javascript - x-axis <g> tag transform not transitioning -


i have 2 x-axes on horizontal bar chart, , when created both given transform translates them vertically (.attr('transform', 'translate(0,' + (height - 5) + ')');). when data point removed, chart shrinks, changes height variable, changes transform. if try add transition, nothing happens. doesn't not animate, doesn't set transform. without animation @ least sets transform (just way early, looks weird else shrinking).

here's relevant code: 

chart.select('.x-axis.top').transition().duration(1500)   .attr('transform', 'translate(0,' + (height - 5) + ')');

again, if remove .transition().duration(1500), transform @ least still changes.

update

while modifying lars kotthoff's jsfiddle match code i've been working on, figured out problem was. this:

svg.select('.x-axis')     .transition().duration(1500).attr("transform", "translate(0,100)"); svg.select('.x-axis')     .transition().duration(1500).call(axis);

in order animate ticks of axes, running .call(axis) after data updated. code snippet obvious should try tack .call(axis) onto end of first call, , of course after worked.

this example bit contrived; in code i've been working on there's logic (that's turning off transitions when chart first initialized) seperates 2 functions.

i considered answering own question, while fix pretty quick , obvious, still think it's weird second call should prevent first 1 working correctly. question still stands, suppose, why doesn't seem work, instead of how fix it. here's updated jsfiddle shows problem.

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
