![]() The result is an EMF which contains the chart as well as the extra lines as vector elements. (I found the code for creating and saving a new EMF here.) Using (var igfx = Graphics.FromImage(mf)) Using (var mf = new Metafile(MyFilename, gfx.GetHdc())) Recently, I started exporting my Matlab figures to illustrator in order to touch them up for publication. ![]() "this" can be the form, that will be sufficient Now, we can save the chart to a temporary memory stream, read that stream again and overlay the drawing with the extra lines: MemoryStream ms = new MemoryStream() It should look like this: private void Chart_Paint(object sender, PaintEventArgs e) Produces code for directly embedding equations into HTML websites. Ok, finally I worked it out, this is the most simple solution I could come up with.įirst, refactor your Chart_Paint method so you can reuse the drawing of those additional lines outside of the Paint event. HTML LaTeX equation editor that creates graphical equations (gif, png, swf, pdf, emf). NET provides something else for drawing vectors (appart from using a chart.Series object, but I can't find a way to do so while using a custom pen. I feel like there's no way to make DrawLine() draw vectors, but I don't know if. I can export an emf file using the last line with the bmp.Save method, but it's not drawn using vectors (I can't import it to Inkscape and save an eps file for instance). G.DrawLine(new Pen(Color.Black, 2), new Point(0, 0), new Point(, ChartImageFormat.Emf) // The drawn lines are .Png) // Every drawn line .Emf) // Every drawn line appear but saved as a bitmapīut I still can't find a way to export these lines in a vectorial image. Using (Graphics g = Graphics.FromImage(bmp)) I tried exporting the chat as a bitmap to check if the drawn lines were exported, and it worked (the following code saved the aforementioned image with the lines displayed): using (Bitmap bmp = new Bitmap(, ))Ĭhart.DrawToBitmap(bmp, new Rectangle(0, 0,, )) Is there a way to keep these lines in an emf export? I then want to export my chart as an EMF file (to be later be included in LaTex), ChartImageFormat.Emf) īut then my lines drawn in the Paint event handler are missing: chart as exported in emf. G.DrawLine(pen, pointsList, pointsList) Įverything works fine, and my chart looks like I want it to look:Ĭhart as displayed when the software is running. List pointsList = points.Select(p => new Point((int)(p.x), (int)(p.y))).ToList() įor (int p = 1 p < pointsList.Count p++) G.SmoothingMode = .AntiAlias įor (int line = 0 line points = _meanLines.Select(mean => (float.Parse(mean.x) * (1 + _xOffset), mean.y)).ToList() The Paint event looks like the following (it has some custom shenanigans for offsetting each curve along the x-axis): private void Chart_Paint(object sender, PaintEventArgs e) However, I link the error bars' middle points with a drawing in the Paint event handler, since series doesn't seem to be drawable with custom pens. ![]() I plot error bars using chart series (with the () method). for creating connections between nodes.I'm drawing some data using Winforms (with a C# solution).
