[英]C# wpf Live charts how to Autoadapt axis in terms of values and labels with code behind
I have a project that has to be developed in WPF and code behind only with Live charts. 我有一个项目必须在WPF中开发,代码仅在Live图表后面。 The idea is to have a temperature graph.
想法是有一个温度图。 Below you can see what I have already been doing by adding values to the lineSerie.
在下面,您可以通过向lineSerie添加值来查看我一直在做的事情。 I start by adding values to the line serie and when more than 120 I remove the first one:
我首先向行系列添加值,当超过120时,我删除第一个:
lineSerie1_Part.Values.Add(new ObservableValue((double)val));
if (lineSerie1_Part.Values.Count >= 120)
lineSerie1_Part.Values.RemoveAt(0);
Now I have two problems: 现在我有两个问题:
I would like not to have on the X axis the number of added values but the time when the temperature has been taken (eg 10:03:24 - 10:04:18 - ...). 我不想在X轴上有加值的数量,而是温度的时间(例如10:03:24 - 10:04:18 - ......)。 I have therefore written a small test program in which I set the labels:
因此,我编写了一个小测试程序,我在其中设置了标签:
Labels = new[] { "AAA", "BBB", "CCC"}; cc.AxisX[0].Labels = Labels;
and that works. 这很有效。 That said I can't change it:
那说我不能改变它:
Labels[0] = "DDD";
Labels[1] = "EEE";
Labels[2] = "FFF";
cc.AxisX[0].Labels = Labels;
does not make any change. 没有任何改变。 Additionally, is that the right way to do it?
另外,这是正确的方法吗? Would there be a way that when I add a new value, that value already has in it its x axis label?
有没有办法当我添加一个新值时,该值已经包含在其x轴标签中?
I may set the max and min temperature at the beginning (eg 18°-25°), 我可以在开始时设置最高和最低温度(例如18°-25°),
chartTemperatures.AxisY.Add(new Axis { MinValue = MinTemp, MaxValue = MaxTemp);
but I would like the graphic to automatically extend if the temperature exceeds the initial values (eg 25.5°). 但如果温度超过初始值(例如25.5°),我希望图形自动延伸。
Thanks for any help Patrick 谢谢Patrick的任何帮助
As stated by Jdweng there is not automatic method. 正如Jdweng所说,没有自动方法。 So I have to use cc.AxisX[0].Label[0] = "DDD";cc.AxisX[0].Label[1] = "EEE";cc.AxisX[0].Label[2] = "FFF"
所以我必须使用cc.AxisX [0] .Label [0] =“DDD”; cc.AxisX [0] .Label [1] =“EEE”; cc.AxisX [0] .Label [2] =“ FFF”
