There are two types of price bubbles/labels that appear on the y-axis. One is the current price of the security and the others indicate the current value of studies (overlays on the main chart area and study values within study panels). Either or both can be removed if desired.

Case 1 -- Remove Price Bubble/Label For Studies

This will turn off price labels for all panels:

stxx.preferences.labels=false;

You can also turn off price labels for a specific panel:

stxx.panel[panelName].yAxis.drawPriceLabels=false;

Case 2 -- Remove the 'Current Price' Bubble/Label

The current price label is either green or red depending on the value of the security relative to the prior bar. It can be disabled with the following setting:

stxx.chart.panel.yAxis.drawCurrentPriceLabel=false;
