Hello,
Thank you very much for your detailed and
constructive feedback. It is appreciated.
As for +/-10 layers - I would need to check if this would not
degrade performance plus I am not sure if having 20 options
in the Format->Z-order menu would be pleasing to the eye,
but anyway that will be considered.
Rectangle/ellipse fill color - yes it is blend of
background and study color at the time of creation of the study. Subsequent
changes
of background color don't affect already drawn
studies.
Blank space - yes it gets reset once you switch to different
symbol and yes it is so to enable you actually go back
to "normal" once large space is no longer needed. I also was
thinking about checkbox to switch this off because
as history teaches not everyone likes the changes, but your
suggestion of adding "maximum" setting is
even better. Anyway I was just thinking that on-the-fly
extension is nice to have because it saves a lot of mouse clicks
(instead of going to Preferences over and over
again).
As for "pixel" dimension - I am not big fan of that as
that would generate lot of headache when coding as charts and scroll bar logic
is based
on bars everywhere in the program as "pixel" is not relevant
and changes pretty often (zoom, printing, copy image, metafile
output
- all these have completely
different DPI).
Anyway, something to think over.
Best regards,
Tomasz Janeczko

Tomasz,
Thank you for providing all
the new charting capabilities. I have much praise and also some other
feedback from my first hour of use and adding the new AFL features to my
program already.
• X-Y co-ordinate labels on axes implemented. Can be controlled using
View->X-Y labels menu.
This is great!
I can now ditch the one I just finished writing -- LOL! Yours is
much better. I like the shadow effect to make it stand out
better.
• Plot, PlotForeign and PlotOHLC now have new parameter zorder which
defines the Z-axis position of given plot
• All drawing tools now can define Z-order (from -5 to +5).
This is great, but it would be
even better if it were -10 to
+10 layers, though I could get by
with 8. 5 are enough layers for groups of plots, but not quite enough
for my individual plots, so I still have to break my plotting routines from my
modular function generation code. With 10 layers above and below, I
could have enough layers to make my functions truly modular.
I absolutely love that the
default study lines are below the Gfx plots. My studies no longer
obscure my on-chart button arrays and information tables.
• new AFL functions ColorBlend
This is great! A way to
select colors by stepping through values in a way that makes sense to the eye.
I will have to think of a way to include this in my charts.
• Rectangle and Ellipse drawing tool now are by default SOLID, with
default fill color being a blend between background and selected drawing
color, they are use ZOrder = -1 (behind regular plots) by default
This is a great improvement!
Though I must not understand what you mean by blend between
the background. I changed chart background colors and it did not change
the color of the oval I was testing... Wait, I just figured it out.
It uses the color of the background when you create the object only and
does not change it dynamically after that.
• Blank area past last available quote can be now enlarged on the fly by
simply using > arrow in the scroll bar or using mouse wheel
This one is causing me some
difficulties. I both love it and hate it.
I love that I can increase
the space easily.
I hate that it has no
limits and once increased, it becomes the new default for the position thumb
all the way to the right.
I hate that if the symbol
is switched, it does not remember what it was last set to, though that seems
to be the only way to reset it back to the default.
If I want to increase the
space, it is usually to a constant PIXELs of blank space so that I can fit
objects that are pixel based to the right of the chart in the blank area.
So being able to increase the blank area if I am zooming out to many
bars is a good thing.
However, I very often use
the scroll wheel to move back an forth in the chart during real time trading.
I move left to see some last support level for setting a study point,
then I give the scroll wheel a quick zip to get back to the right default
position again for trading the current bar. With this new mode, I zip
right past all the bars to a blank chart and am lost in white
space.
So this feature is causing
me more problems than not having it at all. I don't really need the
ability to add unlimited white space.
What I need is one of the
following:
1a A way to turn this
feature off, or
1b A maximum amount of
white space preference that the scroll wheel can't exceed -- preferably with
either bars or pixels options.
1a A way to turn this
feature off, and
2b A preferences checkbox that allows pixels
rather than bars of default white space, or
2c An AFL function to set
the amount of future bars that overrides the default.
Thank you for being such a
great developer that listens to your customers!
Best
regards,
Dennis
