Import the matplotlib.pyplot library into your project. I have this so far: How do I make it so instead of going on an angle between the points the line stays flat? I found this post but it deals more with an animation and not just plotting the function. Parameter 2 is an array containing the points on the y-axis. To be clear, I don't need or want a square graph, but I need the units to look square at all times no matter the graph aspect ratio or length of either axis. Use the xlabel () function to add x-axis labels. Is there a way to make unfilled markers in the scatterplot? facecolors = 'none' Draw a square-aspect log-linear plot via matplotlib. To fix this problem, you can set the aspect to the ratio of xaxis range and yaxis range: To location the colorbar we need write a ColorBarLocator Class, the pad and width argument are in pixel unit. But to finish off the answer about lining the squared plots up nicely, you could trick matplotlib into thinking that both plots have colorbars, only making the first one invisible: To add to the other answers, you need to take the absolute value of arguments to Scatter plots are used to plot data points on horizontal and vertical axis in the attempt to show how much one variable is affected by another.
