The very first time you start EaKiu it comes up showing the LINEAR Graph (subsequent starts will show the graph you last were viewing). The LINEAR Graph combines all the different tracked data values on one graph, thus the name Multi-Graph. Furthermore, with version 3.0 of EaKiu you can now customize the LINEAR Graph to show you only the components you are interested in. If EaKiu is not in LINEAR Graph mode, you can place it in that mode by clicking the 2D button in the GRAPH button area, or by typing the g or G key until the 2D button lights. When EaKiu is in LINEAR Graph mode, the GRAPH button area will show the 2D button lit green like this:
 The Graph area will show the LINEAR 2D Graph and will look like this:
 In the LINEAR Graph the horizontal axis is divided into the 85 different frequencies between 2400 MHz and 2484 MHz (this is the B and G wireless spread). The horizontal chart lines represent the actual channels within that range. Below the chart the channel numbers will appear in white below their specific frequencies. The vertical graph is divided into dBm (signal strength). The closer the signal is to 0, the more powerful it is. A signal at or below -60 dBm is basically nonexistent. At the bottom of the chart will be a series of bouncing yellow bars. These represent the Average signal at each frequency position. (See below to find out how to switch between AVERAGE and CURRENT for these bars). The RED LINE shows the current Peak value and decays in time. Once a yellow bar goes high the red line will hold that position for 2 seconds before moving back towards the yellow bar. This represents the Short-Term Peak of each frequency. The gradient bluish to red/white lines show the Maximum signal strength and also decays in time. After this line has peaked for a minute (60 seconds) it will begin to decay to the current short-term peak. This lets you see the Long Term Peak (or maximum) of the signals amplitude. The colors of this line correspond to the dBm colors and the signals strength. The little white dots stay at the True Maximum and never fall down. This shows the Overall Maximum that each frequency has reached. You can zero both the (Long Term Peak) and (True Maximum) lines by clicking the Zero Max button in the CONTROL area, or by typing the z key. You can zero ALL the data by clicking the Zero All button in the CONTROL area, or by typing the Z key. While viewing the LINEAR Graph you can move your mouse cursor into the chart area to view the Frequency and Signal Strength of that point in the chart. The vertical portion of the chart will 'auto-range' to the maximum of the incoming signal amplitude. When the chart starts off, the right side will show dBm -60 to -55. As signals begin to be sampled the top of the chart will dynamically change to represent the maximum amplitude sensed up to that moment in time. If you wish to change the vertical range of the chart, use the (single quote) and " (double quote) keys. The single quote key will lower the range of the chart (towards -60 dBm) while the double quote key will raise the range of the chart (towards 0 dBm). Once you use either key to modify the chart auto-ranging will no longer occur (unless you clear the chart data, or reset the controls, or restart the program). USING THE VIEWING-MODE BUTTONS On the left side of the Graph area are four buttons known as the VIEWING MODE BUTTONS, and marked A, C, P, and M. These four buttons work differently for the 2D LINEAR mode than the other 3 modes (3D SPECTRUM, QUAD, and WIRE). When EaKiu first starts running, the A, P, and M buttons are lit and the C button is dim. These four buttons allow you to custom tailor what data is being shown in the 2D LINEAR MULTI-GRAPH. The top two buttons, A and C, toggle between each other. That is, if A is lit and you click on C, the A button will dim and the C button will light. The bottom two buttons toggle independently and each can be turned on and off individually. The 'A' Button The A button shows the AVERAGE signal. The amount of the averaging is set in the SETTINGS area in the AVERAGE value. You can change this value by click the left button over the value and mousing left and right, or by typing the { and } keys. The AVERAGE signal is shown by the bouncing yellow bars. The 'C' Button The C button shows the true current signal without any averaging. The CURRENT signal is shown by the bouncing yellow bars. You can toggle back and forth from A to C. The 'P' Button The red line shows the short-term peak as a decaying signal over 2 seconds of time. Turning the P button off will turn off this peak line. Turning the P button on will show the peak line. The 'M' Button The gradient vertical lines shows the long-term maximum as a decaying signal over 1 minute of time. Turning the M button off will turn off the maximum lines. Turning the M button on will turn on the maximum line. Combining The Buttons You can combine the four buttons in most any combination with the exception being that only A or C can be lit at any one time. You can also turn all four buttons off. To turn the A or C button off, simply click the button that is on. When all four buttons are dim (off) the graph shows the white maximum dots as a gradient colored line (instead of the dots). This is a special mode for tracking just the maximum in a more friendly way than by using just the dots.
