, -1126, -1689, -844, -295, -1774, -2365, -2661, -2365, -887, -1182, -887, -308, -2466, -4316, -925, -2466, -925, -319, -1919, -1279, -1919, -1919, -1279, -959, -1279, -330, -1983, -5618, -2644, -991, -1322, -991, -1322, -340, -2041, -2722, -2041, -2722, -3062, -1020, -349, -2096, -4193, -2096, -1397, -1048, -2445, -357, -2147, -2863, -2147, -2863, -1073, -1431, -1073

Thanks for the notice about the missing checks of the Handled property. I added the checks now (WPF control only), I hope I got it right.

I don't understand completely your question, but at first glance: won't it be enough for you to set the Maximum/Minimum of the axis?

                LogarithmicAxis axis1 = new LogarithmicAxis();
                axis1.Position = AxisPosition.Bottom;
                axis1.Base = 8;
                axis1.MinorStep = 2;
                axis1.MinorGridlineStyle = LineStyle.Dot;
                axis1.MinorGridlineColor = OxyColors.LightGray.ChangeAlpha(20);
                axis1.Minimum = 0;
                axis1.Maximum = 32800;

                plotter.Model.Axes[0] = axis1;
                plotter.RefreshPlot(true);

Results:

Log2


Log8


Log10




I think you can't retrieve the label for minor ticks right now, correct if I'm wrong.

By the way: why would you set the base to "e"? Its logical to obtain "random" values (e^2, e^3...)

Hi everyone,

with a couple of friends of mine we're starting one project of a Metro-style app and we're evaluating Oxyplot as our charting library.

But here we come to the problem: I've tried installing Oxyplot with NuGet, via Package Manager Console or manually adding the references, none of this methods worked.

The problems seems to be with metro project, because with wpf app I don't have this issue and everything works just fine.

Do you plan to add the support to Metro app?

So, let's recapitulate:
- VS 2012 Pro
- Win 8 RTM x64 eng
- Oxyplot 2012.3.127.1
- Metro project

I've actually attached a print screen of the failing setup as well as the output of the Package Manager Console.

Any help will be much appreciated, thanks

Yes, a Metro version is planned, and a NuGet package will be added when it is done! I will start testing on Windows 8 soon. See the fork http://oxyplot.codeplex.com/SourceControl/network/forks/elliatab/MetroFix, I plan to merge this into the main branch soon.

objo wrote at 2012-08-24 14:44:

Is it possible to build a Metro project on Windows 7? Otherwise I need to move the build server to Windows 8 before I can create the nuget package automatically. The Oxyplot library will be PCL.

poweramd wrote at 2012-08-24 15:43:

Hi objo,
thanks for your reply.

So, first, I think we can wait the release of Oxyplot for Metro. We have much work to do before plotting the results, so, no problem. I'm happy to know that you're working on.

Second, I'm not really sure if you can build a Metro app in Win 7. When developping for WP7 there was an emulator of the phone, I don't know if there is something similar. If I have some spare time, I'll try to install VS2012 on Win 7 and let you know what happen.

poweramd wrote at 2012-08-24 23:35:

Well, it seems that you cannot create Metro project if running VS 2012 on Win 7...
