Why we created these #chartjs and #javascript video tutorials?

WHY
Creating charts in javascript is very rewarding but extremely challenging. The Chart JS library made it easier to render charts. However the chart js documentation is hard to understand for many. It requires a lot of different moving parts to work along. The canvas tag, javascript, arrays and Chart JS all need to be combined to draw an eye catching bar chart or line chart.

The videos explains the chart js documentation in a more visual and easy to understand way. You can follow along with the code and quickly grasp how it works. We cover the code in chart js but also what truly happens and why something happens when we write a line of code. This fundamental understanding gives clarity to you as a developer in chartjs. In short it is the Chart JS video documentation.

HOW
We answer questions from YOU (viewers) by creating an answer video that covers the questions YOU have posted in the comment section.

WHAT
Our goal is to help YOU learn how to draw charts in Chart JS by showing you in video format how to do it.

Thanks a lot for the video, it helped me a lot. I'm using it to create a graph form a CSV file with 3 columns. One id for the X axis and another one is for the Y axis. The 3rd one is to mark if a value is correct or not, like a tag, and I would like to know if it is possible to create the graph using only the rows that match certain values from that 3rd column. For example create the graph using only those rows that have a 0 in that 3rd column, like a filter. Thanks a lot!

Thank you for the video! I have a couple of questions. 1) can we create a custom x-axis? For example population of cities(yaxis) and citi names(x axis) and cities from same country must be grouped and show the country name below cities names.

2) Draw x-grid lines after each country I.e if the data has information about 3 cities in canada, grid line must be drawn after 3 data points
