Hi Sir, nice learning video, I have a quick question, I would like to prepare a graph with x axis as timeline (lets say every hour ) and y axis - Some Job Name (A, B, etc), The start time and end time for each job should be represented in bars . (Assume like job monitoring). Lets say Job A started today 1'o clock and ended at 3'clock - The rectangular bar for Job A should be in parallel to x axis from 1 to 3 . Can you help on this?Thanks in Advance!

Great video. You went straight to the point. Respect.

With due respect, I believe we should plot overlapping histograms rather than putting them side by side in one plot. This way we are compromising with the bin width for men and women data. For bin size 80-100, men data bin width is 80-90, and for women data, bin width is 90-100.

Great videos really simple to understand. Would you make a video on Machine learning, Neural network, Support vector machine? Thank you so much.

Thank you so much. Excellent tutorial.

Thanks for video, this is so useful. And beautiful accent...

This is confusing because though both sets share a range (say 80-100) the illustrations suggests that one set has values between 80 and 90 and the other set has values between 90 and 100. What would be useful is if the x axis is relabelled according to range e.g. 80-100 and both bars for each data set share that range. Can you remedy? ...

nice, but how to incorporate standard deviation or standard error bars? kindly explain that also

Hi, can you also show how to create mekko bar chart in python

Hi, Please provide some insight on the below-

Case 1 ---
When I do the below
n, bins, patches = ax[0].hist(data, 20, alpha=0.5)
I get count on y axis for values that are in corresponding bins on x axis.

Case 2 ---
Then I do the below
n, bins, patches = ax[1].hist(data, 20, density='true', alpha=0.5)

Case 3 ---
and then plot the best fit line-
mu, sigma = scipy.stats.norm.fit(data)
best_fit_line = scipy.stats.norm.pdf(bins, mu, sigma)
plt.plot(bins, best_fit_line)

In case 2 and 3, I get probability distribution on y axis.

I want to achieve case 2 and 3 together but I want Counts on y axis as the way they are shown in Case 1. How to do this?

sir if I want to show the number of percentage how to do that
thanks for your videos

sir where to use these matplotlib, how to know for the data to use which chart

[utpalkantkumar]

can We have green and yellow in Same bar ? mean we can do Men is dark green and women is light yellow ?
