How can i use Numeric to plot gragh ?

How can i display the numeric output from the string to plot onto the gragh ? As for now, once i run the VI, there won't be any output shown on the graph.

Hi falcoz,

currently its only one point. You can see this point if you change the plotstyle.

Right click on the Reset input and select "Create Constant". If it creates a True constant, change it to false.

Since I don't see a while loop anywhere, you will only get a single point. Your point style is probably set to none so you would not see anything. Change that.

Thanks alot. I have change the plotstyle and awhile loop. I can manually draw a graph now but if i would like to simulate a voltage and current value into graph, how can i do it ? By inserting array or ? If is insert array, where do i place it ?

You can just build array

thanks muks, but how can i combine the array with my VI as my input is a string and the output is actually separated out into voltage and current.

I am not getting it. Can you tell me what is your input and expected output?

As you can see from my attached VI in the earlier post, in the string box (eg. 4.23 V 4193uA ), it is actually separated into Voltage box and Current box. My idea is how can i create a string array to simulate onto the voltage and current graph.

You mean to say you will be continously getting values like (4v3a5v2a etc)
