    Draw.Region not working when I use additional DataSeries

    My indicator has two plots and a region being drawn. I also have a switch (bool) to indicate whether or not these values should be plotted according to a different time frame (data series). The idea is to plot a MA channel on the chart, optionally using values from a higher time frame.

    When I use the chart data series, the plots are correct and the region is drawn.

    When I use the secondary data series, the plots are correct, but the region is not drawn.

    Is there something wrong with the code below that prevents the region from being drawn?




    Code:

    Code:
    if (State == State.SetDefaults)
    {
    UseHigherTF = false; TF1 = 5; TF1Type = Data.BarsPeriodType.Minute; Period = 5; ChannelBrush = Brushes.Black; ChannelOpacity = 50; AddPlot(Brushes.Orange, "UpperLine"); AddPlot(Brushes.Orange, "LowerLine"); Plots[0].Width = 2; Plots[0].Brush = Brushes.Black; Plots[1].Width = 2; Plots[1].Brush = Brushes.Black;
    } else if (State == State.Configure) {
    if(UseHigherTF == true) {
    AddDataSeries(TF1Type, TF1);
    } SetZOrder(-1);
    } else if (State == State.DataLoaded) {
    if(UseHigherTF == true) {
    SMMA1 = smittySMMA(Highs[1], Period); SMMA2 = smittySMMA(Lows[1], Period);
    } else {
    SMMA1 = smittySMMA(Highs[0], Period); SMMA2 = smittySMMA(Lows[0], Period);
    }
    } protected override void OnBarUpdate() {
    if(CurrentBars[0] < Period) { return; } if(UseHigherTF == true) {
    if(CurrentBars[1] < Period) { return; }
    } Values[0][0] = SMMA1[0]; Values[1][0] = SMMA2[0]; Draw.Region(this, "MA Channel", CurrentBar, 0, SMMA1, SMMA2, null, ChannelBrush, ChannelOpacity);
    }

    Hello torch2k,

    Drawing objects are attached to the primary series only. A secondary series would not have the same chart slots and would not allow this to draw.

    You could create a custom series, and then set the value of this to the higher time frame plot.

    Below is a link to an example with a similar idea.

      Makes sense - thank you!
