Hi Hit-Mickey, Your program doesn't have reached to last number that is 100. So, you see the intermediate plot. Best regards, Take

Thanks for replying. But When I use python matplot, I find there is no straight line in the middle.The figure and code are attached with this email. I wonder if there is a little problem in the matplotlib-cpp. Sorry to pradon you,and I will be very grateful if you can solve this problem.

Hi, I understand that you mean just now. You can solve this problem with no size vector and push_back(..) function. Best reagard,

#include "matplotlibcpp.h"
namespace plt = matplotlibcpp;
#define N 100
int main(){
	std::vector<double> x,y;
	plt::figure();
	for(int i=0;i<N;i++){
		x.push_back(i);
		y.push_back(log(i));
		plt::clf();
		plt::plot(x,y);
		plt::pause(0.01);
	}
	plt::title("test");
	plt::show();
}
