How do I accentuate the zero line on my chart?

Highlight the zero line to help the reader distinguish between positive and negative values.

Go from this:

To this:

To highlight the zero line in a chart:

  • Go to Customize > Basic > Annotations

  • Under Lines click +

  • The plot area is highlighted. Click anywhere to start your line.

  • Click and drag the white circle with a black outline to set the length of your line

  • Drag the line to the 0 line

  • Under Size select a value, e.g. 2 or 3, to set the line width

To highlight the zero line in a chart:

If your line is the full length of your chart, you can also use a plot line instead of an annotation.

  • Go to Customize > Advanced > Y axis
  • On Plot Lines, click +
  • Under Plot Lines 1 you can change the color, dash style, value, line width and z Index


Hi Kerry! Nice to see you on here, finally!

I definitely prefer this solution, as it allows one to be absolutely sure about the plot line covering exactly the value one desires (in this case x=0)

The Z index is of course important, because artifacts like the grid line showing here in white:

And we might want to make that Z index a default behavior. But I can’t say for sure before we get to investigating if there are any trade-offs.


to follow up on this, is it possible to have my tick marks on my zero (0) line?

hopefully the screenshot provides further explanation

I am not aware of any way of doing this. It might be possible by defining an extra axis and using that as your would-be plot line.

On the other hand, you can add gridlines to the horizontal axis, although your lines will cover the entire vertical span at that point:

You can set this by going to X Axis [1], and adjusting the “Grid line width”.

You could try changing the Top position of your x-axis to a percentage (if you use a number instead of a percentage it seems to change positions when responsive).

Then, if you want your labels to stay at the bottom, you could change the Y position of those.


thank you @KerryHolm I’ll give that a go :grinning:

struggling with offsetting the y position of my labels. I’ve tried to toggle “reserve space” and this sometimes addresses the issue, but a short-term fix is to manually set the height of my embed frame to include the labels

Hi Chris,

The labels moved with the x-axis when I tried @KerryHolm’s suggestion to change the top position of the x-axis , as shown here:

Seems like your xaxis line moved but the labels remained in the original position.

Hi Kerry,

Tried to create this but got stuck.

Should I add a line annotation first, then work in the advanced menu?

Thanks in advance!

Hey Mark,

That’s how I’ve done it in the past.

Added the annotation line in basic, then edit in the Advanced menu.

Hi Mark,

I am able to do it by following the steps that I mentioned above. I like doing this this way because you don’t have to use the annotations to make it work.

What isn’t working for you?

I figured it out, thanks :slight_smile:
