Ok, it is almost done. I got everything working except when assigning different plot to different y-axis scale in the property of the graph. It wouldnt let me. When I assign the duplitcated scale to plot 2, it changed back to original scale automatically. Somehow it wouldn't let me assign the duplicate scale to different plot. Please help again. Thanks and I appreciate both of your help. :worship:

Hi guys, I'm trying to display two plots within one xy graph. I got that to work. But I want both plots to have different Y Axis scale (ex. plot 1 with a 5db scale and plot 2 with a 10db scale). I know that i can do this by displaying each plot with its own xy graph, but that's not what i want. I want both to be in the same xy graph and have different scale. Please help. Another problem that i have. Is it possible to put a marker at a point in a xy graph? if yes, how? thanks.

Will the version of LabView that i'm using effect it in anyway? I'm using LabView 8 Professional. I search through the forum and i came across one that said that this problem is a Front Panel printing bug. It will only print in gray scale. Someone please help me. Thanks in advance.

I did exactly that and it still not working. I can change the background color to any color but it still print as gray background color.Please help.

Ok thank you guys. Problem solve. THere is still one more printing problem that i have. When i tried to print the front panel, i get a gray background. I tried to change the front panel background to white from Tools>>Options to white. I noticed that that will only effect new VIs. I create a new VI and the background of the front panel is white. But when i tried to print it, i still get the same gray background. Is there anyways to solve this problem? Thanks in advance.

Hi everyone, I am working on a company's application that display a filter on the XY GRAPH. When I print the XY GRAPH in GRAYSCALE, the background of the graph is black. I want to change the background of the graph to WHITE but there isn't any option provided by labview in the property of the xy graph. Is there anyway at all to change the background of the xy graph on the plot section. Please help fast.
