Read MoreAdaptive Frequency Hopping
Bluetooth communication networks are prone to signal interferences in environments where other wireless networks coexist. The problem is aggravated when they use the same frequency bands. Bluetooth technology and IEEE 802.11 networks, like Wireless LANs (WLANs) and WiFi, operate in the same unlicensed 2.4 GHz ISM (Industrial, Scientific, and Medical) radio band. In order to reduce the impact of these interferences, Adaptive Frequency Hopping (AFH) was introduced by Bluetooth Special Interest Group (SIG).In Adaptive Frequency Hopping, when a Bluetooth device is introduced in the network, it identifies the channels that are presently fixed for communication by WiFi or WLANs. It ...
Read MoreHow to remove the tick marks in JavaFX XY charts?
The javafx.scene.XYChart class is the base class of all the charts that are plotted in an x-y pane. By instantiating the subclasses of this class you can create various XY charts namely − line chart, area chart, bar chart, pie chart, bubble chart, scatter chart, etc.In the XY chart, the given data points are plotted on an XY plane. Along the x and y axes, you will have the tick marks and tick labels. The tick marks represent various values with uniform intervals.Removing the tick marksThe javafx.scene.chart.Axis class (abstract) is the base class of all the axes in XY charts. ...

Read MoreHow to create a bubble chart with two parameters in JavaFX?
The bubble chart accepts a series of data points (x, y) as input values and, creates bubbles for the data points in the given series. In JavaFX, you can create a bubble chart by instantiating the javafx.scene.chart.BubbleChart class.Generally, in all X-Y charts, the data points plot two values (x, y). In the bubble chart, there is a third value which is represented by the radius of the bubble. This chart comes handy while plotting the data points in 3 dimensions.Anyhow, it is not mandatory to have the third value, it is only optional. Like any other XY chart, you can ...

Inline chart, the data values have represented a series of points connected by a line. In JavaFX, you can create a line chart by instantiating the javafx.scene.chart.LineChart class.By default, A JavaFX Line chart contains symbols pointing out the values in the series along the x-axis. Typically, these are small circles.The X-Axis on the bottom in the plot.Y-Axis on the left.Moving the X-Axis to topThe Axis class (superclass of all axes) has a property named side, this specifies the side of the plot at which you need to have the current axis (left, right, top-bottom). You can set the value to ...
