Simple plot/graph question

[iainhp]

I inherited the attached multi plot - originator is not here anymore. It's Monday and my brain is not functioning yet. Can someone tell me how to reduce the number of plots to 4 from the existing 9. I have done it before but, like I said, it's Monday. Thanks.

Reduce the number of plots in the legend...

Thanks, but that doesn't seem to do it.

To clarify the question - the chart I am referring to is a stacked plot. There is an example of it in the examples section under general/graphs/charts.llb. Select charts.vi . In the center of the panel is a strip chart example labelled 2 plots stacked, 1 pt/update. How do you increase (or decrease) the number of stacked plots to 3? Resizing plot legend doesn't do it, unless there is some magical second step that I haven't figured out.

Charts take several datatypes. I believe the VI you are looking at is
using a cluster of scalars. Grow the bundler to add another element to
the cluster and the chart will automatically add another stacked plot
area. If the datatype is 2D, then the plot legend controls how many
stacks there are.

Attached is you VI that I modified so that a bundle of data is sent to the chart. This automatically dropped the stacked charts down to two--the number of data bundled.

Thanks - that does the trick. Had tried this but the bundler was in a sub vi and didn't seem to change anything when re-sized.

OK - new issue with the strip chart. I'm getting multiple lines at the right hand edge of the chart. These lines tend to follow the main plot and, strangely, seem to increase in number if if I move the mouse (more appear the faster I move the mouse). I have attached a screen shot to illustrate. Is this a feature I need to turn off or something else?

It looks like you may have a corrupted VI. Try changing the order the signals are bundled. If the error follows the signal, the problem might be with the signal. You can also place a new chart and wire the signal to it. If this works fine, make the new chart look as much like the old one as possible and delete the old chart. VIs are complicated and sometimes they become corrupted.
