I don't follow your requst.

Please post an image or code that illustrates your challenge.

The Picture Control thread contains links to many picture realted examples.

Depending on which version of LabVIEW you are using, the Annotations may also serve your needs.

I am attaching the VI and also the exported jepg  image.Acctually the prog generates the bmp image but as NI forum doesnt allow bmp file to upload.
In the VI I am reading two temperatures one from Dbus to get the sensor temperature and the other is thermocouple temp from the center of oven.The exported image is generated automatically at the end of the run.You can see that in block diagram of attached VI below the while loop

I need the user defined text to be displayed on to the exported image.

I will forget I looked at your code.

Two ideas.

Use the plot>>>name property to set the plot names.

or

Read the final file, insert text in picture, save to file. There should be examples in the pciture thread I previously posted or in LabVIEW's built in help.

I hope that helps,

Ben
