Fixed [SF patch 1806859]
CandlePlot wasn't accepting input data as IList (only Array) while all util methods can handle it without problems. As Array implements IList, there aren't any backwards compatibility issues.

It looks like the font is not always properly registered with the system. Although this problem is probably a Microsoft issue it does not seem very user friendly to delegate the problem to the end-user. I found a discussion on this topic on the following site: http://www.spheresite.com/forum/read.php?7,92872,93423 Maybe an exception has to be generated "Font arial is not properly installed (in windows), please reinstall". Alternatively a message could be displayed giving this information to the user.

I've written briefly about this issue in the past, but this process was somewhat stalled (mostly on my part). I need a setup where I can click the plot surface of a PointPlot and then get the element that I have clicked. Ultimately the best solution would be to .Add() some kind of point-objects to the PointPlot and then having the PointPlot call some function whenever a Point is clicked. Is it currently possible to do something like this is NPlot?? If this can be done with custom interaction handlers, can someone please point in the right direction about how to do this?

Category: General Group: None Status: Open Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Input parameter validation Initial Comment: This took way too long and it's obviously my fault, but some input parameter validation (and according error throwing capability) would be nice. I didn't set the height or width in the NPlot.Web.PlotSurface2D object I was using and kept getting a "Parameter is not valid" error. This error comes from the first line of the Render() method accessing the height and width members to render the bitmap: System.Drawing.Bitmap b = new System.Drawing.Bitmap( (int)this.Width.Value, (int)this.Height.Value ); Once I set some required properties everything seemed to work pretty well. I like and I'm impressed. Thanks. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=821571&aid=1728620&group_id=161868 |

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. Thanks, Randal ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2007-05-11 01:43 Message: Logged In: NO I have rather similar problem with 5 point at LabelAxis.cs This is Stack Trace of 0.9.9.2 but it happen in 0.9.10.0 as well.

Category: General Group: 0.9.10.0 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Onno the dutchman (onnovl) Assigned to: Nobody/Anonymous (nobody) >Summary: unhandled exception concerning font used in NPlot Initial Comment: Hi Guys NPlot uses call to arial font that causes an unhandled exception to be generated on some systems running windows xp. It looks like the font is not always properly registered with the system. Although this problem is probably a Microsoft issue it does not seem very user friendly to delegate the problem to the end-user. I found a discussion on this topic on the following site: http://www.spheresite.com/forum/read.php?7,92872,93423 Maybe an exception has to be generated "Font arial is not properly installed (in windows), please reinstall". Alternatively a message could be displayed giving this information to the user. Cheers Onno System.ArgumentException: _Font 'Arial' does not support style >>> 'Regular'._ >>> at System.Drawing.Font.CreateNativeFont() >>> at System.Drawing.Font.Initialize(FontFamily family, Single emSize, >>> FontStyle style, GraphicsUnit unit, Byte gdiCharSet, Boolean >>> gdiVerticalFont) >>> at System.Drawing.Font..ctor(FontFamily family, Single emSize, >>> FontStyle style, GraphicsUnit unit) >>> at NPlot.PlotSurface2D.Init() >>> at NPlot.PlotSurface2D..ctor() >>> at NPlot.Windows.PlotSurface2D..ctor() ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=821568&aid=1713592&group_id=161868 |
