So I have been trying to generate a heatmap in python such that the Matplotlib graph that is generated does not have any white margins in both x and y axes and the graph's scaling must be 1:1 with respect to the x and y axes units. I have tried many things but the best I have been able to achieve so far is able to remove the x axis white margins but not the y one. Here's an example: This is what I am getting: This is what I want:
Here's the code through which I am generating the graph:
plt.style.use('classic') plt.axis('equal') plt.pcolormesh(x_mesh,y_mesh,intensity) plt.plot(x,y,linestyle="None",marker='.',markerfacecolor='white') #plt.colorbar() #plt.axis('off') plt.margins(x=0,y=0) plt.ylim([0,254]) plt.xlim([0,538]) plt.savefig('plottest.png', dpi=144, bbox_inches='tight', pad_inches=0) plt.show()
Any help would be highly appreciated! Thanks!
