java - Displaying all XYSeries at once in jFreeChart for improving speed -


suppose need display multiple xyseries in single xyseriescollection. problem every time add xyseries, jfreechart wants update chart , slows down process of displaying multiple xyseries.

what want similar this:

// not update chart xyseriescollection.add(xyseries1) xyseriescollection.add(xyseries2)  ... xyseriescollection.add(xyseries10) // update chart

how can this?

construct new xyseriescollection having desired series, , invoke setdataset() on xyplot. generate single datasetchangeevent.

addendum: here's sscce updates n series, each having n2 values. performance question, example may helpful in profiling.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
