Could you give me the syntax for adding plotlines in the code behind? Currently, I'm using the following method but strangely this only works sometimes.

aspx:

<Axes>
<jqChart:LinearAxis Location="Bottom" ZoomEnabled="True" Name="MyXAxis">
</jqChart:LinearAxis>
</Axes>
<Axes>
<jqChart:LinearAxis Location="Left" Name="MyYAxis">
<PlotLines>
<jqChart:PlotLine>
</jqChart:PlotLine>
<jqChart:PlotLine>
</jqChart:PlotLine>
</PlotLines>
</jqChart:LinearAxis>
</Axes>

In the code behind (Page_Load):

JQChart.Web.UI.WebControls.LinearAxis Yaxis = Chart2.Axes(1) as JQChart.Web.UI.WebControls.LinearAxis;

Yaxis.PlotLines(0).StrokeStyle = "Red";
Yaxis.PlotLines(0).Value = 1.0;
Yaxis.PlotLines(1).StrokeStyle = "Blue";
Yaxis.PlotLines(1).Value = 0.6;

I defined the axes as below, but the plotlines only show on some of the graphs I display. Although, it seems to be consistant and based on the data being graphed. Sometimes the red plotline displays, sometimes the blue plotline displays, sometimes both, sometimes neither. But when I get out and get back into the same graph it does not change. So, if the graph only displayed the red plotline by getting out an back in it will still only display the red plotline.
I have run this in debug the the below code behind plotline statement are be executed.
