<FONT face=Arial color=#0000ff
size=2>Dean,
in
help click the AFL icon on the tool bar. Syntax and examples for writif() and
writeval() can be found there. Here is a simple example
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>Plot(c,"price",colorgreen,stylecandle); //plots a simple candle
chart
<FONT face=Arial color=#0000ff
size=2>
since
we are plotting close then AFL will by default place the close value in the
title line of the chart. By adding a Title expression we gain far more
flexibility...
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>title=" Close "+C+" High "+H;
<FONT face=Arial color=#0000ff
size=2>
We can
gain a bit more format control using writeval()
<FONT face=Arial color=#0000ff
size=2>
<SPAN
class=246284504-21042004>title=" Close
"+C+" High "+H+ "Average Price "+Writeval((h+l+c)/3,1.2); //where 1.2
offers us 2 decimal places
<SPAN
class=246284504-21042004>
<SPAN
class=246284504-21042004>Writeif allows us to add conditional
text....
<SPAN
class=246284504-21042004>
Title<FONT
color=#282828>=" Close "<FONT
color=#282828>+C<FONT
color=#282828>+" High "<FONT
color=#282828>+H+
" <FONT
color=#ff00ff>Average Price "+<FONT
color=#0000ff>WriteVal((H<FONT
face=Arial>+L<FONT
color=#282828>+C<FONT
color=#282828>)/3<FONT
color=#282828>,1.2<FONT
color=#282828>)+ <FONT
color=#0000ff>WriteIf(V<FONT
face=Arial>>Ref<FONT
color=#282828>(V<FONT
color=#282828>,-1<FONT
color=#282828>)," Increasing Volume"<FONT
color=#282828>, " dwindling Volume"<FONT
color=#282828>);
Using
encodecolor you can even chane the color of portions of the
title....
Title=<FONT color=#ff00ff
size=2>" Close "+<FONT
size=2>C+<FONT color=#ff00ff
size=2>" High "+<FONT
size=2>H+ <FONT color=#ff00ff
size=2>" <FONT color=#ff00ff
size=2>Average Price "+<FONT
color=#0000ff size=2>WriteVal((<FONT
size=2>H+<FONT
size=2>L+<FONT
size=2>C)/<FONT color=#ff00ff
size=2>3,<FONT face=Arial
color=#ff00ff size=2>1.2)<FONT
face=Arial color=#282828 size=2>+ <FONT face=Arial color=#0000ff
size=2>WriteIf(<FONT
face=Arial size=2>V<FONT face=Arial color=#282828
size=2>>Ref<FONT
face=Arial color=#282828 size=2>(<FONT face=Arial
size=2>V,-<FONT
face=Arial color=#ff00ff size=2>1<FONT face=Arial color=#282828
size=2>),EncodeColor<FONT
face=Arial color=#282828 size=2>(<FONT face=Arial
size=2>colorBrightGreen<FONT face=Arial color=#282828
size=2>)+" Increasing
Volume", <FONT face=Arial
color=#0000ff size=2>EncodeColor<FONT face=Arial color=#282828
size=2>(colorRed<FONT face=Arial
color=#282828 size=2>)+" dwindling
Volume")<FONT color=#282828
size=2>;
For more examples
you should visit the AFL library (from amibroker web
page)......

AMTo: amibroker@xxxxxxxxxxxxxxxSubject: [amibroker] Re:
Display ValuesThanks Jayson - I tried that for over
an hour and I couldn't findanywhere instructions for adding captions to
charts.Please understand I do not have good programming ability - I'm
just trying to find some clear easy examples as a starting point. Thought
I might find these writeval()and writeif() functions somewhere in the
existing indicators but no luck there either. Somewhere that
says these are the instructions for performing this task in a language
that doesn't require programming knowledge - Anything a bit more
specific would be much
appreciated.Regards,Dean
