Nope. Emoji on the chart are a fun addition and available for both Kindara Basic and Kindara Premium users. To have an emoji on your chart instead of a gray dot, make sure the emoji is entered at the beginning or at the end of the custom data field. If the emoji is somewhere in the middle, your entry will still appear as a dot.
If you have an emoji in a custom data field that is not appearing in your chart or still appears as a gray dot, please email us at firstname.lastname@example.org with the emoji that is in your Custom Data Field to let us know that your emoji isn't recognized.
