我正在嘗試創(chuàng)建一個(gè)測(cè)量系統(tǒng)，可以使用 LiveCharts 測(cè)量 Y 軸上的值和 X 軸上的時(shí)間。我使用Constant Changes作為基礎(chǔ)來(lái)創(chuàng)建我的圖表，但我希望我的 X 軸從 0 秒開始，而不是像示例中那樣從當(dāng)前時(shí)間開始。我已經(jīng)嘗試過(guò)如何使用 Livecharts 使 x 軸從 0 開始并有 2 秒的步長(zhǎng)，而不是盯著程序啟動(dòng)的第二秒？但我無(wú)法讓它與我的程序一起工作。我想做他們?cè)谏厦骀溄拥木€程中做的同樣的事情，但無(wú)法讓它工作。我的輸出/它看起來(lái)如何代碼隱藏： public void init() { var mapper = Mappers.Xy<ValueRandomizerForTest>().X(model => model.DateTime.Ticks).Y(model => model.Valuefordate); Charting.For<ValueRandomizerForTest>(mapper); ChartValues = new ChartValues<ValueRandomizerForTest>(); DateTimeFormatter = value => new DateTime((long)value).ToString("ss"); AxisStep = TimeSpan.FromSeconds(1).Ticks; AxisUnit = TimeSpan.TicksPerSecond; SetAxisLimits(DateTime.Now); }public void read() { var r = new Random(); while (isreading) { Thread.Sleep(550); var now = DateTime.Now; var test = now.Second; _trend = r.Next(1, 100); if(ChartValues.Count == 0) { } ChartValues.Add(new ValueRandomizerForTest { DateTime = now, Valuefordate = _trend }); SetAxisLimits(now); //lets only use the last 150 values if (ChartValues.Count > 150) { ChartValues.RemoveAt(0); } } } public void SetAxisLimits(DateTime now) { AxisMax = now.Ticks + TimeSpan.FromSeconds(1).Ticks; //Axis is moving 1 second ahead AxisMin = now.Ticks - TimeSpan.FromSeconds(5).Ticks; }

見內(nèi)聯(lián)評(píng)論：
private long startTimeTicks;
public void init()
{
var mapper = Mappers.Xy<ValueRandomizerForTest>().X(model =>
model.DateTime.Ticks).Y(model => model.Valuefordate);
Charting.For<ValueRandomizerForTest>(mapper);
ChartValues = new ChartValues<ValueRandomizerForTest>();
DateTimeFormatter = value => new
DateTime((long)value).ToString("ss");
AxisStep = TimeSpan.FromSeconds(1).Ticks;
AxisUnit = TimeSpan.TicksPerSecond;
var currentTime = DateTime.Now;
startTimeTicks = currentTime.Ticks; // store start time
SetAxisLimits(currentTime);
}
public void read()
{
var r = new Random();
while (isreading)
{
Thread.Sleep(550);
var now = DateTime.Now;
var test = now.Second;
_trend = r.Next(1, 100);
if(ChartValues.Count == 0)
{
}
ChartValues.Add(new ValueRandomizerForTest
{
DateTime = now - new TimeSpan(startTimeTicks),
Valuefordate = _trend
});
SetAxisLimits(now);
//lets only use the last 150 values
if (ChartValues.Count > 150)
{
ChartValues.RemoveAt(0);
}
}
}
public void SetAxisLimits(DateTime now)
{
long offsetTicks = now.Ticks - startTimeTicks; // compute offset ticks from program start (at call from init() this calculation will be equal to 0)
AxisMin = Math.Max(offsetTicks - TimeSpan.FromSeconds(5).Ticks, 0);
AxisMax = AxisMin + TimeSpan.FromSeconds(6).Ticks; // Set max according to min
}
