问题描述

我正在尝试创建类似

但是我无法获得x和y轴抽动我尝试过类似的操作,以查看x轴运动是否即将到来

But I was not able to get the x and y axis tics coming inI tried something like this to see if the x axis tics are coming

my @data = (
        [0, 0, 10],
        [0, 1, 10],
        [0, 2, 10],
        [],
        [1, 0, 10],
        [1, 1, 5],
        [1, 2, 10],
        [],
        [2, 0, 10],
        [2, 1, 1],
        [2, 2, 10],
        [],
        [3, 0, 10],
        [3, 1, 0],
        [3, 2, 10],
       );

my $chart = Chart::Gnuplot->new(
    output => "test1.png",
    title  => "3D plot from arrays of x, y and z coordinates",
    xlabel => 'x',
    ylabel => 'y',
    xtics  => {
        labels => ['"pi" 3.1416', '"-pi" -3.1416'],
    },

);
$chart->set(pm3d => 'map');
$chart->set(palette => 'defined (0 0 0 1, 1 1 1 0, 2 1 0 0)');
my $dataSet = Chart::Gnuplot::DataSet->new(

    points => \@data,
);

$chart->plot3d($dataSet);

我不确定数据集应该如何以及应该如何添加x和y轴抽动我用从互联网上获得的一些示例测试了上述内容,但看不到结果.任何帮助获得像图像一样的帮助将不胜感激

I am not sure how the dataset should be and how the x and y axis tics should be addedI tested the above with some examples that I got from the internet but was not able to see the result .Any help to get this like the image would be greatly appreciated

还有一个问题,当试图获取X和Y轴上的所有值时,xtics和ytics并未如上图所示充分显示,我得到的似乎是这样的

Got one more issue, when tried to get all the values on X and Y axis, the xtics and ytics are not showing fully as in the above image, the one I got seems like this

数据集是这样的

推荐答案

以下是如何设置轴标签的示例:

Here is an example of how you can set the axis labels:

use strict;
use warnings;
use Chart::Gnuplot;

my @data = (
        [0, 0, 10],
        [0, 1, 10],
        [0, 2, 10],
        [0, 3, 10],
        [],
        [1, 0, 10],
        [1, 1, 5],
        [1, 2, 10],
        [1, 3, 10],
        [],
        [2, 0, 10],
        [2, 1, 1],
        [2, 2, 1],
        [2, 3, 10],
        [],
        [3, 0, 10],
        [3, 1, 0],
        [3, 2, 5],
        [3, 3, 10],
       );

my $chart = Chart::Gnuplot->new(
    bg         => 'white',
    pm3d       => 'map',
    palette    => 'defined (0 0 0 1, 1 1 1 0, 2 1 0 0)',
    output     => "test.png",
    title      => "3D plot from arrays of x, y and z coordinates",
    xlabel     => 'x',
    ylabel     => 'y',
    xtics      => {
        labels   => ['"0030" 0', '"0100" 1', '"0130" 2', '"0200" 3'],
        rotate   => 90,
    },
    ytics      => {
        labels   => ['"04-Oct" 0', '"03-Oct" 1', '"02-Oct" 2', '"01-Oct" 3'],
    },
);
my $dataSet = Chart::Gnuplot::DataSet->new( points => \@data );
$chart->plot3d($dataSet);

更新:

您可以在这样的循环中创建 xtics (给定DataTime $ dt ):

You can create the xtics in a loop like this (given a DataTime $dt):

my @xtics;
for ( my $i=0; $i<($interval_count-1); $i++ ){
    $dt->add(minutes => $interval_period);
    my $xtic = '"' . $dt->hour . ':' . $dt->minute . '"' . ' ' . $i;
    push @xtics, $xtic;
}

然后将 xtics 参数设置为 Chart :: Gnuplot-> new(),如下所示:

Then set the xtics parameter to Chart::Gnuplot->new() like this:

xtics => { labels => \@xtics, rotate => 90, },

这篇关于使用Chart :: Gnuplot Perl的热图的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
