Only the first series in Microsoft .NET stacked column chart control displays tooltip correctly

Question

The following tooltip has been added to the stacked column chart series:

    foreach (Series s in ch.Series)
    {
        s.ToolTip = "#VALX: #SERIESNAME - #VALY";
    }

However, only the lowest stacked series in every column displays proper value for #VALX , ex:

Sales: From $0 to $1000 - 6

All other series above display 0 instead:

0: From $1001 to $10,000 - 19
0: From $10001 to $20,000 - 4

What am I doint wrong?

对于任何偶然发现的人，请尝试 #AXISLABEL 而不是 #VALX
