Display Temperature and Time on a graph in LabView-Code

[labviewsdaughter]

I want a LabView program who calculates the temperature at which a  flow of water is heated with the help of a resistance. The program includes:

• entering the necessary data (flow of water and power of resistance) through elements on the front panel or by reading them from a file
• the possibility of changing the flow of water and the power of resistance values from the front panel and to display the results on a graph Temperature=f(time)
• the possibility to save the dates in a text file

Thank you! 💛

Simple answer: then you need to create such a program!

The generic answer for your rather generic question is:

• we will not do your homework
• we will be happy to help you with your code - as soon as you attach your code!

Hi daughter,

no need to start a new thread for the very same question, especially when you already got an answer!

Hello! This is the code.

Hello daughter,

could you please downconvert your VI to LV2019 (File->Save for previous) and attach again?

[labviewsdaughter]

19 VI and thank you again!

All this is already found in your VI, so what is the actual question/problem?

Recommendations:

• NEVER delete the label from frontpanel elements! You may hide the label on the frontpanel, but should not do so in the block diagram!
• When converting from °C to K you usually don't add "283". LabVIEW may do this for you by using two ConvertUnit functions…
• You should learn to create plots for your XY graph. There is a nice example VI in the example finder, which explains the differences for chart and graphs!
