How do I make line labeling styling that can adjust base on line length

[jeff.wangD95HG]

I basically want to create a general line label style that looks like the picture above. but I want it to adjust the spread distance base on percentage of the length of the line instead of a set value.

currently I just anchor it to end or beginning and set a specific x offset value

since there is an option to reference to general segment length ground I am wondering if there is a way to reference to it and do some calculation to it so that it automatically adjust base on the line length

I'm not sure I'm understanding ....

Why not anchor to the middle?

Or are you looking to label one line segment with 3 values that are a percentage of the overall length and have each one centered in its portion of the segment?

Use an expression that does the math for you. The math would set the text height to be the size that shows up or really tiny so it doesn't show up. Then add a component for each distance you want to be labeled.

I agree with @MMcCall402. More information would be helpful.

You can create expressions that are percentages of the line length and use those for X Offset values.

You would need an expression for each location you are interested in.

(You do not need expressions for Start, End, or Center.)

EDIT:
In your style, you will need a text component for each location.
Thanks to @MMcCall402  

Alternatively - You can use will need a separate style for each location.
This is a good time to use child styles.

Good Luck!

label one line segment with 3 value. value 1 at approximately 15% of the length of the line, value 2 at approximate 50% (half way point), and value 3 at 85% of the length of the line

[jeff.wangD95HG]

this is exactly what I was looking for.

I am not sure how to access that component of the UI nor do I know the key words to search to gain information

[ChrisRS]

I'm glad to help. 

Note: I edited the original Message. You can use multiple components in one style.

can you give me some quick screen shots on how to access the calculation menu for it to automatically fill in?

The expression calculations are not fully automatic.

Start in TOOLSPACE >>
Settings Tab >> Position to the proper branch

Right-click Expressions and select New...

The New Expression form will be blank.

Fill in the Name and Description field manually.

(The Name cannot be changed so avoid spelling errors.)

If is best to choose properties and functions using the buttons and drop down lists. 

Click OK to save.

I hope this answered your question.

For the placement of those expression values you could add 3 line components to the label style, anchor them from 'start' to 'end' and then specify a % value for their length.  Anchor the 3 expression values to their end points and then set the line components visibility to 'false'.

ok thanks this is an easy solution as well.

Great idea. I edited the original message to reflect this as the primary approach.
