Stock Chart

A Stock chart is extensively used to illustrate fluctuations in the data. It can represent fluctuations in stock, daily rainfall, or annual temperatures. Typically, this chart is ideal for analyzing financial data and visualizing stock information.


The data arranged in columns or rows on a worksheet can be plotted in a stock chart.


SpreadJS supports the following types of Stock charts. In the examples shown below, the market data analysis at different time intervals is depicted with the help of different types of stock charts.

High Low Close

A high-low-close chart displays the data values organized in the order: 1) high, 2) low, and 3) close with the close value lying in between the high and low values.

Open High Low Close

An open-high-low-close chart displays the data values organized in the order: 1) open, 2) high, 3) low, and then 4) close.

Volume High Low Close

A volume-high-low-close chart displays the data values organized in the order: 1) volume, 2) high, 3) low, and then 4) close.

Volume Open High Low Close

A volume-open-high-low-close chart displays the data values organized in the order: 1) volume, 2) open, 3) high, 4) low, and then 5) close.

The following code sample shows how to add different types of stock charts to a spreadsheet.

var data = dataSource;
function initSpread(spread) {
    spread.suspendPaint();

    var chartTypeStr = ['stockHLC', 'stockOHLC', 'stockVHLC', 'stockVOHLC'];
    var chartType = [{
    type: GC.Spread.Sheets.Charts.ChartType.stockHLC,
    desc: chartTypeStr[0],
    }, {
    type: GC.Spread.Sheets.Charts.ChartType.stockOHLC,
    desc: chartTypeStr[1],
    }, {
    type: GC.Spread.Sheets.Charts.ChartType.stockVHLC,
    desc: chartTypeStr[2],
    }, {

    desc: chartTypeStr[3],
    }];
