Sometimes, you might get a few samples *way* out of range, though, that stretches the scale. Normally, setting the graph scale to automatic works pretty well. You can change to a fixed scale in the options screen. If a fixed scale is being used, this number will always equal that scale. This number can change (and WILL change) as new samples are received. If a dynamic scale is being used, then this number is the maximum response time of any of the included sample set. The number shown here indicates the graph scale, in milliseconds (1/1000th of a second). As you increase your window, though, a single bad sample can make this line stretch the scale of the graph. When showing just a few samples, this can be really handy to see the range of latencies. It may be distance (ie: speed of light latency), or it may be a problem with one router, or the connection between those routers. This line can be useful to understand how a specific hop is responding - for example, if hop 8's minimum point is significantly greater than hop 7's maximum point, then you may need to investigate what's happening between hops 7 and 8. Hide this line to keep the scale of the upper graph in better range. You might want to turn this off when submitting a picture to an ISP so as not to confuse them or add anything they can question. A little blue X will be drawn on the graph that represents the most recent sample. To watch 'trending', it's sometimes nice to see what the most recent sample is. For a modem, 200 ms might be quite good, while for a T1, it could be considered bad. This is dependent on your expected performance. If you have a modem, you probably want to crank these numbers up a bit.Ĭhanging these values sets the Green / Yellow / Red threshold for the graphs. If you've got a T1 or a cable modem, the listed numbers are probably pretty good (you might move them down a little if you're tracing to a fast site). You'll probably want to change the numbers based on your internet connection speed. In addition, the legend on the graph screen will be updated with these number.

These numbers apply to both the HOP column and the graph background. From 201 to 500 will paint yellow, and over 500 will paint red. By default, all response 200 ms and below will paint green. These boxes control the point at which the colors change.

Turn off this switch to use a non-color background.

Some 256 color graphics drivers might not look very good with the colors on the graph. Turn off this option if you're having problems seeing the graph (ie: It has little speckled dots instead of a solid color). The background of the graph uses colors that don't display well unless your video drivers are set for more than 256 color. If you want to minimize on-screen color, turning this off will hide the green, yellow and red background color on the hop (first) column. The 'Display' settings control the general display format of PingPlotter’s graphs, including scaling, coloring, and other general values.
