Dojox Charting. Cannot change indicator line style of MouseIndicator - dojo

Question

I'm trying to create chart using Dojox charting. I created plot and added Series.
this.addPlot("st", {type: Lines, markers: false, tension:"X"});
this.addSeries("Series A",
[{x:0, y:0}, {x:5, y:10},
{x:10, y:12}, {x:15, y:14},
{x:20, y:15}, {x:25, y:16},
{x:30, y:18}],
{plot: "st"});
Then I added MouseIndicator
new MouseIndicator (this, "st",
{series: "Series A",
labels: false,
mouseOver: true,
lineStroke: { color: "blue" }
});
So it has added indicator but with default colors.
Tried to change indicator with lineStroke, lineOutline or lineShadow. Nothing changed.
According to API docs it should change the line style^ http://bill.dojotoolkit.org/api/1.9/dojox/charting/action2d/MouseIndicator
Does anybody knows how to change MouseIndicator line style?

Here is my Hack of a solution.
Using dojo/aspect (http://dojotoolkit.org/reference-guide/1.10/dojo/aspect.html) to listen on the "_onMouseSingle" of the MouseIndicator object, and after this event occurs, change the marker and line stroke colors:
var mouseHoverIndicator = new MouseIndicator (this, "st",{
series: "Series A",
labels: false,
mouseOver: true,
lineStroke: { color: "blue" }
});
aspect.after(mouseHoverIndicator, "_onMouseSingle", function (value) {
var plot = mouseHoverIndicator.chart.getPlot(mouseHoverIndicator._uName);
plot.opt.markerStroke= {color:"blue"};
plot.opt.lineStroke= {color:"blue"};
plot.dirty = true;
mouseHoverIndicator.chart.render();
});
