@stockprophet1,
Based on the link that you have shared, zoomEnabled property is set at stockchart level instead of chart level. Setting it at chart level (in RSI chart) should work fine in your case. Please find the code-snippet below.
var rsiDPS = calculateRSI(data);
stockChart.addTo("charts", {height: 100, zoomEnabled: true, axisY: [{minimum: 0, maximum: 100, stripLines:[{value:30}, {value: 70}]}],data: [{type: "line", name: "Relative Strength Index (RSI)", showInLegend: true, yValueFormatString: "00", dataPoints: rsiDPS}], legend: {horizontalAlign: "left"}});
