"Edit Strategy" Menu - Adjustable brush attributes

[smcllr]

The following is all of the pertinent info that I have added to a strategy which adds a particular plot line.

What must I add to this script to be able to change brush attributes in "Edit Strategy" menu? I can see the brush attributes but they are grayed out and I am not able to adjust them.

Thanks,

           AddPlot(Brushes.MediumSeaGreen, "MyPlot1");

else if (State == State.DataLoaded)
            {​

                EMA5                = EMA(Close, 35);
                RMA1                = RMA(TrueRange(1), 35);​
            }​

        protected override void OnBarUpdate()
        {    
            if (BarsInProgress != 0)
                return;

            if (CurrentBars[0] < 20)
                return;

            double rma0            = RMA1[0];
            double ema0            = EMA5[0];

            if (CurrentBar == 0)
                MyPlot1[0] = Median[0];
            else
            {
                MyPlot1[0] = ema0 + (rma0 * 0.5);
            }​
        [Browsable(false)]
        [XmlIgnore]
        public Series<double> MyPlot1
        {
              get { return Values[0]; }
        }
    ​

I found that adding

ArePlotsConfigurable = true;

made them editable.
