you are pushing it to the limits :) 14 islands and 200 generations...its too much by my opinion and you are wasting a computer time

Status changed from New to Refused

there are only 7 islands, because there is no space for morw. But you can easily copy this snippet in CodeEditor and create one that will display islands from 8-14

Please explain what you mean? What do I have to copy where?

it is extending SQ with your own snippets, it is not yet fully documented.

You should go to Code editor, Snippets -> SQ -> Engine Charts, create a new file "GeneticEvoInfo814" and put the code below there.

Then compile it, restart SQ and you'll see new engine chart that shows info for islands from 8-14.

Full snippet code:

package SQ.EngineCharts;

import java.util.ArrayList;

import org.json.JSONArray;
import org.json.JSONObject;

import com.strategyquant.lib.*;
import com.strategyquant.datalib.*;
import com.strategyquant.tradinglib.*;

public class GeneticEvoInfo814 extends EngineChart {
    
    public GeneticEvoInfo814() {
        super(L.t("Genetic Evolution info (8-14 islands)"), TYPE_PROJECT_BASED);
    }

    //------------------------------------------------------------------------
    
    @Override
    public JSONObject print() {
        JSONObject data = new JSONObject();

        GeneticInfo geneticInfo = project.getGeneticInfo();

        JSONArray items = new JSONArray();

        if(!geneticInfo.isGeneticBuild()) {
            items.put(new JSONObject().put("name", L.t("No data")).put("value", "No genetic evolution running"));

        } else {
            ArrayList<GeneticInfo.GeneticInfoIsland> islands = geneticInfo.getIslands();

            if(islands.size() < 8) {
                items.put(new JSONObject().put("name", L.t("No data")).put("value", "Less than 8 islands used"));
        
            } else {
                for(int i=8; i<Math.min(14, islands.size()); i++) {
                    items.put(new JSONObject()
                            .put("name", String.format("Island #%d", i+1))
                            .put("value", String.format("Generation: %d, Population: %d", islands.get(i).generation, islands.get(i).populationSize)));
                }
            }
        }

        data.put("items", items);
        data.put("type", DATA_TYPE_ROWS);
        
        return data;
    }

    //------------------------------------------------------------------------

    @Override
    public void addNextValue() {
    }   
}
