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

That's strange. Here's the complete code from my version and it works fine for every bar I click/select on:

SetBarsRequired(10000, 10000);



SlopeTest    = LinRegSlope( C, 10);

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


_SECTION_BEGIN("Price");

SetChartOptions(0,chartShowArrows|chartShowDates);

_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));

Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() ); 

_SECTION_END();

Try copying/pasting this ......

Thanks but that does not make a difference as I already had that line
in my code.

corrected, the slope appears on the selected bar when I first apply
the indicator. But as soon as I select another bar, a new value does
not appear. And even if I go back to the original bar, no more values
of slopes are visible on screen:
