c# - WPF Toolkit hide "Key" value in Area Chart -

-

i have chart displays cpu usage. uses following code add values , refresh:

cpuchartvaluelist.add(new keyvaluepair<string, int>(i.tostring(), icputotal_usage)); cpu_chart.datacontext = cpuchartvaluelist; cpu_chart.refresh();

in string value there recorded seconds , int value contais cpu usage.

chart rendered correctly can't rid of key string value showing in chart. im sitting 2 hours on , still can't find solution.

cpu usage

everything works can't hide "seconds". if add new x-axis , set hidden wpftoolkit adds new axis these seconds on top (what going on?)

second chart

i've run out of ideas. grateful if provide me way disable this.

waiting best regards

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
