Chart export feature wish list
Posted: Sat Oct 27, 2007 2:51 pm
Hi there,
I have trouble exporting the chart shown on screen exactly as that into a graphics file, so it can be used in some kind of printed report.
While bitmap file export is great when you want to use the bitmap for screen display only, the resolution is too small when it should be used in a 600 DPI print. It would be nice to have a feature that allows scaling the chart's resolution yet keeping all the axis scaling the same. This is probably hard to do, so I guess this is a low priority feature wish.
Alternatively printing the chart into a PDF (using PDF creator) seems to reduce the quality. For instance, the grid lines become grey solid lines. But this may be a printer setting problem, I have to investigate that further.
Anyway, the desired way of getting chart data into printable documents (word, latex) is to use some kind of vector graphics format. However, with _all_ export methods I observed some problems:
EPS - the fonts are not converted correctly (this seems to be a known problem, since there are posts about this issue already)
PDF - the axis captions overlay the labels, while for the chart on the screen it is possible to specify the LabelsSize property, for the export the default algorithm seems to be used which causes this overlaying of axis caption and labels
EMF - probably the best export and closest to the original, but the text seems to be squeezed in some parts as if the character distances where not correctly calculated. This is a minor glitch though, but visible.
SVG - vertical axis captions are not rotated. Apart from that the export seems to be pretty good and gives as the only export option an editable chart.
From the user's perspective PDF export and SVG export should be improved in the next versions, both with the aim to produce exported charts that are as close as possible to the original chart that you view at the screen.
Despite all the minor flaws, thanks for supporting so many different formats and improving the export features of TeeChart in the future.
