Bartek, Looks like the code you are looking for is in the Nplot library file: Windows.PlotSurface2D.cs in the DoMouseMove function. Look for "if ( coordinates_.Active )" - the code you need is after the "if". I tried this: If you create a MouseClick event for your plotsurface instance and add the following code: Point here = new Point(e.X, e.Y); double x = plotSurface.PhysicalXAxis1Cache.PhysicalToWorld(here, true); double y = plotSurface.PhysicalYAxis1Cache.PhysicalToWorld(here, true); The x & y should be the coordinates you are looking for. Did you get the source code for Nplot to compile? Deb -----Original Message----- From: Bartek K [mailto:mor...@gm...] Sent: Monday, April 21, 2008 9:45 PM To: npl...@li...

I am using VS2005 .NET 3.0, C#, Windows XP. The Nplot library (version 0.9.10.0) works great – except,
1. When the context menu option ‘Original Dimensions’ is clicked, it display all of the labels on the x axis in a clump. The PhysicalSpacing min is set to 25 – which works fine until the ‘Original Dimensions’ is clicked.
2. When expanding the x-axis – if it is expanded too far, it bombs in NPlot.Axis in the Draw routine: {"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index"} at the line: “this.DrawTicks( g, physicalMin, physicalMax, out labelOffset, out tickBounds );”
I wanted to compile NPLOT to debug the problem, but cannot. There are 2 errors:
“System.Windows.Forms.PaintEventArgs does not contain a definition for X”
“System.Windows.Forms.PaintEventArgs does not contain a definition for Y”
I have installed MSBEE. Can you help point me in the right direction?
Thanks, Deb

Hi Mark Also, in general, you can register for COM interoperability without the source code by using the "regasm.exe" from the commandline. See, for example, http://edndoc.esri.com/arcobjects/9.2/NET/9826f81b-278c-49cc-a912-ab8d86f5e91e.htm You will have to do > regasm.exe <path to>/NPlot.dll /codebase ( the /codebase option is necessary unless the NPlot.dll is installed in the GAC). If you want to generate a type library for NPlot.dll that you can use from unmanaged C++, you can add the /tlb: option > regasm.exe NPlot.dll /tlb:NPlot.tlb This will also register the NPlot.dll for COM interop. If you want only a tlb, you will need to download the tlbexp.exe tool that's available in one of the SDKs (but not by default in the .NET 2.0 Framework). See http://www.microsoft.com/downloads/details.aspx?FamilyID=fe6f2099-b7b4-4f47-a244-c96d69c35dec&displaylang=en Regards, Jim On 3-Apr-08, at 6:49 AM, Jamie McQuay wrote: > > Hi Mark, > > Getting NPlot to work as an interop dll is not to hard to do. > > You will have to get the source version of NPlot from the trunk folder > from svn. > > 1.

Hi Mark, Getting NPlot to work as an interop dll is not to hard to do. You will have to get the source version of NPlot from the trunk folder from svn. 1. Open the source in visual studio 2. Open the properties page 3. Click on the Build tab 4. Check the "Register for COM interop" checkbox 5. recompile Now you have a dll that you can access from unmanaged C++ using the COM interface.

How to Reproduce: Create a bar plot with the bars filled in vertical gradient mode (color changes along the y-axis). Manually resize the containing window until one of the bars becomes zero pixels high (with a non-zero data point). As soon as this happens, the application will crash with an unhandled exception. Recommended Fix: Before painting the bar for a data point, check for zero height. If zero height, maybe draw a single pixel line at that point, but don't bother creating the rectangle or gradient fill brush. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=821568&aid=1916843&group_id=161868 |

MT,
Cross thread UI interaction is a big headache I've found.
I've since moved from using the Form thread timer to a
System.Threading.Timer. This way I can have an intermediate object
receive events from the environment (tick server) and then build OHLC
bars there. A form (or whatever object that needs to consume bars - 1
second, 5 second, 1 minute, etc.) requests a certain periodicity from
the barbuilder object. This object then creates a Threading timer
which emits bars at the specified interval. The form then consumes
those events, saves the bars in a cache (datatable) and on that event
repaints the graph.
The problem of course is that this object's Threading timer thread is
cross threaded from the form. And so I must perform a
this.InvokeRequired test and use that method delegate:
if (this.InvokeRequired) {
this.Invoke(new MethodInvoker(ProcessLatestQuote));
return;
}
Even so, I'm getting what appear to be cross thread lockups at update
frequencies of 2 seconds or less. So I'm thinking that in order to
avoid these lockups I must do nothing aside from update a local cache
of quotes on the Threading timer event - and get out fast.
And then to lock(cache) {} while I perform a graph update.
Sorry if this appears off-topic for this list. But the concept of
graph updates on timers and cross threading is an issue that many will
encounter when using NPlot to graph real time data.
Regards,
Dave Cline

Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: randalx (randalx) Assigned to: Jamie McQuay (jamcquay) Summary: Problems ploting single point Initial Comment: Hi, My program plots various LinePlots and PointPlots using the AbscissaData and OrdinateData. The data can change based on user interaction. A bug occurs when the data is for only one point. First there is an exception in DateTimeAxis.cs void DrawTicks(...) { ... PointF lastPos = WorldToPhysical((double)largeTicks[0], physicalMin, physicalMax, true);//ed The exception is due to accessing largeTicks[0]. The previous call to WorldTickPositions() fails to add any data to the largeTicks array. A quick fix was to add the following code: if (largeTicks.Count <= 0) { return; } But the result is not very satisfactory as I'd still like to see the point plotted. My temporary hack was to adjust the XAxis1.WorldMax and XAxis1.WorldMin by 100 so as to show a centered point but this is far from ideal.

I would like to export the plot surface to image (jpg, png, ..). Is this currently possible with NPlot? I'm using NPlot to plot charts like this<http://img3.freeimagehosting.net/uploads/dc4ac47fdd.png>. The thing is that the bottom surface can contain outliners. The result is that the outliners cause the ax values to take on absurd proportions (accommodate for the outliner). Is it possible to apply break lines? For example like this<http://img3.freeimagehosting.net/image.php?fa9a921adc.gif>, but a break line on the ax would be fine as well. I was trying to understand the NPlot library by looking throught the source code and documenation, but it's kind of hard to see how all the pieces fit together as a C# beginner. Any suggestions as to where to start? Regards, Jan |

Category: General Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Matthew McDougal (mmdoogie) Assigned to: Nobody/Anonymous (nobody) Summary: Y Axis recommendation extended while X Axis is not Initial Comment: I ran into a problem that I wouldn't have even noticed had I not been trying to use a LogAxis as the Y Axis on a plot. myPlotSurface.YAxis1 = new LogAxis(myLinePlot.SuggestYAxis) When I then tried to refresh my plot, it would fail saying I can't have negative data on a log axis, but of course I didn't have any negative data. Looking at the SequenceAdapter code in SVN, which I've trimmed a little just to get the relevant parts: public Axis SuggestXAxis() { Axis a = this.XAxisSuggester_.Get(); // The world length should never be returned as 0 // This would result in an axis with a span of 0 units // which can not be properly displayed. if (a.WorldLength == 0.0) { a.IncreaseRange(0.08); } return a; } public Axis SuggestYAxis() { Axis a = this.YAxisSuggester_.Get(); a.IncreaseRange(0.08); return a; } Basically, what occurs is on the X axis, the range is only increased if the returned axis was zero, but on the Y axis, it is always increased by +/- 8% of the range. If your span is sufficiently large enough, and your lower limit close enough to zero, the range can get extended negative. There may be a reason I don't know about, but if there isn't, I would suggest making the Y axis behave in the same manner as the X axis. --matt ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=821568&aid=1901521&group_id=161868 |

There seems to be no way to get LabelPointPlot to work in NPlot.Bitmap.PlotSurface2D. Every attempt I make results in a completely different exception being thrown either upon adding the LabelPointPlot to the graph or upon calling refresh(). For example: NPlot.LabelPointPlot lpp = new LabelPointPlot(); lpp.DataSource = xPositions; //an int[] lpp.OrdinateData = yPositions; //an int[] lpp.TextData = labels;//an string[] lpp.AbscissaData = XAxis; //an int[] graph.Add(lpp); Am I doing something wrong or is this a bug? |

Category: General Group: None >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: Eyal (eyal0) >Assigned to: Angel Marin (anmar) Summary: CandlePlot should use ILists, not Arrays Initial Comment: The IList is a parent class of the Array. LinePlot expects input data to be IList, but CandlePlot uses Array. I fixed this in the patch below. Also edited the text of some exceptions to be more accurate. ---------------------------------------------------------------------- >Comment By: Angel Marin (anmar) Date: 2007-10-04 12:52 Message: Logged In: YES user_id=627967 Originator: NO Patch applied to trunk (r31) with slight modification thanks!
