java - Need two extract co-ordinates value of x & y axis from a image chart? -

-

i have images of different chart (ex. pie chart , bar chart etc.).can body tell me how co-ordinate value of each point draw @ chart ???

thanks in advance

since images (aka, not charts created within java), real option analyze charts images, using along lines of imagej (i use pil in python, similar that) convert image matrix of rgb values, can use distinguish colors of each slice of graph, , use matrix coordinates starting point generating (x,y) coordinates.

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.
