Generating speed chart.

[ss]

Dear All,
I would like to generate a speed chart. The problem my x-
axis will be on minute basis say in range of 10 hours so I have lots
of x-axis value. I do not mind to combine them and just show the start
and end time but all the in between points are to be plotted on the
map? Is there any solution on this?

A proper solution for this should be available soon enough. Stay tuned :)

In the meantime you can pass empty strings in the rows that should have no label, and change the label from the minutes to the minute-range in the other ones.
