JavaScript Large Line Chart

This example showcases visualization of a Line chart with relatively large data set (several millions of data points).

LightningChart JS has created a revolution with the possibilities of data visualization in web - previously Line chart visualization was realistically possible only to ranges of some hundred thousand data points and even then it required complicated developer effort to enable any zooming or panning interactions with satisfactory performance.

With LC JS a million points Line chart is loaded in less than a second and the result is unlike anything seen before - operations like zooming and panning are instantaneous.

Additionally, when compared to previous alternatives, the usage is ridiculously simple. With SVG/Canvas based drawing, users would have severe limitations with large data amounts as these technologies don't scale well.

Here's how simple the creation of a million points line chart is with LC JS:

const chart = lightningChart().ChartXY()
const series = chart
        dataPattern: {
            pattern: 'ProgressiveX',
    .setStrokeStyle((stroke) => stroke.setThickness(1))
    .addArrayY(new Array(1000000).fill().map((_) => Math.random()))

This takes about 100 milliseconds to load and will immediately be interactable with lightning fast reactions!

The maximum possible Line chart size scales well with used hardware, especially RAM (memory) and GPU (graphics card) - On average office PC, LC JS can handle more than hundred million data points.
