Hi,
I am using the API reference and this code snippet as examples for adding crosshairs to my XYPlot which contains a variable number of LineSeries. So far it has been working, but I am running into some cases where one LineSeries is shorter than the rest and crosshairs won't show up for X values that go beyond the shortest lines' X values.

Here's an example. The top line is shorter and the Crosshairs only show up until the last X value of the shorter line. I want to be able to show Crosshairs for all values up until the end of the graph (the longest line).

Is this possible?
(Even if I just take the example code and just make one line longer than the other by making one data array longer, I run into this same behavior.)

Help would be greatly appreciated!
