plot vertical line

[manufacturer]

how will we plot a sigle or multiple lines in XY grph btwn two plot already aquired . I hv tried thru inserting a 3rd array and then choosing bar plot lines option ,with this i hv tried fill to baseline optin .

fill to bsln option work ok when it is selected as zero, inft,or -inft , but as soon as we choose a polt a fill replaces the lines

i hv trd all these but those thngs drw a line frm to to bottm or some otr thngs acualy wht a want is this

It's the same concept. You have to create the little vertical lines based on the Y values for your desired X locations, and then generate a plot that consists of 2 points and then just add it to the XY graph. See attached example (LabVIEW 8.2).

An alternative is to use plot images to just draw on the graph directly. This involves getting XY coordinates for the points you want to plot and then using the drwaing functions to draw a line. There's examples that ship with LabVIEW to show you how to draw on a graph. It's up to you to determine which method you think is easier.

sorry i could nt answr it due to the wrking hrs

thnks a lot it worked

actualy i was confused previously , how  could  we use two or more similar  X axis values

now it is clear

thnks again
