Charts can (potentially) use enormous amounts of memory, because all of the historical data with regards to prices and indicators is preserved. For that reason, in JBT, you can show charts only one at a time. That is, the chart becomes available after you run a backtest for a given strategy A. If subsequently you run a backtest for strategy B, the chart for B becomes available, and the chart for A is no longer in memory.
