帶有LegendBox的儀表板

儀表板允許使用最少的內(nèi)存資源高效地在單個(gè)視口中渲染多個(gè)場(chǎng)景。在創(chuàng)建儀表板實(shí)例的過(guò)程中，必須指定行和列的數(shù)量。此后無(wú)法更改。

// Create a dashboard with three rows and two columns.
const dashboard = lightningChart().Dashboard({
    numberOfRows: 3,
    numberOfColumns: 2
})

// Create a ChartXY that occupies the top row of the dashboard.
const chartXY = dashboard.createChartXY({
    // Row index (starting from bottom).
    columnIndex: 2,
    // Column index (starting from left).
    rowIndex: 0,
    // Row span (height, basically).
    columnSpan: 1,
    // Column span (width, basically).
    rowSpan: 2
})

儀表板具有用于添加不同種類的圖表或面板的單獨(dú)方法。儀表板代表具有行和列的網(wǎng)格。在創(chuàng)建元素期間，應(yīng)指定行和列索引以及水平和垂直跨度，以將其放置在正確的位置并填充所需數(shù)量的單元格。

// Create a spider chart and attach to dashboard.
// Row 0, Column 0, Rows to fill 2, Columns to fill 1.
const spiderChart = dashboard.createSpider( 0, 0, 2, 1 )

// Create a Legend Box Panel and attach to dashboard.
// Row 0, Column 1, Rows to fill 2, Columns to fill 1.
const legendBox = dashboard.createLegendBoxPanel( {
    columnIndex: 0,
    rowIndex: 1,
    columnSpan: 2,
    rowSpan: 1
})

// Set height of the first row of a dashboard.
// By default each row and column has a size of 1.
// The size is always relative to the combined size of each row / column.
dashboard.setRowHeight( 0, 2 )
// Set width of the first and the second column of a dashboard.
// First column width will be 2/5 of the entire view's width.
dashboard.setColumnWidth( 0, 2 )
// Second column width will be 3/5 of the entire view's width.
dashboard.setColumnWidth( 1, 3 )
