It allows users to plot data and render the customized chart types with seamless interactions and responsively smooth animations. Flutter has the following advantages over other cross-platform mobile app development frameworks:. Syncfusion Flutter charts are rich in features, including functionality for rendering Cartesian charts, circular charts, pyramid and funnel charts. They are completely customizable and extendable, and their feature lists will expand aggressively in upcoming updates.
Have a look at the following current features. Each chart type is easily configured with built-in support for creating stunning visual effects. You can add any number of series to the chart.
Features such as markers, data labels, data label builder, animation, gradient fill, dashes, sorting, and annotations are easy to incorporate and customize.
Axis features such as label intersecting, edge label placement, label rotation, axis opposition, inverse axis, and multiple axis allow users to customize axis elements further to make an axis more readable. Display additional information about a chart series using legends.
The chart legends can also be used to collapse the series. Legends can be wrapped or scrolled if items exceed the available bounds. A chart can be updated dynamically with live data that changes in seconds, like stock prices, temperature, and speed i. Also, the entire data source of the chart can be replaced completely. Add a chart widget as a child of any widget. Here, we are adding the chart widget as a child of the container widget.
Based on your data, initialize the appropriate axis type and series type. In the series, you need to map the data source and the fields for x and y data points.
Since we are going to render a line chart with a category axis, I have initialized them. Finally, add Syncfusion Flutter Charts elements such as title, legend data labels, and tooltips to display additional information about the data plotted in chart.
Next, we are planning to implement Calendar and other data visualization widgets in Flutter and add chart types and usability features in the Charts widget. If you would like us to add a new widget, or if you have questions about our Flutter charts, please let us know in the comments section of this post. In this blog post, we walked through our new Syncfusion Flutter Charts widget and discussed our future plans. We invite you to try out the widget and provide your feedback to make it more robust before its final release.
This helps us prioritize the next set of controls and features to implement. You can simulate the appearance of Apple watch rings with the existing chart features. Please find the output from the below link. Here we have rendered the radial bar chart with 3 values move, stand and exercise. Also, legend and tooltip have enabled in this example.
We have attached the example project below for your reference. The main features I need are: range overlay on graph based on axis position, multiple series on single graph and possibly annotation points below axis. Does your package provide this features? Does you package provide a method to save the chart as a image? We have analyzed your queries. I hereby confirm that the Syncfusion Flutter widgets are highly maintainable.
We will revert back to you within 24 hours. You can render multiple series types in a chart and you can find the sample for this from the below location.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Simply each circle represents the total value of percent and each division contributes some percent to the total. Start Your Free Excel Course. There are different types of PIE charts available in excel. We can view that by clicking on a Pie chart drop down option. Go to charts segment and select the drop down of Pie chart. Which will show different types of PIE charts available in excel. We will see all those charts one by one with an explanation.
We can use the same data for all those charts. We will take a very small data table which is related to employee salary usage. Observe the below table which expresses the expenses of the employee. Now go to PIE chart options which are already explained earlier. Select the type of PIE chart we want to create. First, we will select the first PIE chart from 2D charts. The chart will look like below. A PIE chart is created with different divisions and each division is represented with different colors.
At the bottom, there is a legend which will help to understand what color represents what division on the chart. But it will be difficult to check the description in the legend and check it on the chart. Now our task is to add the Data series to the PIE chart divisions. Now each division on the chart represents its name and contributed percentage. In case if we want to add the amount alone to the division. In case if we want to add the expenses category to the division.
If we want both select both options. To create this, we just need to choose the Pie of pie option instead of Pie chart as earlier. In this pie of pie chart, we will have two pie charts. First one is normal Pie chart and the second one is subset of main pie chart. If we add the labels, then will understand what is covered in the sub chart.
The sub chart has only two categories which are representing the break up of If we add the labels, then it will show what categories cover the sub Pie chart. Sub pie chart has school fees and savings which are representing as other in the main part chart. Now, while creating the chart just select the Bar of Pie chart then the below chart will be created.
It is as similar to Pie of the pie chart but the only difference is instead of a sub pie chart a sub bar chart will be created. With this, we have completed all the 2D charts and now we will create a 3D Pie chart.Pie charts are one of them most commonly used charts for data visualization, primarily because they are as easy to create as they are to understand.
Technically defining, a pie chart is a statistical graph for plotting numerical proportions. The independent variable is plotted in clockwise or anticlockwise direction on the circular graph. The magnitude of the dependent variable is proportional to the length of the arc on the circumference of the graph. Radial lines are used to connect the arcs to the center of the circle, thus dividing the pie into slices.
The independent variable can assume a finite number of distinct values; the dependent variable, usually a percentage, can take any value between 0 and percent. Before we move on to talk more about the pie chart and the kind of data that can be plotted and analyzed using the pie chart, we'll see a simple example for this chart. Take a look at the pie chart shown below, used to showcase product-wise sales for the last quarter in Harry's FashionMart:.
This pie chart gives you a quick comparison between the sales of each category and the total sales of the last quarter. One look at this pie chart and it is easy to deduce the following points:. This said, like all charts, it is important to determine if a pie chart is suitable to visualize your data.
Forcing a chart to fit to your data can only result in poor data visualization and, consequently, incorrect data analysis.
Getting Started with Syncfusion Flutter Charts
The section below tells you the what and why about the type of data a pie chart should be used to showcase. You need to do a part-to-whole data analysis. For a part-to-whole analysis, pie charts have been found to be better than the column and bar charts.
They are also easy to understand by even users who don't have a statistics background and therefore are preferred for showcasing data meant for public consumption. When comparisons between approximations are enough for a discussion and you don't need to get into the specifics, pie charts are your best bet. You have a small number of categories to compare. One reason why we could easily make deductions from the sample pie chart shown above is the number of categories plotted on the chart.
With just four categories plotted on the chart, it is easy to assess the proportion of each category. This makes data analysis a cake walk or should we say a pie walk! The general rule of thumb says that pie charts should be used when the number of categories is three or less than three. While sticking to having just three categories on a pie chart maybe a difficult proposition in some use cases, pie charts are best used when rendered uncluttered.First of all, Graphs and Charts are essentially utilized for speaking to and arranging a lot of numerical information with a graphical portrayal, for example, pie diagram, line charts, reference charts and some more.
The static images would be decreased utilizing these methods and empower more access to the substance of the charts and the graphs. The significant component of the Bootstrap diagram or graph is that it enables the clients to effortlessly download by decreasing the transmission capacity necessities of the HTML page.
Some of the Bootstrap 4 graph charts we will discuss are the Pie chart, line chart. There are various strategies that would make a style in the graphs and charts.
In any web industry, a great and incredible introduction of the information assumes a significant job in making the clients comprehend the substance of your examination.
The polished skill ought to reflect in the information introduction and the watchers ought to have the option to get a handle on the substance snappier. With the Bootstrap charts or graphs, it is very conceivable to show a piece of OK information which could be very clear and straightforward. The information ought to be advantageous to analyze successfully and the clients must close the correct choice with the information introduction.
Remember that it is very fundamental to build up a unique web chart with the goal that the numerical information factors are very simple to change or could be refreshed whenever. The Bootstrap-based charts or graphs are very easy to make and produce static harts and we could likewise style them as indicated by our prerequisites.
As should be obvious the designer has given you both the Pie chart and the column chart in one single page. The pie chart is partitioned into numerous cuts to delineate a particular extent. Likewise here the designer has separated every one of the information in a satisfying way. The cuts of the pie chart shimmer on the float. On the snap, the cut moves a little up from its position.
Alongside that, a line is demonstrated simply out of each cut of the pie chart to give extra data. A column chart is a graphic portrayal of information. The designer has shown vertical bars going over the chart on a level plane, with the qualities hub being shown on the left half of the chart. ChartJS gives wonderful level structures to charts.
Google chart apparatuses are ground-breaking, easy to utilize, and free. Here the designer has structured a similar modular like the google chart.
