Hello!

I want to use QwtPlotPicker so the user will be able to see the correspondent Y and X axis values each time he puts the mouse over the graph - such as in the bode example. The problem is that I'm using a date-time x coordinate, and then when I use the QwtPlotPicker it shows the correspondent double value of the date-time, not the date-time itself.

How can I make the QwtPlotPicker show the date-time value correspondent to the X axis?

A secondary question also related to QwtPlotPicker is: how can I limit the decimals that is shown by it? In this app particularly, I want no decimals for the Y axis value.


Thanks,
