Bar Chart in Google Charts
Bar Chart
A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart. Bar charts are rendered in the browser. Bar charts display tooltips when the user hovers over the data.
Steps for adding Google Bar Charts to your Website:-
- To use Google Bar Chart on your website, add a link to the charts loader.
- After this, add a div with a unique id. Then, we have to load Google Graph API.

- Set a callback function.
- The visualization API is:- google.charts.load('current', {'packages':['corechart']})
- The callback function will be:- google.charts.setOnLoadCallback(draw_my_chart)
