Dan,
As to error: one user reported problem with Excel
corrupting saved files. Once Excel was CLOSED during saving the image file
- files were OK.
Maybe you had Excel or other program affecting
Windows clipboard operation open?
Personally, I don't have such
problems.

Tomasz,
Hi. I tried the Edit --> Image-->Export to File option to
both .gif and .png. It worked, but I got an error when trying to open
the .Gif and .Png file in a viewer. I'm using the latest beta
4.75.2.
In any case, whether I export or screen copy, on one of the major
advantages of using a tool like HyperSnap is that you can quickly copy a chart
and the edit it. Many times when posting a chart on this forum,
I'm don't want the complete chart, just a portion. Also, HyperSnap
has some simple editing tools that allow you top add text, arrows,
etc. Quite useful to explain things on a chart.
Regarding printing... When I printed a screen shot of the chart, it
was extremely close to the print command copy. Of course, my screen is
1600X1200 resolution, so that might account for the quality.
I'll try modifying AFL to overlay with a rectangle when I get
home. I'm a bit concerned about losing the grid, though.
I'll play with it.
In any case, on a scale of 1-100, the importance of having the
styleCloud and styleClipMinMax is in the 95+ range. The
importance of the small styleCloud/styleClipMinMax issues we've
discussed is in the 1-2 range (VERY low). The issues are minor,
they only occur under certain circumstances, and there are multiple
workarounds. I.e., lot's of upside; very little
downside.
Regards,
Dan.

Dan.

Hello,
I don't see purpose for such program(s) when you have
Edit->Image->Export to File
already available in AmiBroker (saves chart to .PNG or
.GIF). Also available from OLE automation.
As for printing - printing bitmaps is not really the
solution because of the fact that printouts
to look good require much higher resolution than
screen/bitmap. The solution for proper printing
is overlay with rectangle that has the same color as
background. Such rectangle is easy to
draw with Plot function.

Tomasz

Actually, I did
(sort of) solve one problem – printing. Tomasz mentioned that there
was limitation with styleClipMinMax – it did not print
properly. That’s not a big issue IMO, but I wanted to figure
out a workaround to deal with it. I just used a clipping tool
to print the chart.
Regarding the
inverted colors, they are from AFL changes. They are just an
option in the clipping program.
(HyperSnap-DX).
FYI… I’ve
converted two histograms to Cloud charts.

Dan

1. Dan did not solve it. Dan applied my formula
and that's it (he's post was response to my example
formula)
The formula I have posted here produces exactly
the Stochastic chart Dan has
attached.
The second picture has just invereted
colors.
2. styleClipMinMax is available from 4.75.0
beta.
I am not going to remove it unless I find
something better.

Hello
Tomasz,
i’m sorry,
indeed i have not seen your message. Thank you very much
!
It really works
excellent !
I was wondering
how Dan has solved it.
Can you please
tell me if you consider to remove the styleclipminmax function later
?
BTW: Since
which amibroker version is the styleclipminmax available
?
Thanks a lot
!

Did you read MY answer ? I provided you

it.

Ah
Ha!!! Holdin’ back the good stuff! I knew it!
;-)
I fiddled
with the formula for a few minutes and got the attached. This
opens many possibilities.
I’m sorry to
hear of the issues, but I easily live with styleClipMinMax
issues. I never use WMF anyway. I just clip a screenshot
when necessary. For printing, I can clip a screen shot and then
print. This is easy and fast…
Attached are
two images taken using HyperSnap-DX. The inverted
image (white background) is single menu selection – about two
seconds.
Printing is
even easier. You set up the page setup to auto-scale to
page format, and invert black and white. The every printed chart
is automatically scaled and inverted. The printed version
is excellent and almost the same as AB’s.
Please
document this. Even with the limitations, this is VERY
useful.
Regards,
Dan.

Colors and rendition are 100%
correct. Think about it. In your formula color depends on CURRENT bar
value.
So area between CURRENT and NEXT
bar is plotted with selected color. Now when
chart swings above your
"borderline" the color changes from NEXT bar and not in the "Middle"
of the bars.
There is no way to specify time
between bars.
StockCharts are NOT formula based.
They hard coded fills and the simply fill everything above
border line with
one color and everything below
border with abother color.
To create such rendition is
somewhat tricky because it involves overlay of two charts and
appropriate clipping of the drawing
to "appear" as interpolated. This
is also possible using AmiBroker but this method has one problem - it
is not
printer friendly because printer
drivers and windows metafiles can not properly handle clipping
regions.
The same applies to colorizing
Stoch overbuy/oversell levels.
This is can be done using "secret"
style styleClipMinMax:
Stochastic color oversell/overbuy
levels
SetChartOptions(0,0,ChartGrid30 |
ChartGrid70 );
r = StochK(14);
Plot( r,
"StochK", colorBlack );
PlotOHLC(
r,r,50,r,
"", IIf( r >
50, colorRed, colorGreen ), styleCloud | styleClipMinMax,
30, 70
);

Hi
Thomas,
I started
using the styleCloud. I like it for certain types of charts
much better than histograms but I see one issue with it – colors
change with the change of bar value and not with the change over or
under a certain quantitative value. For example, in the
attached Chaikin MF(10) charts of WRES, the AB version shows odd
changes in colors, while the StockCharts version shows the correct
(IMO) rendition.
In the
attached ChaikinStyleCloud.gif chart, look at the 12/7 bar (under
the cursor line). The CMF(10) value for that bar is
“-.07” (negative). The 12/6 value is “.07”
(positive). In the AB version, the cloud color is the
green color of the 12/6 (positive) bar even after the bar drops
below the “0” line between the 12/6 and 12/7 bar. In the
StockCharts version, the color correctly changes at the “0”
line.
Here’s the
color code for the chart:
CMFColor
= IIf(CMFI
>= 0,
PColor, NColor);
Apparently
AB translates this as “when the bar CMF value changes to goes
over 0, change colors”. My preferred translation would be
“when the interpolated CMF value goes over 0, change
colors. I need to report this to Tomasz, but haven’t had
the time.
It looks
like a similar issue. Is this the issue to which you
were referring?
Regards,
Dan.

Hello,
stylecloud looks good, however i have found no
way to plot typical
oversold/overbought areas on any indicator with
cloud correctly.
Can
someone help please ?
