如何更改堆积条形图中列的颜色?如果我在MakeBarChart函数中指定colors属性,它只接受第一个参数.并使其他列成为该颜色的较轻版本.这就是它的样子;

这就是代码;
function MakeBarChart(tmpData)
{
var barArray = [];
barArray.push(['', 'Open', 'Wachten', 'Opgelost']);
for (key in tmpData) {
if (tmpData.hasOwnProperty(key)) {
barArray.push(['Week' + key, tmpData[key]['active'], tmpData[key]['waiting'], tmpData[key]['closed']])
}
}
var data = google.visualization.arrayToDataTable(
barArray
);
var options = {
chart: {
title: 'Incidenten per week',
subtitle: '',
'width':450,
'height':300,
},
bars: 'vertical', // Required for Material Bar Charts.
'backgroundColor':{ fill:'transparent' },
isStacked: true,
colors:['#000','#1111','#55555']
};
var chart = new google.charts.Bar(document.getElementById('barchart_material'));
chart.draw(data, google.charts.Bar.convertOptions(options));

如何使列都有自己独立的颜色.
我正在制作一个存储过程,我需要使用之前设置的值.我很难解释这个,所以我将使用一个例子:
CASE
WHEN ((select top 1 stuksweergeven from componenten
where componentid = componentlink.componentid) = 1) and
((select opbrengstperkilo from componenten
where componentid = componentlink.componentid) <> 0) THEN
amount1 * (select opbrengstperkilo from componenten
where componentid = componentlink.componentid)
ELSE
amount1
END AS Total,
Amount1 * Total *(SELECT dbo.SelectReceptenLinkGewicht(Componentid,0)) AS TotalWeight

我做了一个CASE给它结果为Total.之后我想使用Total来计算TotalWeight.
对不起我的英语不好.
我在Delphi中创建一个需要特定值作为参数的函数,除非在调用函数时设置它.虽然在这种情况下会覆盖默认参数?
例:
function ExampleFunction(b = 3, a){
b*a = c
}

ExampleFunction(15,2)

是否将默认参数(3)替换为给定参数(15)?
