我正在使用jpgraph
库绘制条形图,但我正在寻找一种方法来进行一些更改,例如:(a)X轴已经有文本A,B,C,D。如何添加另一组文本,例如,图A有3条,我想将每个条标记为给定的1、2、3。 >
(b)如何在条形图的顶部写入每个条形图的值?
<?php // content="text/plain; charset=utf-8"
require_once ('jpgraph/jpgraph.php');
require_once ('jpgraph/jpgraph_bar.php');
$data1y=array(47,80,40,116);
$data2y=array(61,30,82,105);
$data3y=array(115,50,70,93);
// Create the graph. These two calls are always required
$graph = new Graph(350,200,'auto');
$graph->SetScale("textlin");
$theme_class=new UniversalTheme;
$graph->SetTheme($theme_class);
$graph->yaxis->SetTickPositions(array(0,30,60,90,120,150), array(15,45,75,105,135));
$graph->SetBox(false);
$graph->ygrid->SetFill(false);
$graph->xaxis->SetTickLabels(array('A','B','C','D'));
$graph->yaxis->HideLine(false);
$graph->yaxis->HideTicks(false,false);
// Create the bar plots
$b1plot = new BarPlot($data1y);
$b2plot = new BarPlot($data2y);
$b3plot = new BarPlot($data3y);
// Create the grouped bar plot
$gbplot = new GroupBarPlot(array($b1plot,$b2plot,$b3plot));
// ...and add it to the graPH
$graph->Add($gbplot);
$b1plot->SetColor("white");
$b1plot->SetFillColor("#cc1111");
$b2plot->SetColor("white");
$b2plot->SetFillColor("#11cccc");
$b3plot->SetColor("white");
$b3plot->SetFillColor("#1111cc");
$graph->title->Set("Bar Plots");
// Display the graph
$graph->Stroke();
?>
编辑:我通过在代码末尾添加找到(b)的解决方案:
$b1plot->value->Show(); $b2plot->value->Show(); $b3plot->value->Show();
我仍然没有找到(a)的解决方案。

您可以通过->legend = '1';
在每个bar_plot上设置图例
