Hello. I often add data labels by going to Plot Properties - Enable Labels at Specified Indices. This works great. But I am wondering why I can't add symbols to those specified indices at the same time. I usually add a red vertical line as a symbol. I am aware of the leader lines, but I want the vertical lines to actually touch the data point to lessen confusion, which I can't seem to do with the leader lines, they are always too far offset.

So, my question(s) are:

Is there a way to add symbols along with the data labels at specified indices?
Is there a way to get the leader lines to actually touch the data points?

TIA.

Hi,

If you simply want to add a vertical line attaching data points. you can use the settings below.

Hmm, that's a neat trick, thanks. Except I can't then also have the X axis point as the data label.

I'm looking for the following, where the carat is the peak maximum.

The way such markers and labels are done in Origin itself typically involves creating a second dataset consisting of the "peak" X & Y values.

A plot of this dataset is then added to the graph a scatter plot.

You can then customize the symbol shape and color to suit your needs and even enable labels for this plot. This way you have a lot more control.

I hope this helps.



Thanks,
