How can I create a heatmap using Matplotlib?
You can create a heatmap in Matplotlib using the imshow
function. Do you have specific data you want to visualize?
Yes, I have a 2D array of values representing temperatures.
Great! You can use plt.imshow(data, cmap='hot', interpolation='nearest')
to display your temperature data as a heatmap.
What does the cmap
parameter do?
The cmap
parameter specifies the color map used for the heatmap. 'hot' will give you a gradient from black to red to yellow.
