Start

We can use this library in the following ways. first of all,make sure you are in a wpf project

you can download and add this like a User Control Library.and also you can get it from nuget.

more information: https://www.nuget.org/packages/PlotLab/1.0.2

For Example

xmlns:controler="clr-namespace:PlotLab;assembly=PlotLab"

and then you can add component like follow

<controler:PlotChart x:Name="plot"/>

and you must add reference in your code file

using System.Drawing;
using PlotLab;

you can add data points as below:

  plot.Sequence = new Sequence(new List<SequenceEntity>() {
            new SequenceEntity(new List<float>() { 1,2,3,4,5,6,7}),
            new SequenceEntity(new List<float>() { 0,5,3,4,5,6,7},Pens.Brown,"example 1"),
            new SequenceEntity(new List<float>() { 0,3,3,4,5,2,1},Pens.Green,"example 2"),
        });

using 'add' is also allowed.but you must use update function to show in the screen.

if there is a '=' you used in Sequence,update function is no need to use.

plot.Sequence.PlotChartPoints[0].Values.Add(1.6f);
plot.Sequence.PlotChartPoints[0].Values.Add(3.4f);
plot.Sequence.PlotChartPoints[0].Values.Add(4.4f);
plot.UpdatePlot();

you will see a photo like this follow:

Mode

here is two modes you can choose,default is REPAINT_PER_DATA

if REPAINT_PER_DATA Mode is selected,update function will redraw whole paint every time you use it.

but in NO_REPAINT Mode,update function will only redraw the new points.

Tips:Before you choose NO_REPAINT Mode,_MinValue and _MaxValue must be set to suitable values.and you'd better set PointNum.

        plot._MinValue = 0;
        plot._MaxValue = 10;
        plot.Sequence = new Sequence(new List<SequenceEntity>() {
        new SequenceEntity(new List<float>() { 1,2,3,4,5,6,7}),
        new SequenceEntity(new List<float>() { 0,5,3,4,5,6,7},Pens.Brown,"example 1"),
        new SequenceEntity(new List<float>() { 0,3,3,4,5,2,1},Pens.Green,"example 2"),
    },PlotLab.PaintMode.NO_REPAINT);

what's more you can clear the paints,when the screen is full of lines.

plot.ClearData();
