Change the x-axis min and max values for QT GUI time sink block

GNU Radio

Hi all,
In WX GUI time sink when we roll the mouse over the plot we can change
the range of y-axis and x-axis but in QT GUI time sink it is not
changing in this way.We can set the range for y-axis in block
parameters but how can I change the x-axis min and max values for QT
GUI time sink block during run time??
regards,
Ali

Hey Ali,

you can just select the portion you want to see with the mouse.

Yes i know that but it is used for zooming…actually my sink is not
showing the complete waveform as the time period of waveform is
greater than the max value on time axis,so i want to know how can i
expand my time axis??

You can set the number of points to show in the setup dialog.

Use the menu. Middle-click (or whatever the equivalent of a middle mouse
click, “Button3”, is on your machine) to get access to the menu options.
Then you can set the “Number of Points” to display.
