How can I change the thickness of a line in a Picture object?

[Jean-Michel D]

I want to change the thickness of the line in a Polar Plot. I can easy change the color but not the thickness of the line displaying the data. I have seen that the 'polar Plot' function use the 'Draw Line' function of the 'Picture Functions'. Do you have a solution? Thanks in advance.

Hi Jean-Michel,

If you dig down a few levels from the top-level Polar Plot VI, you will find vi.lib\picture\polarplt.llb\Plot Polar Data.vi. Inside this VI is a VI called "Draw Multiple Lines.vi", which has a "pen" input. This input is currently not wired, so it defaults to a line style of "Solid", and a width of "1". If you take this input and propogate it all the way up to the top-level Polar Plot VI, you can now specify the line width and style of your polar plot.

I have submitted this as a suggestion, so perhaps we will see it in a future version of LabVIEW.

LV7.0 version of Draw Line has the line width as an input. In LV6.1 you must edit this VI because the creator decided to code the width as a constant. This constant could be changed to a control and added to the connector pane. Then you could use your custom version of Draw Line to modify the version of the Polar Plot VI
