Layer managers organize layers and their panels.

The viewport handles two particular levels of zoom that may be accessed by double-clicking on a chart. The first double click zooms in and squares the time machine in the center of the screen, leaving a small margin with the screen borders. At this level of zoom, the scale boxes become visible.

A second double-click zooms in a bit further and the time machine occupies the whole screen. At this level of zoom, layer managers become visible.

Layer managers are usually found on the top-left and top-right corners of the screen. A time machine may have more than one timeline chart embedded and each timeline chart features a layer manager.

Layer managers are hidden when the zoom is partially out, to avoid blocking the view of the data in the time machine.

1. To move a layer manager to the opposite, top-right corner, left-click on the header and drag it away. Layer managers tend to self-arrange at either of these corners, so you may drop it somewhere next to its destination and let it find its place.

Left-click and drag to move a layer manager to a different corner. Use the wheel of the mouse to roll and scroll layer managers.

2. To roll a layer manager up or down, place the mouse pointer on top of the header and turn the wheel. When the layer manager cannot accommodate all layers in its current length, a scrolling bar appears on the right-hand side. To scroll through the layers, place the mouse pointer on top of any of the visible layers and scroll the wheel of the mouse.

3. To turn layers on and off, left-click on the layer.

  • When a layer is loading, the layer slot in the layers managers shows the progress with an orange dotted line on top of the layer’s name.

  • When a layer is on, the dotted line turns green.

  • When a layer is off, there is no line.

  • When the layer can’t load, the dotted line turns red.

Certain layers may feature a panel. Those which do, feature a panel button on the bottom-left corner of the layer slot in the manager.

Left-click and drag to move a layer manager to a different corner. Use the wheel of the mouse to roll and scroll layer managers.

4. To turn panels on and off, left-click on the panel button.

Panels tend to self organize on any of the four corners of the screen.

5. To move a panel to a different corner, left-click on the panel label, drag it somewhere near the preferred corner, and let it find its way to its destination.

Left-click and drag to move a panel to a different corner.

6. To minimize a panel left-click on the small triangle on the right-hand side of the label. To bring it back, left-click the triangle again.

The layer manager determines which layers will be visible on the corresponding timeline chart.

In other words, you use the layers manager node to configure which data products you wish to be made available for visualization purposes on the charts, in particular, on a specific timeline chart to which the layers manager node is attached to.

Adding a Layers Manager Node

To add a layers manager, select Add Layers Manager on the preferred timeline chart node menu.

Configuring the Layers Manager

Select Configure Layers Manager in the menu to access the configuration.

{
    "visibleLayers": 3,
    "panelLocation": {
        "upOrDown": "up",
        "leftOrRight": "left"
    },
    "label2FontSize": 12
}
  • visibleLayers keeps track of how many layers the managers is rolled to, that is, how many layers it is displaying.

  • panelLocation keeps track of the position of the panel relative to the four screen corners.

  • label2FontSize allows adjusting the font size of the second-order label of each layer, displaying the name of the exchange and market.

Click to learn more about layers

A layer represents a reference to a data product in the data storage node of the network hierarchy. Conceptually, it means that a certain data product, which exists in a certain location on the network, holds the data to be rendered on the charts.

To set up a layer, you need to establish a reference with the data product of your choice.

Adding a Layer Node

To add a layer, select Add Layer on the layer manager node menu.

Configuring the Layer

Select Configure Layer on the menu to access the configuration.

{
    "status":"on", 
    "showPanels":true
}
  • status may be on or off and refers to the layer being visible or not on the charts.

  • showPanels may be true or false; true shows the plotter panel that may be associated with the data product as per the plotter module definitions; false makes panels invisible.
