下面这张图片就是我现在所拥有的。
下面这张图就是我想要的。（我的代码中的第一张图片，tradingview 中的第二张图片）。
需要明确的是：我希望单行具有多种颜色。对于我的情况，我只需要两种颜色。我需要我创建的每条新线都可以改变颜色。如果右侧的价格标签也更改为触及图表右侧部分的线条的颜色，那就太好了。
这是我的代码：
var chart = LightweightCharts.createChart(document.getElementById("Chart"), {width: 1500, height: 700});
/**
* Creates startline and adds extra options to the lineSeries.
*/
function initChartSettings() {
// Init lines
priceArea = chart.addAreaSeries();
buySellLine = chart.addLineSeries(); //LINE THAT NEEDS TWO COLORS
// Set start position of lines
priceArea.setData([{time: '2019-04-11', value: startPrice}]);
buySellLine.setData([{time: '2019-04-11', value: startPrice}]);
// Visualization edits
priceArea.applyOptions({
topColor: 'rgba(70, 130, 180, 0.5)',
bottomColor: 'rgba(70, 130, 180, 0.1)',
lineColor: '#4682B4'
});
// Buy sell line
buySellLine.applyOptions({
color: '#42f54b', //CHANGES COLOR OF THE COMPLETE LINE, FROM BEGIN TO END.
priceLineVisible: true,
lastValueVisible: true
});
updateChartStatic();
}
/**
* Updates the chart its lines.
*/
function updateChartStatic() {
setTimeout(() => {
priceArea.update({
time: yearMonthDay, //How this works should not matter for question
value: newPrice, //Same as above
});
// Updates the price line of the chart.
buySellLine.update({
time: yearMonthDay,
value: currentMovingAverage //Even though it would be nice to do the below commented thing...
// color: 'red or green (example)'
});
buySellLine.applyOptions({
color: changeLineColor(currentMovingAverage, lastMovingAverage) // CHANGES COMPLETE LINE :(
});
}, 1);
}
changeLineColor() 函数正在执行 if 语句，这与为线条设置颜色无关。
