Data Point Size, Graph Drawing

[zman515]

I have two questions. I am running a program that is reading in data from a serial port and plotting it in real time.

First, is there any way to increase the size of each data point on the screen to make it easier to read.

and

is there anyway to stick permanent shapes on the plot so it looks like this?

Thanks in advance

Right click on the plot, select Visible Items > Plot Legend

Right Click on the appropriate Plot Legend with the finger icon. Select Point Style and choose a bigger dot. Set interpolation to get rid of the lines and increase the line width to make the dots even bigger.

is there anyway to stick permanent shapes on the plot so it looks like this?

I've done something similar using a picture control behind an X-Y graph with a transparent background. The picture control, which I think I found in the Labview Examples, contains the concentric rings and radial lines. Putting a transparent indicator on top of another front-panel object is a no-no from a performance standpoint, but I figured it was better than creating the circles as plots within the XY graph and it doesn't seem to be too bad.

Yes. In LV 8.0 I believe three properties were added to the graph which allowed you to insert a picture 1) behind all display elemnents (grids and plotted data), 2) Between the grid lines and plotted data, and 3) in front of both grids and plotted data. I don't have LV 8 installed on any of my machines, but I'm pretty certain it made it into the release. The properties (or maybe they are invoke node methods) take a picture string as their data, just like you would wire to the picture control. Hopefully this would save you from using Gary's solution.
