Currently I do not know of a way to hide certain values from showing in the data box. Even if the “visible” box is unchecked from indicator options, only the line from the chart is removed, but not the value from the data box.
Based on your documentation, “displayOnly?: boolean
Specifies if the plot should be displayed only on the chart, but do not show it in Data Box” (link below)
Does setting this to true currently do anything? In the built in RSI indicator the middle, overbought, and oversold are set to displayOnly: true, yet they still show in the data box. (image below)
I am requesting this feature be added to the data box, or if it is possible could you please tell me how this is done.
