generate xy-graph

[Simon790]

Hello

I have created a VI which polls a directory. If a certain bmp is stored by another application into this directory my VI loads this bmp and transforms it into an array from which it calculates min, max and mean of the RGB Values. It also controls the intensity of a light source with an analog output of a DAQ-card. At the same time its reading an analog input which representates the light intensity measured by a lux-sensor. Now i want to generate a xy-graph which draws the three different RGB values in dependency of the measured light intensity (photons). Every time a new bmp is analysed the results should be attached to the graph. I tried several methods to draw a graph but i always failed.

can somebody help me? 

Thanks

Simon

Hello Simon,

I do not really understabd how you want to generate the graph with the differents RGB value.
    Do you want to use the min, the max and the mean of each RGB values
    How do you want to use the dependency.

And did you try with an intensity graph?

Best regards

I think a graph with one mean value (red, green or blue) in the dependency of the measured light intensity at the moment the picture is processed would do it for the beginning

Yes i tried also with an intensity graph, but without success!

thx simon
