| ## 003 - Axis | ||
|
|
||
| This example shows how to handle `Axis` object in order to customise default axes. | ||
|
|
||
| `Axis` is a static attribute initialised after every `Gnuplot.Start()` or `Gnuplot.CleanData()`. The behaviour and methods are the | ||
| same regardless the chosen direction, i.e. X, Y or Z. | ||
| Each `Axis` object has three main component: | ||
| * Range: It defines the axis span (the values to represent between a minimum and a maximum value). | ||
| * Ticks: The marks (values) to represent over the axis. | ||
| * Label: The axis name or meaning. | ||
|
|
||
| Each `Axis` trait can be modified through the set method of the `Axis` class, e.g. `Gnuplot.Axis.SetXRange()` or `Gnuplot.Axis.SetYTicks()`. | ||
|
|
||
| To run the code of axis examples: | ||
|
|
||
| 1. Go to the folder `Examples/003-Axis` | ||
|
|
||
| ```shell | ||
| (SharpPlot)$ cd Examples/003-Axis | ||
| ``` | ||
|
|
||
| 2. The only thing you need to do now is running the project: | ||
|
|
||
| ```shell | ||
| (003-Axis)$ dotnet run | ||
| Press any key + Enter to continue... | ||
| ``` | ||
|
|
||
| And you'll get the following set of figures: | ||
|
|
||
| <img src="Figures/axis-1.png" alt="figure-properties" style="zoom:66%;"/> | ||
|
|
||
| <img src="Figures/axis-2.png" alt="figure-properties" style="zoom:66%;"/> | ||
|
|
||
| <img src="Figures/axis-3.png" alt="figure-properties" style="zoom:66%;"/> | ||
|
|
||
| The code that has produced the figures is the following: | ||
|
|
||
| ```c# | ||
| using System; | ||
| using System.Collections.Generic; | ||
| using System.Linq; | ||
| using SharpPlot; | ||
| using SharpPlot.Canvas.Figure; | ||
| using SharpPlot.Utils; | ||
|
|
||
| namespace Axis | ||
| { | ||
| public static class Program | ||
| { | ||
| static void Main(string[] args) | ||
| { | ||
| Gnuplot.Start(); | ||
|
|
||
| var x = Enumerable.Range(-100, 201).Select(z=>z*0.025*Math.PI).ToArray(); | ||
| var sinX = x.Select(Math.Sin).ToArray(); | ||
| var data = new DataPoints(x, sinX); | ||
|
|
||
| var (id, fig) = Gnuplot.Plot<Line>(data, "sin(x)"); | ||
|
|
||
| Gnuplot.Axis.SetYRange(-2, 2); | ||
| Gnuplot.Axis.SetXTicks(start:-4, step: 0.5, stop:4); | ||
|
|
||
| Gnuplot.Axis.SetXLabel(label: "time [s]"); | ||
| Gnuplot.Axis.SetYLabel(label: "Amplitude [mm]", rotation: 90); | ||
|
|
||
| Gnuplot.Show(); | ||
| Gnuplot.Wait(); | ||
|
|
||
| Gnuplot.CleanData(); | ||
|
|
||
| var (id2, fig2) = Gnuplot.Plot<Line>(data, "sin(x)"); | ||
|
|
||
| var additionalXTicks = new Dictionary<string, double>() { {"pi", Math.PI}, {"e", Math.E} }; | ||
| var additionalYTicks = new Dictionary<string, double>() { {"-pi", (-1)*Math.PI}, {"-e", (-1)*Math.E} }; | ||
|
|
||
| Gnuplot.Axis.SetXRange(0, 8); | ||
| Gnuplot.Axis.AddTicks(labelValues: additionalXTicks, axis: 0); | ||
| Gnuplot.Axis.SetYTicks(ticks: new List<double>(){-4,-2, -1, -0.5, -0.25, 0, 0.25, 0.5, 1, 2, 4}); | ||
| Gnuplot.Axis.AddTicks(labelValues: additionalYTicks, axis: 1); | ||
|
|
||
| Gnuplot.Show(); | ||
| Gnuplot.Wait(); | ||
|
|
||
| Gnuplot.CleanData(); | ||
|
|
||
| var data3D = new DataPoints(x: x, y: sinX, z: sinX); | ||
| Gnuplot.SetPlotType(PlotType.Splot); | ||
| var (id3, fig3) = Gnuplot.Plot<Line>(data3D); | ||
| Gnuplot.Axis.RemoveXTicks(); | ||
| Gnuplot.Axis.SetYTicks(start: -2, stop: 2, num: 11); | ||
| Gnuplot.Axis.SetZRange(-1, 1); | ||
| Gnuplot.Axis.SetZLabel(label: "z", rotation: 45); | ||
| var additionalZTicks = new Dictionary<string, double>() { {"min", -0.75}, {"max", 0.75} }; | ||
| Gnuplot.Axis.AddTicks(additionalZTicks, axis: 2); | ||
|
|
||
| Gnuplot.Show(); | ||
| Gnuplot.Wait(); | ||
| } | ||
| } | ||
| } | ||
| ``` | ||
| There are several things to understand from this example: | ||
| * The axis span can be set with `Gnuplot.Axis.SetXRange()`, `Gnuplot.Axis.SetYRange()` or `Gnuplot.Axis.SetZRange()`, where | ||
| the minimum and maximum values are specified. By default, this method sets 5 ticks between both limits. | ||
| * In order to define axis span and ticks simultaneously, `Gnuplot.Axis.SetXTicks()`, `Gnuplot.Axis.SetYTicks()` or `Gnuplot.Axis.SetZTicks()` provide | ||
| better handling. The ticks can be initialised as a custom-defined `IEnumerable<double>` or a fixed-length sequence (start-step-stop or start-stop-number). | ||
| * Additional ticks can be included using `Gnuplot.Axis.AddTicks()` method, whereas the entire axis ticks can be removed using `Gnuplot.Axis.RemoveXTicks()`, | ||
| `Gnuplot.Axis.RemoveYTicks()` or `Gnuplot.Axis.RemoveZTicks()`. | ||
| * The axis label is added using `Gnuplot.Axis.SetXLabel()`, `Gnuplot.Axis.SetYLabel()` or `Gnuplot.Axis.SetZLabel()`. The rotation parameter configures | ||
| the label orientation. | ||
| * A 3D figure can be plotted setting the plot type to `Splot` in `Gnuplot.SetPlotType()` method. | ||
