```
    Called after transmitting actual changes, allows batch processing of changes.
  - onHeatmapTimeLeft
```
void onHeatmapTimeLeft(long heatmapTimeLeft)
```

    Parameters:
    
    heatmapTimeLeft - new time in nanoseconds
  - onHeatmapActiveTimeWidth
```
void onHeatmapActiveTimeWidth(long heatmapActiveTimeWidth)
```
    Width of the heatmap area corresponding to data (in nanoseconds) changed.
    
    Parameters:
    
    heatmapActiveTimeWidth - new width in nanoseconds
  - onHeatmapFullTimeWidth

    Parameters:
    
    heatmapActiveTimeWidth - new width in nanoseconds
  - onHeatmapPriceBottom
```
void onHeatmapPriceBottom(long heatmapPriceBottom)
```
    Lowest price displayed on heatmap changed
    
    Parameters:
    
    heatmapPriceBottom - new lowest price as a number of level (multiply by InstrumentInfo.pips to get human-readable price).
  - onHeatmapPriceHeight
```
void onHeatmapPriceHeight(long heatmapPriceHeight)
```
    Number of levels displayed on heatmap changed
    
    Parameters:
    
    heatmapPriceHeight - new number of levels
  - onHeatmapPixelsLeft
```
void onHeatmapPixelsLeft(int heatmapPixelsLeft)
```
    Position of left edge of heatmap on inside the window changed
    
    Parameters:
    
    heatmapPixelsLeft - new x coordinate in pixels
  - onHeatmapActivePixelsWidth
```
void onHeatmapActivePixelsWidth(int heatmapActivePixelsWidth)
```
    Width of the heatmap area corresponding to data (in pixels) changed.
    
    Parameters:
    
    heatmapActivePixelsWidth -
  - onHeatmapFullPixelsWidth
```
void onHeatmapFullPixelsWidth(int heatmapFullPixelsWidth)
```
    Width of the heatmap area (including the part containing no data, in pixels) changed.
    
    Parameters:
    
    heatmapFullPixelsWidth - new width in pixels
  - onHeatmapPixelsBottom
```
void onHeatmapPixelsBottom(int heatmapPixelsBottom)
```
    Position of bottom edge of heatmap on inside the window changed. Y coordinate increases when going up (same direction as price increase).
    
    Parameters:
    
    heatmapPixelsBottom - new y coordinate in pixels.
  - onHeatmapPixelsHeight
```
void onHeatmapPixelsHeight(int heatmapPixelsHeight)
```
    Height of the area representing the heatmap (in pixels) changed
    
    Parameters:
    
    heatmapPixelsHeight - new heatmap height in pixels
  - onRightOfTimelineLeft
```
void onRightOfTimelineLeft(int rightOfTimelineLeft)
```
    X coordinate of the timeline has changed (in pixels). Note, that in drag mode when timeline is not visible it's considered to be in the leftmost pixel of heatmap.
    
    Parameters:
    
    rightOfTimelineLeft - new x coordinate of timeline in pixels
  - onRightOfTimelineWidth
```
void onRightOfTimelineWidth(int rightOfTimelineWidth)
