You can't have a second y-axis (yet?). In case of round-trip times isn't it possible to just store and graph them in miliseconds and display "ms or %" on the vertical label? This of course will only work when your round-trip times are not extremely high. For round-trip times upto 100 ms, the graph will plot one pixel per milisecond so your packet loss will be (barely) visible when it hits 1% If you have higher rtts or you want to see lower percentages, you could increase the height of the graph. To always start at 0, use "--lower-limit 0" as this sets the upper limit for the lower limit of the graph (it can be less, not more). To always show 0..100 and nothing else use "--lower-limit 0 --upper-limit 100 --rigid" If you leave out "--rigid", the graph can autoscale to above 100. cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
