How to connect bias points to central line?

Jericson — Sun, 11 Jun 2023 11:28:51 GMT

Hello,

I am working on some error analysis and have been asked to represent our biases in a plot graph. I have the biases plotted but was also asked about connecting each point back to "0 bias". I know I could do it with HLine for each individual point but was wondering if there was a way to accomplish the same feat using a script for all points rather than one by one. I am using JMP 16. I am also attaching a mockup version of the data for reference.

Thanks you very much.

You can most likely add bar chart which is being styled as Needle. This way you won't need scripting at all

and then you can add 0 as reference line if you want (and style the visuals as you want)

Hello,

Thank you so much. Glad to see the answer was even simpler than I expected. This does exactly what I was trying to do with much less work than I was expecting.

There might be some problems if there are multiple values for same concentration. In that case V Line might be the easiest option. Below is one option which should work

Pen Size(1);
For Each({val, idx}, :Concentration << Get Values,
	V Line(val, 0, :Bias[idx]);
);

Edit: In some cases it might be enough to change the bar plots summary statistic to min/max. In some cases you might have to add two bar charts, one for Min and one for Max
