When the stage renders we check the value of isAsync and change the title of the chart. Then we create an event listener which is fired when the stage is rendered. To understand better what kind of ramification of asynchronous rendering could be, please take a look at the sample code below.įirst, we create isAsync variable and assign false to it. providing no parameter means default: synchronous This may be okay if your page is small and contains only a chart or two but in the case of large dashboard, such behavior may become undesirable.Īn圜hart lets you decide if you want to go with synchronous or asynchronous rendering, you can set this by providing a boolean parameter to draw() method: var chart_1 = anychart.pie() When I generate the chart with the data, it is plotted correctly on the screen but when I export it to svg, it is exported but without the descriptive texts located on the edges of the chart. When this process is executed synchronous web page doesn't react to anything and waits until chart appears. I am using version 8.11.0 of Anychart in an Angular 13 project. plotly.js is free and open source and you can view the source, report issues or contribute on GitHub. plotly.js ships with over 40 chart types, including 3D charts, statistical graphs, and SVG maps. When we speak of charting in JavaScript the most lengthy process is rendering: we have to create SVG or VML image, add it to DOM and so on. Plotly JavaScript Open Source Graphing Library Built on top of d3.js and stack.gl, Plotly.js is a high-level, declarative charting library. With synchronous execution, your program is "stuck" waiting for the process to end, with no way out while asynchronous execution avoids this bottleneck. Synchronous execution can have undesirable consequences when a function called starts a time-consuming process. Each time a function is called, code execution waits until that function does everything it needs and makes a return before continuing to the next line. Synchronous program execution is somewhat similar to this: your program is executed line by line, one line of code at a time. When you execute something asynchronously, you can move on to another task before it finishes. When you execute something synchronously, you wait for it to finish before moving on to another task. Rendering charts asynchronously may boost your web application (page) responsiveness and improve better user experience but you always need to understand what asynchronous execution implies and code your application accordingly. Triple Exponential Moving Average (TRIX)Īn圜hart charts can be rendered both synchronously and asynchronously.Moving Average Convergence Divergence (MACD).
