Indicator data not shown

[chinaski]

Hello,

have a strange problem. Data of my simple indicator are not shown, if the outside a specific level BUT still in scale range.

The code below demonstrates this. If you select threshold >= 0.9, you can't see any dot in the indicator value. The value is a Sin(x), so between -1 and 1.

To prove there are values, i do also a debug out along with date. Any help appreciated, thank you.

#property indicator_separate_window_window
#property indicator_buffers 1
#property indicator_plots   1
#property indicator_type1   DRAW_LINE
#property indicator_color1  White

//--- input parameters
input double         InThresholdLevel=0.9;         // InThresholdLevel
//--- indicator buffers

double          data[];
void OnInit()
{
        SetIndexBuffer(0,data,INDICATOR_DATA);
        IndicatorSetInteger(INDICATOR_DIGITS,10);
        PlotIndexSetInteger(0,PLOT_DRAW_BEGIN,0);
        //---- line shifts when drawing
        PlotIndexSetInteger(0,PLOT_SHIFT,0);
        PlotIndexSetString(0,PLOT_LABEL,StringFormat("indi",0));
        
        IndicatorSetString(INDICATOR_SHORTNAME,"indi");
        PlotIndexSetDouble(0,PLOT_EMPTY_VALUE,0.0);
//---- initialization done
}

void OnDeinit(const int reason)
{

}
double get_level(int i)
{
        return MathSin((double) i);
