In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in ...

Graphs are a great way to show your data and clearly identify trends. As a physicist, you will find that it is often useful to draw lines of best fit and calculate the gradient of such lines. This can ...

Feature Proposal Using a vertical gradient for the line in a diagram can add additional information. A quick look to the data can give an interpretation of the values like colours of an ample. See ...
