Graph
These options decide how DU Meter draws the traffic, what the top of its graph stands for, and its colors.
Graph style
Type: curves, or bars of ten seconds each. The bars are solid blocks, which some of our users with less than perfect eyesight find easier to read.
Download and upload: In one graph, the download and upload curves lie over each other, and a bar stacks the upload under the download, so that its height is the two added. In two graphs, download grows upwards from a line across the middle and upload downwards: choose this, with a speed of its own for upload, when the two differ greatly.
Show Wi-Fi signal quality: in one graph, a violet line shows the quality of the Wi-Fi signal, 0% at the bottom and 100% at the top. 100% is virtually never reached; anything above 75% is excellent. A sudden change in speed can then be told apart from a change in the signal. Without a wireless connection there is no line, and on a computer without a Wi-Fi adapter the option is not shown.
Vertical grid lines: every 10, 20 or 30 seconds, every minute, or none.
Graph scale
Show the scale label writes at the top of the graph what that top stands for.
Download and Upload set what the top stands for. With Automatic, it is the most the graph shows, so that low and high traffic alike fill it. With the speed of your connection chosen, or typed in after choosing Custom speed, the top is that speed: one glance shows how much of the connection is in use, and a quiet connection lies flat.
Uploads are often much slower than downloads. Chosen apart from download, even as Automatic, upload has a scale of its own in two graphs, and its changes stay visible next to a much faster download. With Same as download, both use the download's. Bars in one graph stand for the two added, and so does their top: the two speeds together.
Tip
You can use the Stopwatch to accurately measure average and maximum transfer rates over a specified period of time.
Graph colors
Use custom graph colors lets you choose the colors of received and of sent data, for the graph and the arrows, in the dark and in the light color mode alike. All other colors follow the color mode. Reset to defaults sets the two colors back to DU Meter's.
