HOW TO GET THE PEAK VALUE OF TEMPERATURE FROM GRAPH

[sridhar..reddy]

I am new to Labview,I want to get the peak value of temperature and i am also getting the graph and i had taken an indicator to represent the values of temperaure,

Then the problem is,I am not able to get exact peak value from the graph.Can any body help me.

You have an array with the graph data?  Use Array Max & Min to find the maximum value and the index of that peak.

Thank You for the quick reply sir.

My intension is to capture that peak vaue to excel sheet .

I am trying to compare the previous value with the present value , Because the values of the temperature are varying regularly,so i am not able to compare the values as i mentioned((previous value and present value)), I thought that if i can move the present value into the register then it will become a previous value to the next coming value so that i can compare them ,but i dont know hw to move the values in to the registers.

Suggest me to capture the only peak value to the excel sheet or else let me know that how can i move a value ((integer)) to a register to store.

Something like this?

may i have the VI FILE which you mentioned in the image above.

Can't you just make it on your own?  The only remotely difficult part is the feedback node.  There are a couple of right-click menu options to move the initializer out to the loop and another to reverse the direction of the feedback node.

If you do not know how to rebuilt that simple VI, then I highly recommend you go through some of the tutorials that are available.

This is not very likely to happen. You have to understand that this forum is available to get help, not solutions.

If your time schedule is too short for the experience you bring to the project, there are only two ways to solve it:

a) talk to your manager to get more time

b) use all spare time you can collect until the dead line and work hard on gaining LV knowledge

I assume we can replace "manager" with "teacher" in bullet a)......

PS: You really got valuable information and hints here. Use them. Try things out and let us know if there is something with those trials (that is: post what you are trying).

[sridhar..reddy]

what u said is correct sir,

how can i get that arrow in that image ,i stuckup for that acually.

need help for that sir.

[Norbert_B]

Your image is very small, so i have to guess:

that is a feedback node. Once you place it , you have to "Change Direction" to get the arrow from right-to-left to point left-to-right as obviously in your image.....
