Charts are frequently used in business settings and can help viewers quickly grasp the information being conveyed — a valuable benefit, given the volume of information everyone must process each day, especially in today’s hyper-connected world. In Flutter we used fl_Chart in Flutter to show the relationship between multiple data sets as a graphical view.
Before we get started I urge you to go and check out our Flutter App Development Company.
A chart combines text, symbols and/or graphics to show the relationship between multiple data sets. They are a popular method for sharing information in different settings. For instance, a bar chart could show how sales of a particular flavor of ice cream have changed over the past five years. The length of each bar would indicate sales for that year.
We’re going to use the LineGraph from the fl_chart package.
Line Graphs
Line graphs typically are used to show changes or trends in continuous data over a period of time, with a line connecting the dots that represent the different values. For instance, in a line chart showing a company’s stock price over the past week, a line would connect the dots that visualize the change in price each day.
Add these two packages to your pubspec.yaml file.
fl_chart to use the chart package and date_format to format the date.
Let’s add dummy data.
Main.dart file code is here.
That’s all for this Article 🎊 .
