Re : Plotting Discrete Histogram

[ade77]

I tried to plot the contrast information of an image using the IMAQ histogram., But the output of this vi does not have a IMAQ display associated with it.  Even when I tried to use the built in LabVIEW graphs to display the histogram, it gives a continous plot.

Is there any VI I can use to display a discrete histotram plot as shown in the attached picture.

Thank you.

Instead of IMAQ histogram, use IMAQ histograph.vi (vision and motion > image processing > analysis > ...), and connect a waveform graph to the histogram graph output. Then choose a bar plot style.

Thank you Chilly. I did what you suggested, however, I can not change the waveform plot to bar plot.

There is no option to change it to bar plot.

I have attached the VI .

Thanks.

Right-clic on the graph > Visible items > plot legend 

then clic on legend > bar plots... 🙂

Thank you very much Chilly.
