    Default Can Qwt be used for financial charting? (bar chart, candlestick)

    I know Qwt is probably more scientific focused than finance, but since there is a lot of overlap, I'm wondering if anyone's implemented a candlestick charting or at least a bar chart (open, close, hi, low). Are there any examples of this?

    Is this incorporated into the new version or does one have to patch it themselves?

    You can extend Qwt by implementing custom plot items. This code is such an item, so it is simply application code, that you have to copy into your application ( or use it as an inspiration for your own implementation ).

    My plans are to have this type of financial items in the next Qwt release, but the API will differ.

    Hi Uwe,

    I found this thread very useful for myself. I read the conversations from the link provided above. I saw the screenshots ... I've seen the main.cpp with the example how to draw candlesticks, but I can't find anymore the source file: qwt_plot_price.cpp in SVN. Additinally, qwt_series_data.cpp + qwt_plot_item.h from the last revision (> 700) do not contain any QWTPriceMove class and Rtti_PlotPrice. Neither revision 517 doesn't contain them.

    Can you please let me know where can I find these files or if it's easier please forward them by email( victor_pas@yahoo.com )? I am very interested in creating charts using financial data.

    Thank you in advance and best regards,
    Victor

    Qt Code:
    1. svn co https://qwt.svn.sourceforge.net/svnroot/qwt/trunk/qwt
    To copy to clipboard, switch view to plain text mode
