# Charts – Additional Features

## **How to Lock Objects on the Chart**

To prevent accidental changes to objects (drawing tools, indicators, etc.) on the chart, you can lock them using this feature:

- in the Workspace window, select ***Format*** menu > ***Move/Edit Objects using CTRL***.

When ***Move/Edit Objects using CTRL*** is checked, chart objects can only be moved or edited by holding down the CTRL key while making changes.

To unlock objects, uncheck ***Move/Edit Objects using CTRL***.

## **Cross and synchronization across multiple charts**

In Overcharts, you can display the Cross (a horizontal and vertical line) at the mouse pointer's position on one or more charts simultaneously.

From the Workspace window:

- select ***View*** > ***Cross*** > and choose one of the following options:
  - **Single Inner Window**: displays the cross only in the inner window where the mouse pointer is located.
  - **Multiple Inner Windows (Column)**: displays the cross in the inner window where the mouse pointer is located and extends the vertical line to other inner windows in the same column.
  - **Time & Price (Column)**: displays the cross in the inner window where the mouse pointer is located and in all inner windows within the same column.
  - **Time & Price (Instrument)**: displays the cross in the inner window where the mouse pointer is located and in all inner windows within the same chart window.
  - **Time & Price (Chart-Group)**: displays the cross in the inner window where the mouse pointer is located and in all inner windows within the same chart group.

Note: Instead of the menu, you can use the corresponding button in the 'Chart' Toolbar.

## **Suspend/Resume Real-Time in Chart**

With each chart, you can suspend and later resume the real-time data update. This allows you to closely examine a specific state without live updates changing what you're reviewing. When you're finished analyzing, simply resume updates to go back to real-time data.

To **Suspend** real-time updates:

- At the top right of the chart window, click **Real Time & Historical Data** and select **Suspend Real-Time**.

To **Resume** real-time updates:

- At the top right of the chart window, click **Real Time & Historical Data** and select **Resume Real-Time**.
