UPDATED QUICK PLOT DIALECT and Tutorial
[1/7] from: lcdr:licholai:msc:navy:mil at: 22-Feb-2002 12:00
All, I updated the quick plot dialect (q-plot) and ez-plot tutorial posted on the reboltech site. Some of the changes to the quick plot dialect include: * added pie charts and exploded pie charts * added scatter plots * added candlestick charts for displaying stock data * added the ability to place axis in a border area * added logarithmic, and semi-logarithmic scale options (and also a dynamic selection mode) * modified text placement to accept relative positioning of the text * added a style options to the title * better use of parse to implement the dialect * internal code clean up The ez-plot tutorial has also been updated to reflect the changes in quick plot. Additionally, the tutorial has an expanded section on using quick plot, get-stock.r and condense.r (some functions to aggregate data) to create a stock analysis application. Although some of the internals of quick plot still look like spaghetti, I have tried to improved the readability and REBOLness of the code. In some ways I again prove that you can write passable FORTRAN in REBOL. Once again I welcome all comments on the usability, style and functionality of the dialect and the code. Thanks, Matt

Wow: Great work... Thanks. Error: When I try the last demo in Additional Examples' section [drawing on graph and saving snapshot], it hangs as soon as click "save Image". Question/Suggestion: Is there any reason in "Stock[OHLC]" why not to directly download the needed file %get-stock.r if it is not found? Yes there is text warning there, but is too easy to break lovely demo application. At least if is not found, then app should not crash - instead just prompt. Boring I know, but this is what breaks so many REBOL/View programs.. they just hang when they should ignore. Search Issue Related to this, does anyone have any ideas how to improve google searches for rebol scripts. For example, search google for get-stock.r %get-stock.r rebol get-stock.r rebol %get-stock.r all => return nothing. I imagine this is because rebsites are not visible to google. If so, would'nt it be useful to have a %make-rebsite-interface-to-google.r script? An ideas how to do this nicely..? thanks again ./Jason

Brett, Thank you for providing the URL. I don't often monitor this list on weekends. Thanks, Matt
