Adding multiple value axis to a Stock Charts panel

In Stock chart, each StockPanel is an instance of AmSerialChart. So you can add ValueAxis objects to it like you would normally add to a regular chart.

Each StockGraph is an instance os AmGraph so it has valueAxis property.

So adding multiple value axes to a stock panel is just like adding them to a regular basic serial chart. I.e.:

// adding stock panel
var stockPanel1 = new AmCharts.StockPanel();
stockPanel1.title = "Value";

// add value axes
var valueAxis1 = new AmCharts.ValueAxis();
stockPanel1.addValueAxis(valueAxis1);

var valueAxis2 = new AmCharts.ValueAxis();
valueAxis2.position = "right";
stockPanel1.addValueAxis(valueAxis2);

// graph #1
var graph1 = new AmCharts.StockGraph();
graph1.valueField = "value";
graph1.lineThickness = 3;
graph1.lineColor = "#00cc00";
graph1.useDataSetColors = false;
stockPanel1.addStockGraph(graph1);

// graph #2
var graph2 = new AmCharts.StockGraph();
graph2.valueField = "volume";
graph2.type = "column";
graph2.showBalloon = false;
graph2.fillAlphas = 0.5;
graph2.valueAxis = valueAxis2;
stockPanel1.addStockGraph(graph2);

// set panels to the chart
chart.panels = [stockPanel1];

That’s it. Now you have two graphs, one attached to left value axis, the other to the right one.

Here’s a working demo.
