Re: [amibroker] Re: PlotText problem when using SelectedValue, AmiBroker Email List Archive

Try this code:

SlopeTest = LinRegSlope( C, 10);

PlotText( "Slope\n "+ NumToStr( SelectedValue( SlopeTest ) ),
SelectedValue( Cum(1) ), SelectedValue( L) , colorBlack);

That is pretty weird that it's working for you and not me.

I pasted your code into a blank AFL and applied it. The text shows up
on the bar where the selection happened to be. But as soon as I select
a new bar, no new plot text of slope values appears anywhere. Of
course I tried selecting many different bars and still no text.

There must be some other funky setting or preference in my Amibroker
itself that is preventing the selection from working. Haven't yet
figured out what that could be. Any suggestions welcome.

On another note, how did you paste your code into Yahoo with all the
colors properly set? When I paste from Amibroker into the Yahoo Group
using the Rich-Text Editor, the code is in black and white. I then
sometimes change the text colors manually.
