How are live charts and graphs used in JavaScript?

JavaScript Live / Dynamic Charts & Graphs Dynamic or Live charts are useful in displaying data that changes with time like stock price, temperature, real time sensor readings, etc. Dynamic Chart are also known as Real Time charts.

How to use x axis in chart.js?

The x-axis data points may additionally be specified via the t or x attribute when using the time scale. When providing data for the time scale, Chart.js supports all of the formats that Moment.js accepts. See Moment.js docs for details. The following options are provided by the time scale.

What can you do with cubism.js plugin?

Cubism.js is a D3 plugin for visualizing time series. Use Cubism to construct better realtime dashboards, pulling data from Graphite, Cube and other sources. Cubism is available under the Apache License on GitHub.

How often does Cubism update charts on GitHub?

Cubism renders incrementally, too, using Canvas to shift charts one pixel to the left. This approach lets Cubism scale easily to hundreds of metrics updating every ten seconds! Despite asynchronous fetching, rendering is synchronized so that charts update simultaneously, further improving performance and readability.

How are position and color used in Cubism?

By combining position and color, horizon charts improve perception: position is highly effective at discriminating small changes, while color differentiates large changes. To further increase data density, Cubism favors per-pixel metrics where each pixel encodes a distinct point in time.

Which is better Cubism horizon chart or standard area chart?

Cubism’s horizon charts make better use of vertical space than standard area charts, allowing you to see many more metrics at-a-glance and increasing the likelihood of discovery. If you compress a 120-pixel tall area chart to 30 pixels, you lose 75% of the resolution and it becomes harder to see small changes:
