Overlay target line on a histogram

SaraGo — Sun, 11 Jun 2023 11:19:44 GMT

How can I draw an histogram and overlay a line on it? (i.e. a line showing the target/minimum requirement for the histogram's columns) Please see the picture to understand what is the result I'd like to get.

The line doesn't necessarily have a constant value, but plots the values recorded in a different column of my table. Referring to the example in the picture: the target sales might differ day by day.

I'd prefer an interactive explanation rather than a scripting answer. Thank you!

Hi @SaraGo ,

With any graph in JMP, you can double click on either the horizontal or vertical axis and then in the Reference Lines panel box, you can edit the corresponding boxes to get your reference line that you want.

Hope this helps!,

Since the line may not have a constant value, I created a simple example where the target changes. I have attached that file. I can create a chart that looks like this:

In Graph Builder, drag Day to the X-axis. Drag Daily Sales and Sales Target to the Y-axis. Change the graphing element to the bar chart. Change the Bar Style to Single.

Another option is to go with a more continuous line for the Sales Target.

You can get that as well, but has a few more steps.

Drag Day to the X-axis. Drag Daily Sales and Sales Target to the Y-axis. Change the graphing element to the Bar Chart. Click the Variables triangle and clear the checkmark from the Sales Target.

Hold the Shift key down and click the Line graphing element. Under the Line properties, click the Variables triangle and uncheck the Daily Sales variable.

Even if neither of these are what you want, I think the steps will show you some different ways to work with Graph Builder to get the picture that you want.
