reading from an array

[altenbach]

Yes, you could use an image. for the graph. You could first plot the image and then the dots over it.

You need to place a 2D picture and use picture tools to compose the graph. Have a look at some of the examples (e.g. "xy multiplot" or "waveform and xy plots").

To place an image in the back of the xy graph, you can use the plot images tools. Have a look at the "plot images" example).

Then show us your code again....

I have managed to do that!

two more remaining problems that i cant find solutions

first after ploting the points and displaying the values in the control box i want to reset everything how to do that?

and second i want to plot the spectrum using matlab code into labview how to do that?

if you help me in these two im done 😄

Create an event for the reset button and set the array containing the points back to zero lenght. What elese should the reset button do?

What is so special about matlab code? What does it do?

You can translate the matlab code into plain LabVIEW, probably with little effort. (preferred)

If you have mathscript, you can use matlab-like syntax without the need of having matlab.

If you have matlab installed, you can also use the matlab script node.

the code is very simple im just going to plot the spectrum,

im going to try your suggestions and see which one works. if you have better idea for the following code please let me know 🙂

% Input Parameters

    %peak wavelength

    lamb1=468;

    lamb2=570;

    lamb3=689;

    lamb4=700;

    lamb5=0;

    %intensity

    i1=0.62;

    i2=0.55;

    i3=0.52;

    i4=0.5;

    i5=0;

    light=gausslight(lamb1,i1,lamb2,i2,lamb3,i3,lamb4,i4,lamb5,i5);

plot(380:5:780,light,'b','linewidth',2)

grid on;

title('Light Spectra')

xlabel('Wavelength (nm)');

ylabel('Intensity')

the reset button should clear the graphs too.. 😄
