Hello Narcis,

Changing the following lines

Code: Select all

      'bmp = New Bitmap(chart.Width, chart.Height, PixelFormat.Format32bppArgb)
      'g = Graphics.FromImage(bmp)
into

Code: Select all

      g = chart.CreateGraphics
solves our problem, the reason remains unclear to me...


Regards, Jan

Gridlines and DashStyle

Hello, We export a tchart to a metaFile. Solid Lines look the way they should but other styles (like dot, dashdot or dashdotdot) are too big. Compared to a line with the same height and width it looks about twice as fat. When printed out or in preview mode it's almost impossible to see that the styl...
