  1. Whoops - missed a step: 3.5) Delete the line in textButton_Click() that sets the chart's gallery.
  2. Software: Chart FX 7 for Windows Forms with the service pack installed. I'm trying to draw histograms (or, indeed, box plots) of multiple series, and to retain the series' labels when I do so. The technique I'm using is to load the series data and to set the current gallery type in the corresponding statistics object. I've now tried several different approaches, and all lead to the statistical series being labelled "Series1", "Series2" etc. To reproduce the issue: 1) Open the PassingData sample. 2) Extend the chart with a statistics extension. 3) Set the statistics extension'
  3. I've created a BoxPlot by feeding it data explicitly (source appended). When I click the Properties icon on the chart toolbar, then click the Series tab, I get a NullReferenceException deep in Chart FX code: at ChartFX.WinForms.Internal.UI.h.e() at ChartFX.WinForms.Internal.UI.h.g() at ChartFX.WinForms.Internal.UI.h.h() at ChartFX.WinForms.Internal.UI.h.OnVisibleChanged(EventArgs ev) at System.Windows.Forms.Control.SetVisibleCore(Boolean value) at System.Windows.Forms.TabPage.set_Visible(Boolean value) at System.Windows.Forms.TabControl.UpdateTabSelection(Boolean updateFo
  4. I've been requested to make a box-and-whisker plot where the user can select between two methods of calculation for the box boundaries: EITHER 25th and 75th percentiles (which is implemented) OR one standard deviation. Is there a way of enabling this in Chart FX 7? My guess is that there isn't, but it'd be good to have that confirmed. - Peter
  5. I'm creating a box-and-whisker plot with several series. To distinguish the series I need to label each series along the X axis, to correspond to the name the user gives to each series of input data. How do I label a series in a box-and-whisker plot? - Peter
  6. I've got a requirement to create charts that are exportable to good old-fashioned Windows Metafile format, so that they can be displayed in a Rich Text Box. GDI+ has problems with anything other than solid lines in WMFs (it dithers them), so all the lines have to be solid. I've created a chart control on a form and have set all the axis and gridline styles that I can find to solid black. The designer contains the code in Listing 1, if anyone wants to check whether I've simply missed something. I've taken out the usual location, dock etc. properties from that listing. When the chart is di
  7. Chart FX 7 for WinForms with statistics extensions - so I think I'm in the right forum, but please redirect me if required :-). I'm trying to create a histogram chart (with multiple series, possibly each with its own histogram) by putting data straight into it, rather than data binding. Code is Listing 1 at the end. Problem 1: The legend is initially displayed correctly, but the series names revert to "Series 1", "Series 2" etc as soon as I do anything using the Chart FX toolbar. If I turn on bin counts via code, the labels stay intact. If I click the toolbar button to show counts, the l
  8. A late response, I accept - but the trick is to reset the stream's position to 0 before reading from it. MemoryStream stream = new MemoryStream(); chart.Export( FileFormat.Metafile, stream);stream.Position = 0; Image metaImage = Image.FromStream(stream); stream.Close();
