[REBOL] Re: Plotting Dialect and Docs Available

From: ddalley:postoffice:idirect at: 27-Jan-2002 22:19

Hello, Matt: I apologise for taking so long to get this out, but I actually lost my first reply. This silly keyboard design has a power On/Off key right above the cursor keys, and one small mistake can spell disaster for unsaved work. <grrr> Sent: Wednesday, January 23, 2002 10:42 PM Subject: [REBOL] Re: Plotting Dialect and Docs Available I had a quick look at the stock graphing abilities you added to your plotting dialect. Good work! Some comments, in no particular order, will follow. Please keep in mind that I have a narrow interest in plotting/graphing - stock charts and related graphing. Others may voice their own concerns.

It is easy to set up one at any of the free sites; I use, in Hong Kong, for my WWREB site.

I figured the files went somewhere because the desktop's "R" symbol cycled, but I didn't have a clue where, until I went digging for the files. OK, let's see if I can remember what I lost. You have no XY label margins to seperate the plot data from the lables. This does not look good. Ah, I see - the lables are inside the plot area, so a way of placing them outside would fix this. Of primary importance today is the ability to use Japanese candlestick bars. These quickly and easily display emotion by using a fill colour: your standard tick bars can't do this. Is there a way to automatically find an unused area, to place text over data without messing up the line displays? Just curious... Maybe a way of adding a background colour to the text would help. For stock price charting in particular, there should be a semi-log scale available. There should be some way of controlling how many date labels get displayed, when there is a lot of data, otherwise dates overlap. The two date examples show overlapping. You have a neat feature that allows drawing on the plots. Can you make it so that we can save this new information, in some way? This would be useful to save, say, trendlines. Maybe a way of click&type (to add comments) would work, too. Is there a way to limit/scale the size of the main window? The document displayer that works with your docs does not disappear below an additional toolbar, on Windows' desktop. The plot windows, if big enough (as it is with IBM's current data), do disappear behind it. I realise it is more of an OS/REBOL thing. Without actually using your dialect, that's what first comes to mind, in the way of comments. My hands are full, for the moment, but I will get to use it, as soon as possible. Thanks for your efforts regarding this and I do hope you find these suggestions useful and practical. If I can help you in any way, please call. Donald Dalley
