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
