Labview graphs and data displayed on them

I am using graphs to display measured values read from an NI ELVIS board. the problem is that the graphs only display data read between 0 and 10 milli seconds . i have tried changing the scale (time axis) from auto to custom by unchecking the auto-scale box and using my own ranges. the scale does get streched but ony data between 0 and 10 milli seconds is displayed on the graph. how do i show data from a period longer than 10ms e.g displaying data from a 10 minute log on the LabView?

Sounds like you should really be using a chart and not a graph. A chart has a settable history and a graph does not unless you write the program to retain older values.

I have tried using charts but the same thing still happens.

 

what i am actually doing with my program is reading data using the DAQmx from an NI ELVIS board and then store the data as an LVM file using the "Write LabVIEW Measurment File" express vi. I then use the "Read LabVIEW Measurement file" express vi to retrieve the logged data.

 

Is there another way of getting back the logged data in a graphical format because using the graphs or charts does not seem to be working very well?
