The intensity graph may not be plotting if you have selected the wrong indicator graph type in the Block Diagram. To fix this, follow these steps:
- From the Front Panel Right-Click to open the Controls Palette and Select Graph >> Intensity Graph and place the intensity graph on the Front Panel.
- Wire the Intensity Graph as the output of your 2D array of values (in this example the TFA Configure Coefficients Indicator VI is used).
- Right-Click the Intensity Graph icon in the Block Diagram and Select Create >> Reference. Place the reference on the Block Diagram and wire as the reference of the indicator (in this example the TFA Configure Coefficients Indicator VI is used).
If these steps do not work, the VI may be corrupted. Copy all content in the Block Diagram and Paste in a new VI window. Save and complete steps 1-3 from this new VI.
