Hi @jchau,
Yes, it looks impossible to achieve the requirement with Fill="true". The Fill of the upper line is in priority...
My next thought is to use an AreaSeries. Though, there is a quirky behavior - it overlaps with the Axes lines.
Example
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
Store s = this.Chart1.GetStore();
s.DataSource = new object[]
{
new
{
x = 0,
y1 = 25,
y2 = 50
},
new
{
x = 50,
y1 = 35,
y2 = 65
},
new
{
x = 100,
y1 = 25,
y2 = 50
}
};
}
}
</script>

<form runat="server">
<ext:ResourceManager runat="server" />
<ext:Chart

</Fields>
</ext:Model>
</Model>
</ext:Store>
</Store>
<Axes>
<ext:NumericAxis Title="X" Fields="x" Position="Bottom" />
<ext:NumericAxis Title="Y" Fields="y1,y2" Position="Left" Minimum="0" />
</Axes>
<Series>
<ext:LineSeries Titles="Line 1" XField="x" YField="y1" />
<ext:LineSeries Titles="Line 2" XField="x" YField="y2" Fill="true" />
<ext:AreaSeries XField="x" YField="y1">
<Renderer Handler="attributes.fill = 'white'; return attributes;" />
</ext:AreaSeries>
</Series>
</ext:Chart>
</form>
</body>
</html>
Maybe, you could try to use an AreaSeries instend of LineSeries at all?
