Note: We may call the ID whatever we wish, however it is advised that we pick a descriptive name that represents the type of charts we want to generate. More information regarding the Canvas API may be found here.Īll we have to do is construct the canvas tag within the body tag and provide an ID that we will need to call fetch the element and reference our specified graph element in JavaScript: We conducted a meta-analysis to determine the correlation between DLC-1 expression and clinicopathological characteristics in cancers. 4.8.4.4.3 A phrase or paragraph with an alternative graphical representation: charts, diagrams, graphs, maps, illustrations.

Levels are plotted on one chart axis, and values are plotted on the other axis. Here is the information we will be using: JavaScript Framework What is a bar chart A bar chart (aka bar graph, column chart) plots numeric values for levels of a categorical feature as bars. Creating Charts With Chart.JSįor this guide, we will create several sorts of charts, highlighting the most popular JavaScript frameworks based on the amount of GitHub Stars they currently have.
