How to change the charts base instrument (period, type, basetype) with an indicator?

[wjadevries]

I would like to reset a charts base instrument from within an indicator function so that the chart and all indicators on the chart are reloaded, just like I changed it from the chart's instrument window.
So something like:

Chart.BarsPeriod.BarsPeriodType = BarsPeriodType.HeikenAshi;
Chart.BarsPeriod.BaseBarsPeriodType = BarsPeriodType.Tick;
Chart.BarsPeriod.BaseBarsPeriodValue = 1000;

Is that possible and how?

PS: I'm not talking about adding a dataserie for an indicator, I really want to reload the whole chart with all indicators (with a different chart instrument setting).

Hello wjadevries,

It is not possible to manipulate the data series or chart directly from code like that, you would instead need to work with keyboard events to simulate manual keyboard changes.

You can see the rollover indications indicator for an example of changing the instrument.

Nope, already found it myself.
Code is:

ChartControl.Dispatcher.InvokeAsync((Action)(() =>
{
try {
NinjaTrader.Gui.NinjaScript.AtmStrategy.AtmStrategySelector atm = Window.GetWindow(ChartControl.Parent).FindFirst("ChartTraderControlATMStrategySelector") as NinjaTrader.Gui.NinjaScript.AtmStrategy.AtmStrategySelector;
for(int i=0; i<atm.Items.Count; i++) {
try {
NinjaTrader.NinjaScript.AtmStrategy strat = (NinjaTrader.NinjaScript.AtmStrategy)(atm.Items[i]);
if (strat.DisplayName==cs.strategy.DisplayName) {
atm.SelectedIndex = i;
break;
}
} catch(Exception) {}
}
NinjaTrader.Gui.Tools.AccountSelector acc = Window.GetWindow(ChartControl.Parent).FindFirst("ChartTraderControlAccountSelector") as NinjaTrader.Gui.Tools.AccountSelector;
acc.SelectedAccount = cs.account;
Print("account set");
NinjaTrader.Gui.Tools.InstrumentSelector inst = Window.GetWindow(ChartControl.Parent).FindFirst("ChartWindowInstrumentSelector") as NinjaTrader.Gui.Tools.InstrumentSelector;
inst.Instrument = cs.instrument;
Print("instrument set");
NinjaTrader.Gui.Tools.IntervalSelector interval = Window.GetWindow(ChartControl.Parent).FindFirst("ChartWindowIntervalSelector") as NinjaTrader.Gui.Tools.IntervalSelector;
cs.interval.BarsPeriodType = BarsPeriodType.Tick;
interval.Interval = cs.interval;
Print("interval set");
} catch (Exception e) {
Print(InternalName + this.Instrument.FullName + ":" + e.Message);
}
}));
